If they aren&#8217;t, customers will come across products that are no longer available, they will be redirected to dead pages, or they will be given prices that are no longer valid. This situation is often where the need for a good API integration arises.<\/p>\n\n\n\n<p>In fact, most retailers don&#8217;t realize how quickly manual syncing is going to become a nightmare. Manually updating a catalog is doable when you only have thirty products. The moment you start managing three hundred products across different collections and seasonal campaigns, the differences between your storefront and your catalog start to cost you sales without you even knowing it.<\/p>\n\n\n\n<p>An API integration addresses this problem by turning your e-commerce platform into the one and only source of truth and allowing your catalog to fetch data from it automatically. If done right, this is completely hidden from both you and the customers. If done wrong, it&#8217;s a very frustrating maintenance chore. The deciding factor is how the integration is created, not merely its existence.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_47_1 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"ez-toc-toggle-icon-1\"><label for=\"item-69f349c919d27\" aria-label=\"Table of Content\"><span style=\"display: flex;align-items: center;width: 35px;height: 30px;justify-content: center;direction:ltr;\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/label><input  type=\"checkbox\" id=\"item-69f349c919d27\"><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/extendsclass.com\/blog\/building-api-integrations-between-digital-catalogs-and-e-commerce-platforms\/#Why_manual_syncing_breaks_down_fast\" title=\"Why manual syncing breaks down fast\">Why manual syncing breaks down fast<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/extendsclass.com\/blog\/building-api-integrations-between-digital-catalogs-and-e-commerce-platforms\/#What_a_good_API_integration_actually_handles\" title=\"What a good API integration actually handles\">What a good API integration actually handles<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/extendsclass.com\/blog\/building-api-integrations-between-digital-catalogs-and-e-commerce-platforms\/#The_platforms_worth_designing_the_integration_around\" title=\"The platforms worth designing the integration around\">The platforms worth designing the integration around<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/extendsclass.com\/blog\/building-api-integrations-between-digital-catalogs-and-e-commerce-platforms\/#Where_integrations_break_and_how_to_prevent_it\" title=\"Where integrations break and how to prevent it\">Where integrations break and how to prevent it<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/extendsclass.com\/blog\/building-api-integrations-between-digital-catalogs-and-e-commerce-platforms\/#Native_middleware_or_custom_Which_route_makes_sense\" title=\"Native, middleware, or custom: Which route makes sense\">Native, middleware, or custom: Which route makes sense<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/extendsclass.com\/blog\/building-api-integrations-between-digital-catalogs-and-e-commerce-platforms\/#When_the_integration_works_nobody_talks_about_it\" title=\"When the integration works, nobody talks about it\">When the integration works, nobody talks about it<\/a><\/li><\/ul><\/nav><\/div>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_manual_syncing_breaks_down_fast\"><\/span><strong>Why manual syncing breaks down fast<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The minute you work with two product data sets simultaneously, they start to diverge. A price update on Shopify that is not communicated to your catalog will lead to customers seeing one price in the catalog and another price at the checkout. This is a trust issue right away, and those customers will hardly ever return.<\/p>\n\n\n\n<p>Price synchronization is a bit simpler than maintaining inventory accuracy. Imagine the scenario of having a catalog listing ten products in stock while the actual inventory level is zero, this would result in order cancellations which are costlier than just losing the sale. Furthermore, you&#8217;ve allocated resources for shipping and fulfillment, customer service, and probable refund, all because the systems weren&#8217;t communicating.<\/p>\n\n\n\n<p>Besides, manual workflows lead to bottlenecks. Your team member has to keep in mind re-exporting product data weekly, cleaning it, and loading it into the catalog platform. This employee becomes a potential failure point. During their vacation, your catalog will be outdated. And when they quit, the process often ends with them.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_a_good_API_integration_actually_handles\"><\/span><strong>What a good API integration actually handles<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>At the very least, the integration should be able to automatically retrieve product data from your e-commerce platform. In other words titles descriptions variants pricing, stock levels, and image URLs should all be transmitted without any person having to copy or paste.<\/p>\n\n\n\n<p>People usually underestimate the value of first hand updates. A price modification, a sold-out status, or a new product variant, each one of these changes should reflect on the catalog within minutes, not days. Batch syncs that run overnight are an improvement over manual updates, but they still create periods during which the catalog displays wrong information.<\/p>\n\n\n\n<p>Besides, the integration should even be able to handle the opposite direction &#8211; at least with regards to sending traffic. So, when a user clicks on a catalog product, the integration has to take them to the correct product page with the right variant being pre-selected and all tracking parameters properly passed through. Otherwise, you will be missing out on attribution and will not be able to tell which campaigns are truly yielding results.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_platforms_worth_designing_the_integration_around\"><\/span><strong>The platforms worth designing the integration around<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Most catalog integrations begin with Shopify, mainly because its API is not only well-documented but also its data model is quite simple. Additionally, many catalog platforms come with built-in Shopify connectors, thereby offering the smoothest solution for retailers who are already using that stack.<\/p>\n\n\n\n<p>WooCommerce is another popular platform though it is more diverse. Given that WooCommerce operates within WordPress, how good the integration is will largely depend on the way the site is set up, which plugins are being used, and if the REST API is accessible. Hence, those on WooCommerce will generally require some additional work for catalog sync to run without any issues.<\/p>\n\n\n\n<p>Magento, BigCommerce, and Salesforce Commerce Cloud are more associated with mid-market and enterprise catalogs. These platforms have more feature-rich APIs but also increased complexity. In fact, the integrations here usually require IT or development teams, and the duration ranges from a few days to a couple of weeks.<\/p>\n\n\n\n<p>A good <a href=\"https:\/\/www.publitas.com\/digital-catalog\/\">digital catalog tool<\/a> with existing connectors to the major platforms removes most of the friction. Instead of commissioning a custom integration for each campaign, retailers can connect their store once and have catalogs pull product data automatically going forward. That&#8217;s the difference between a one-time setup and a recurring technical project.<\/p>\n\n\n\n<p>Custom backends and headless commerce stacks are their own category. If you&#8217;re running a bespoke Node backend or a headless setup with Contentful or Sanity managing product data, expect to build a custom connector. The logic is the same, but the heavy lifting is yours.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Where_integrations_break_and_how_to_prevent_it\"><\/span><strong>Where integrations break and how to prevent it<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>A major source of failure is image handling. Usually product images in your e-commerce store are resized and compressed for website display only, not for catalog purposes. If those pictures end up in a high-resolution catalog setting they are certain to look blurry or pixelated. The integration must be able to deliver images resourcefully, either retrieving higher quality versions or cooperating with a CDN which handles transformations on demand.<\/p>\n\n\n\n<p>Variant handling is also a big hidden issue. If a product consists of twenty color and size variations, it is necessary to represent it in the catalog in a shopper-friendly way without messing up the layout. If the integration treats each variant as a separate product, soon your catalog will be full of almost identical products. On the other hand, if variants are incorrectly merged, the clients will be unable to choose the exact version they want.<\/p>\n\n\n\n<p>Currency and language issues arise as soon as you start selling internationally. The integration has to be informed about which store context it should pull from, and what price, description, and availability is relevant to each audience. A catalog designed for European shoppers but displaying USD prices from a US Shopify store is a small mistake that can be avoided but it happens all the time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Native_middleware_or_custom_Which_route_makes_sense\"><\/span><strong>Native, middleware, or custom: Which route makes sense<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Retailers using standard e-commerce stacks should consider native integrations built directly into the catalog platform as they offer the fastest solution. They do not have any extra infrastructure requirements, the only credential management that is needed, apart from the initial connection, and the updates to the integration are done by the vendor.<\/p>\n\n\n\n<p>Custom sync logic is required in the case of middleware platforms such as Zapier, Make or even dedicated integration tools which can also be used to change data between systems. The downside is that you pay a monthly fee and have an additional service in your stack that can break. If retailers have uncommon workflows, middleware typically will be worth the investment, but in the case of product sync, it is simple and so middleware it is unnecessary.<\/p>\n\n\n\n<p>Real scale and an in-house development team are operating conditions that justify custom integrations, or if you have highly complex requirements that no off-the-shelf solution can handle. The upside of building your own solution is that you have total control but you are also fully accountable. Besides that, plan on an ongoing maintenance budget because APIs on the e-commerce side change more frequently than people think.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"When_the_integration_works_nobody_talks_about_it\"><\/span><strong>When the integration works, nobody talks about it<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>If the catalog-to-commerce integration is working well, you shouldn&#8217;t even notice it. Catalogs reflect products accurately; when shoppers click, they get the correct webpage; inventory levels stay synced; and marketing team doesn&#8217;t spend their Fridays at all. reconciling spreadsheets. In fact it becomes part of the plumbing &#8211; which is precisely the role of infrastructure.<\/p>\n\n\n\n<p>To reach stage requires deciding on the right set of tools, being aware of the data scheme of both sides, and implementing sufficient observability to detect issues before the customers do. It is less thrilling to put a new catalog up, but it is the base that enables every catalog besides the initial one to be more easily shipped.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Selling directly from a digital catalog when your inventory, prices, and product information are actually managed through an e-commerce platform means you have two separate systems that must be in sync with each other.
