Custom Shopify App Development & API Integrations
About Custom Shopify App Development & API Integrations
Sometimes no app on the market does exactly what your business needs. We build private, custom Shopify apps and integrations that connect your store to your other systems and automate your specific workflow, using Shopify's official APIs and secure authentication.
Who needs this
Merchants with a unique workflow, internal tools or systems that need to talk to Shopify.
What's included
- Discovery session and written requirements
- Technical design with data flow and permissions
- Private app built with the Shopify Admin or Storefront API
- Webhooks for real-time updates where needed
- Secure authentication with minimum permissions
- Error handling, retries and logging
- Testing on a development store before going live
- Source code and documentation delivered to you
- 30 days of bug-fix support after launch
Built the way Shopify intends
We use official APIs and respect rate limits, so your integration stays stable as Shopify updates.
You own it
The code and documentation are yours. We don't lock you into our hosting or tools.
What this doesn't promise
A public App Store listing. Public apps need Shopify review and additional work, which we scope separately. Shopify's platform rules and API limits shape what is possible. We tell you up front what can be built cleanly and what would be fragile, before you pay for it.

A custom front end uses the same API, see headless and Hydrogen storefronts. Integrations with business tools are covered by ERP and 3PL integration, a lighter route is a custom dashboard web app, and the lightest is Google Apps Script automation.
Delivery: 2–8 weeks · Format: Working private app or integration + source code + documentation
