That judgement is based on visual signals \u2014 load speed, image quality, layout clarity, and brand coherence \u2014 not product quality, which they have not yet had time to evaluate. A store that fails the three-second trust test loses the visitor before a single product is seen.<\/p>\n<p>But passing the trust test is only the entry requirement. What separates stores that convert from those that merely look credible is a set of deliberate structural decisions about how buyers move through the experience \u2014 from landing to product discovery to the add-to-cart action to checkout completion. These decisions constitute <strong>UI\/UX design<\/strong> for ecommerce, and they are the subject of this article.<\/p>\n<p>For concrete reference points, our breakdown of <a href=\"https:\/\/cworks.id\/ecommerce-website-examples-indonesia\/\">ecommerce website examples in Indonesia<\/a> covers eight live stores analysed for exactly these qualities. The principles below are abstracted from what those stores \u2014 and the best-performing Shopify stores globally \u2014 consistently get right.<\/p>\n<hr \/>\n<h2><span class=\"ez-toc-section\" id=\"7_Online_Store_Design_Principles_for_Indonesian_Sellers\"><\/span>7 Online Store Design Principles for Indonesian Sellers<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"1_Mobile-First_Design_Design_for_the_Phone_Adapt_for_Desktop\"><\/span>1. Mobile-First Design: Design for the Phone, Adapt for Desktop<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The most important design constraint for any Indonesian online store is that the majority of your buyers will arrive on a smartphone. <strong>Mobile-first design<\/strong> means designing the mobile experience first \u2014 navigation, product images, typography size, button dimensions, checkout flow \u2014 and adapting that experience to desktop, not the reverse.<\/p>\n<p>The practical consequences are concrete. Navigation menus must be thumb-reachable. Product images must load fast and display correctly in portrait orientation. Add-to-cart buttons must be large enough to tap without zooming. Checkout forms must minimise typing through autofill support and pre-selected payment defaults. Every element that requires pinching, horizontal scrolling, or excessive tapping is a conversion leak on mobile that desktop-designed stores consistently miss.<\/p>\n<p><a href=\"https:\/\/developers.google.com\/search\/docs\/crawling-indexing\/mobile\/mobile-first-indexing\" target=\"_blank\" rel=\"noopener nofollow\">Google&#8217;s mobile-first indexing documentation<\/a> confirms that Google predominantly uses the mobile version of a site for indexing and ranking. A store that is not optimised for mobile does not just lose conversion on mobile \u2014 it ranks below mobile-optimised competitors for every relevant search query, regardless of device.<\/p>\n<p>Test your store or any store you are evaluating with <a href=\"https:\/\/pagespeed.web.dev\" target=\"_blank\" rel=\"noopener nofollow\">Google PageSpeed Insights<\/a> on the mobile setting. A score below 70 on mobile represents measurable conversion loss. Stores with scores above 90 load in under two seconds on a mid-range Android device on a standard Indonesian 4G connection \u2014 the most representative test condition for your actual buyer.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Visual_Hierarchy_Guide_the_Eye_Guide_the_Decision\"><\/span>2. Visual Hierarchy: Guide the Eye, Guide the Decision<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Visual hierarchy<\/strong> is the arrangement of design elements so that the most important information is seen first, in the correct sequence. On a product page, the hierarchy should be: product image \u2192 product name \u2192 price \u2192 key benefit \u2192 add-to-cart button \u2192 secondary information (reviews, description, specifications). Every element that appears before the add-to-cart button that does not directly support the purchase decision is adding friction.<\/p>\n<p>According to <a href=\"https:\/\/www.nngroup.com\/articles\/ecommerce-ux\/\" target=\"_blank\" rel=\"noopener nofollow\">Nielsen Norman Group&#8217;s ecommerce UX research<\/a>, the most common visual hierarchy failure on product pages is placing social proof (reviews, endorsements) below the fold \u2014 at a position buyers reach only after they have already decided whether to add to cart. Moving the review summary (star rating and count) to immediately below the product title increases conversion on product pages measurably because it answers the buyer&#8217;s implicit question \u2014 &#8220;is this trustworthy?&#8221; \u2014 at exactly the moment the question forms.<\/p>\n<p>On the homepage, visual hierarchy determines whether a first-time visitor understands within three seconds what the store sells, who it is for, and what the primary action should be. A homepage with five equally sized banners, three promotional carousels, and no clear primary CTA fails this test regardless of how visually polished each individual element is.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone wp-image-25058 size-large\" src=\"https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0041-1024x559.avif\" alt=\"Online Store Web Design \/ desain web toko online\" width=\"800\" height=\"437\" title=\"\" srcset=\"https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0041-1024x559.avif 1024w, https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0041-300x164.avif 300w, https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0041-768x419.avif 768w, https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0041-18x10.avif 18w, https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0041.avif 1408w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Shopify_Theme_Selection_Performance_Over_Aesthetics\"><\/span>3. Shopify Theme Selection: Performance Over Aesthetics<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>For Indonesian brands building on Shopify, <strong>Shopify theme<\/strong> selection is one of the highest-leverage design decisions made before a single pixel of custom work begins. A well-chosen theme provides a performance baseline, a mobile-optimised layout structure, and a flexible section system that allows meaningful customisation without custom code. A poorly chosen theme imposes a performance ceiling that custom development cannot fully overcome.<\/p>\n<p>The <a href=\"https:\/\/themes.shopify.com\" target=\"_blank\" rel=\"noopener nofollow\">Shopify theme store<\/a> offers both free and paid themes across a range of industry verticals. The evaluation criteria that matter for Indonesian stores are mobile PageSpeed score (published for each theme in the store), checkout flexibility, image loading behaviour (lazy loading for product galleries), and language support for Bahasa Indonesia. Themes that score above 80 on mobile PageSpeed before any customisation give you a performance foundation to build on. Themes that score below 60 should be rejected regardless of visual appeal \u2014 custom development will not recover those points.<\/p>\n<p>For brands not yet on Shopify, understanding the platform&#8217;s capabilities is the prerequisite for any theme conversation. Our guide on <a href=\"https:\/\/cworks.id\/what-is-shopify\/\">what is Shopify and how it works<\/a> covers the platform fundamentals before any design discussion begins.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_UIUX_Design_The_Architecture_of_Buyer_Decisions\"><\/span>4. UI\/UX Design: The Architecture of Buyer Decisions<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>UI\/UX design<\/strong> for ecommerce covers two distinct layers. UI (user interface) design concerns the visual presentation \u2014 colour, typography, iconography, spacing, and layout. UX (user experience) design concerns the structure of the buyer&#8217;s journey \u2014 how they navigate, where they land, what actions are available at each step, and how the flow guides them toward purchase. Both matter, but in a clearly defined hierarchy: correct UX structure with adequate visual polish outperforms beautiful UI built on a flawed UX architecture.<\/p>\n<p>The <a href=\"https:\/\/www.interaction-design.org\/literature\/topics\/ux-design\" target=\"_blank\" rel=\"noopener nofollow\">Interaction Design Foundation&#8217;s UX design principles<\/a> establish a framework directly applicable to ecommerce: reduce cognitive load (the number of decisions a buyer must make at any step), provide clear feedback (confirmation that actions have been registered), and maintain consistency (the same element behaves the same way on every page). Stores that violate these principles create confusion \u2014 and confused buyers abandon rather than asking for help.<\/p>\n<p>For Indonesian stores specifically, four UX decisions have outsised impact. First, search functionality \u2014 Indonesian buyers on stores with large catalogues rely heavily on search, and a search bar that returns zero results for common synonyms loses buyers at the highest-intent moment. Second, product filtering \u2014 category pages without functional filters create decision paralysis in large catalogues. Third, cart persistence \u2014 buyers who add items and return to the store the next day expect their cart to be intact. Fourth, guest checkout availability \u2014 forcing account creation before purchase is one of the most documented conversion reducers in ecommerce UX research.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"5_Brand_Identity_Consistency_Builds_Trust_at_Scale\"><\/span>5. Brand Identity: Consistency Builds Trust at Scale<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A first-time buyer arriving at an Indonesian online store has no prior relationship to draw on. Trust is built entirely through signals visible in the first session \u2014 and the most powerful of those signals is visual consistency. A store where the homepage typography matches the product pages, the colour palette is consistent from banner to checkout, and the photography style is unified across the catalogue signals a level of professionalism that inconsistent stores cannot replicate.<\/p>\n<p><strong>Brand identity<\/strong> in ecommerce design is not decoration \u2014 it is trust infrastructure. The specific elements that carry the most trust weight are logo placement and quality (present and correctly proportioned on every page), colour consistency (the same hex values used for CTAs, headers, and accents throughout), photography style (consistent lighting, background, and framing across all product images), and typography hierarchy (the same heading and body font used consistently rather than mixed across pages).<\/p>\n<p>For brands that have not yet formalised their visual identity, investing in brand design before ecommerce build produces a measurably more cohesive store than retrofitting brand consistency onto a live site. Our <a href=\"https:\/\/cworks.id\/services\/branding-design\/\">branding and visual identity services<\/a> cover this foundation work before store design begins.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"6_Conversion_Rate_Optimisation_Design_for_the_Decision_Not_the_Display\"><\/span>6. Conversion Rate Optimisation: Design for the Decision, Not the Display<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Conversion rate optimisation (CRO)<\/strong> in store design means structuring every page element to reduce the distance between arrival and purchase. It is not a separate discipline applied after launch \u2014 it is a design philosophy built into the brief from the first wireframe.<\/p>\n<p>The most impactful CRO decisions in Indonesian store design are predictable across verticals. Social proof placement \u2014 review counts, star ratings, and user-generated content \u2014 must appear above the fold on product pages, not in a reviews tab at the bottom. Urgency mechanics \u2014 low stock indicators, limited-time offer countdowns \u2014 should be used sparingly and only when accurate, because Indonesian buyers are sensitive to perceived manipulation. Cross-sell and upsell placement in the cart \u2014 &#8220;you might also like&#8221; recommendations immediately before checkout \u2014 consistently increases average order value without adding friction to the purchase path.<\/p>\n<p>According to <a href=\"https:\/\/baymard.com\/lists\/cart-abandonment-rate\" target=\"_blank\" rel=\"noopener nofollow\">Baymard Institute&#8217;s checkout research<\/a>, 70% of shopping carts are abandoned globally. The top reasons \u2014 unexpected costs at checkout (shipping, fees), forced account creation, and payment method unavailability \u2014 are all design-solvable problems. A store that shows shipping costs early in the product page, offers guest checkout, and surfaces all Indonesian payment methods prominently at checkout eliminates the three most common abandonment causes in a single design pass.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"7_Checkout_Design_The_Last_Metre_of_the_Conversion_Path\"><\/span>7. Checkout Design: The Last Metre of the Conversion Path<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Checkout design is the highest-leverage single-page optimisation available to any Indonesian online store \u2014 and the most commonly neglected. The checkout is where every trust and friction signal accumulated during the browsing session is either confirmed or undermined. A clean, fast, payment-rich checkout converts the buyer who was persuaded by the product page. A confusing, slow, or payment-limited checkout loses them at the final step.<\/p>\n<p>For Indonesian stores, checkout design has three non-negotiable requirements. First, local payment method coverage: GoPay, OVO, DANA, ShopeePay, virtual bank transfers (BCA, Mandiri, BNI, BRI), and convenience store payments must all be available and surfaced prominently \u2014 not buried in a dropdown below credit card options that most Indonesian buyers do not use. Second, order summary visibility: the product, quantity, price, and shipping cost must be visible throughout the checkout without requiring the buyer to navigate back to confirm what they are paying for. Third, minimal form fields: every additional field in the checkout reduces completion rate. Name, address, and contact detail only \u2014 payment method handles the rest.<\/p>\n<p>Accessibility is an additional consideration that most Indonesian stores have not yet addressed. The <a href=\"https:\/\/www.w3.org\/WAI\/standards-guidelines\/wcag\/\" target=\"_blank\" rel=\"noopener nofollow\">Web Content Accessibility Guidelines (WCAG)<\/a> establish baseline standards for colour contrast, keyboard navigation, and screen reader compatibility. While enforcement is not yet a legal requirement in Indonesia, accessible design improves usability for all buyers \u2014 not just those with accessibility needs \u2014 and is increasingly a criterion in enterprise procurement evaluations.<\/p>\n<hr \/>\n<h2><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"What_is_UIUX_design_and_why_does_it_matter_for_online_stores\"><\/span>What is UI\/UX design and why does it matter for online stores?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>UI (user interface) design covers the visual elements of a store \u2014 colours, typography, layout, and imagery. UX (user experience) design covers the structure of the buyer journey \u2014 navigation, page flow, and the sequence of decisions from landing to checkout. Both matter for ecommerce, but UX structure determines whether buyers reach the checkout at all; UI design determines whether the store feels trustworthy when they get there. A store with strong UX and adequate UI consistently outperforms a visually impressive store built on a flawed user journey.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Which_Shopify_theme_is_best_for_an_Indonesian_online_store\"><\/span>Which Shopify theme is best for an Indonesian online store?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The best Shopify theme for an Indonesian store is one with a mobile PageSpeed score above 80 before customisation, clean product page layouts that support multiple images and variant selection, and checkout flexibility for third-party payment gateway integration. Dawn (free), Impulse, and Prestige are consistently strong performers across these criteria. Theme selection should always start with the published mobile performance score in the Shopify theme store \u2014 visual appeal is secondary to load performance, which directly affects both conversion rate and Google search ranking.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_much_does_online_store_website_design_cost_in_Indonesia\"><\/span>How much does online store website design cost in Indonesia?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Cost varies significantly by scope and provider. A self-built Shopify store using a free theme costs nothing beyond the platform subscription (from USD 29\/month) but requires significant time investment and produces limited customisation. A professionally designed Shopify store from a specialist agency \u2014 covering theme customisation, mobile UX optimisation, brand integration, and checkout configuration \u2014 typically ranges from IDR 15\u201350 million depending on catalogue size and design complexity. Custom-designed stores built from scratch cost substantially more and carry higher ongoing maintenance costs than theme-based Shopify builds.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_long_does_it_take_to_redesign_an_existing_online_store\"><\/span>How long does it take to redesign an existing online store?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A full redesign of an existing Shopify store \u2014 new theme, updated product photography, revised navigation structure, and checkout optimisation \u2014 typically takes 3\u20135 weeks with a specialist agency. This assumes clean product data and a defined brand identity. If the redesign includes a platform migration (moving from a custom-built site to Shopify), add 1\u20132 weeks for data migration and testing. Partial redesigns focused on a single area \u2014 checkout flow optimisation or mobile UX improvement \u2014 can often be completed in 1\u20132 weeks without touching the full store design.<\/p>\n<p><img decoding=\"async\" class=\"alignnone wp-image-25059 size-large\" src=\"https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0042-1024x559.avif\" alt=\"Online Store Web Design \/ desain web toko online\" width=\"800\" height=\"437\" title=\"\" srcset=\"https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0042-1024x559.avif 1024w, https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0042-300x164.avif 300w, https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0042-768x419.avif 768w, https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0042-18x10.avif 18w, https:\/\/cworks.id\/wp-content\/uploads\/2026\/03\/IMG_0042.avif 1408w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/p>\n<hr \/>\n<p>Online store website design in Indonesia is not a one-time decision \u2014 it is an ongoing practice of testing, measuring, and improving. The seven principles above are the foundation: mobile-first structure, deliberate visual hierarchy, performance-oriented theme selection, sound UX architecture, consistent brand identity, CRO built into the design brief, and a checkout configured for Indonesian payment behaviour. Get these right from the start and you build a store that can compound improvement over time.

Aesthetics matter for trust. Structure determines whether that trust converts to revenue. Key Takeaways Over 70% of Indonesian ecommerce sessions happen on mobile \u2014 mobile-first design is not optional, it is the primary design context Visual hierarchy \u2014 the deliberate arrangement of elements by importance \u2014 is more responsible for conversion rate differences between stores than any other single design decision A Shopify theme chosen for mobile performance and checkout flexibility outperforms a visually impressive theme with slow load times and rigid layout UI\/UX design for ecommerce is not decoration \u2014 it is the architecture of how buyers navigate, evaluate, and decide; every element either reduces or adds friction Brand identity consistency across homepage, product pages, checkout, and post-purchase email is what makes a store feel trustworthy to a first-time buyer Conversion rate optimisation (CRO) built into the design brief from day one produces measurably better outcomes than visual redesigns applied to an existing structure Checkout design \u2014 specifically how Indonesian payment methods are presented and in what order \u2014 is the highest-leverage single-page optimisation available to any store What Separates a Good Online Store Design from One That Just Looks Good Indonesian ecommerce buyers make a trust judgement about an online store within the first three seconds of arrival. That judgement is based on visual signals \u2014 load speed, image quality, layout clarity, and brand coherence \u2014 not product quality, which they have not yet had time to evaluate. A store that fails the three-second trust test loses the visitor before a single product is seen. But passing the trust test is only the entry requirement. What separates stores that convert from those that merely look credible is a set of deliberate structural decisions about how buyers move through the experience \u2014 from landing to product discovery to the add-to-cart action to checkout completion. These decisions constitute UI\/UX design for ecommerce, and they are the subject of this article. For concrete reference points, our breakdown of ecommerce website examples in Indonesia covers eight live stores analysed for exactly these qualities. The principles below are abstracted from what those stores \u2014 and the best-performing Shopify stores globally \u2014 consistently get right. 7 Online Store Design Principles for Indonesian Sellers 1. Mobile-First Design: Design for the Phone, Adapt for Desktop The most important design constraint for any Indonesian online store is that the majority of your buyers will arrive on a smartphone. Mobile-first design means designing the mobile experience first \u2014 navigation, product images, typography size, button dimensions, checkout flow \u2014 and adapting that experience to desktop, not the reverse. The practical consequences are concrete. Navigation menus must be thumb-reachable. Product images must load fast and display correctly in portrait orientation. Add-to-cart buttons must be large enough to tap without zooming. Checkout forms must minimise typing through autofill support and pre-selected payment defaults. Every element that requires pinching, horizontal scrolling, or excessive tapping is a conversion leak on mobile that desktop-designed stores consistently miss. Google&#8217;s mobile-first indexing documentation confirms that Google predominantly uses the mobile version of a site for indexing and ranking. A store that is not optimised for mobile does not just lose conversion on mobile \u2014 it ranks below mobile-optimised competitors for every relevant search query, regardless of device. Test your store or any store you are evaluating with Google PageSpeed Insights on the mobile setting. A score below 70 on mobile represents measurable conversion loss. Stores with scores above 90 load in under two seconds on a mid-range Android device on a standard Indonesian 4G connection \u2014 the most representative test condition for your actual buyer. 2. Visual Hierarchy: Guide the Eye, Guide the Decision Visual hierarchy is the arrangement of design elements so that the most important information is seen first, in the correct sequence. On a product page, the hierarchy should be: product image \u2192 product name \u2192 price \u2192 key benefit \u2192 add-to-cart button \u2192 secondary information (reviews, description, specifications). Every element that appears before the add-to-cart button that does not directly support the purchase decision is adding friction. According to Nielsen Norman Group&#8217;s ecommerce UX research, the most common visual hierarchy failure on product pages is placing social proof (reviews, endorsements) below the fold \u2014 at a position buyers reach only after they have already decided whether to add to cart. Moving the review summary (star rating and count) to immediately below the product title increases conversion on product pages measurably because it answers the buyer&#8217;s implicit question \u2014 &#8220;is this trustworthy?&#8221; \u2014 at exactly the moment the question forms. On the homepage, visual hierarchy determines whether a first-time visitor understands within three seconds what the store sells, who it is for, and what the primary action should be. A homepage with five equally sized banners, three promotional carousels, and no clear primary CTA fails this test regardless of how visually polished each individual element is. 3. Shopify Theme Selection: Performance Over Aesthetics For Indonesian brands building on Shopify, Shopify theme selection is one of the highest-leverage design decisions made before a single pixel of custom work begins. A well-chosen theme provides a performance baseline, a mobile-optimised layout structure, and a flexible section system that allows meaningful customisation without custom code. A poorly chosen theme imposes a performance ceiling that custom development cannot fully overcome. The Shopify theme store offers both free and paid themes across a range of industry verticals. The evaluation criteria that matter for Indonesian stores are mobile PageSpeed score (published for each theme in the store), checkout flexibility, image loading behaviour (lazy loading for product galleries), and language support for Bahasa Indonesia. Themes that score above 80 on mobile PageSpeed before any customisation give you a<\/p>","protected":false},"author":4,"featured_media":25057,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[49,547,159,220],"tags":[544,57,164,553],"class_list":["post-25055","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-shopify","category-online-store","category-ui-ux","category-web-design","tag-indonesia","tag-shopify","tag-ui-ux","tag-web-design"],"acf":[],"_links":{"self":[{"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/posts\/25055","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/comments?post=25055"}],"version-history":[{"count":3,"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/posts\/25055\/revisions"}],"predecessor-version":[{"id":25090,"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/posts\/25055\/revisions\/25090"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/media\/25057"}],"wp:attachment":[{"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/media?parent=25055"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/categories?post=25055"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cworks.id\/id\/wp-json\/wp\/v2\/tags?post=25055"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
