Timeline depends on feature scope, team experience, and testing requirements.<\/span><\/p>\n<h3><strong>What Programming Languages Can I Use to Build a Shopify App?<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">While Node.js is most common, you can <a href=\"https:\/\/ecommerce.folio3.com\/blog\/how-much-does-it-cost-to-build-a-shopify-app\/\">build Shopify apps<\/a> using Ruby, PHP, Python, or any language supporting REST API calls. The Shopify CLI officially supports Node.js and Ruby templates, making these paths most efficient.<\/span><\/p>\n<h3><strong>Do I Need to Know GraphQL to Build a Shopify App?<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Not initially. Start with Shopify&#8217;s REST API for simpler operations. GraphQL becomes valuable as your app scales and you need more efficient data queries. Many successful apps use REST exclusively for their entire functionality.<\/span><\/p>\n<h3><strong>Can I Charge for My Shopify App?<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Yes, but only public apps listed on the Shopify App Store can use the Billing API to charge recurring subscriptions. Custom and private apps typically use direct contracts or separate payment processing.<\/span><\/p>\n<h3><strong>What Happens if My App Breaks After a Shopify API Update?<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Shopify provides advanced notice of API changes and maintains versioned APIs. Subscribe to developer changelogs, test against beta API versions, and plan regular maintenance windows to address deprecations before they impact merchants.<\/span><\/p>\n<h3><strong>How Do I Get My App Featured in the Shopify App Store?<\/strong><\/h3>\n<p><span style=\"font-weight: 400;\">Exceptional apps may receive Shopify&#8217;s &#8220;Built for Shopify&#8221; designation through audit.
