I will build a custom shopify private app for API integration and automation


About this gig
Are you tired of fighting with "off the shelf" apps that don't quite do what you need? Is your team wasting hours every day on manual data entry between Shopify and your external software?
The truth is: Generic apps lead to generic results. If your business has a unique workflow, trying to force it into a standard app is costing you time, increasing errors, and leaking profit. You don't need another subscription; you need a custom solution that fits your business like a glove.
I build high performance Shopify Private Apps that bridge the gap between your store and the tools you love. Whether its a custom ERP sync, a complex inventory automation, or a unique customer portal, I deliver secure, scalable, and seamless integrations using the latest Shopify GraphQL Admin API.
WHAT YOU WILL GET?
Custom Private App: Hosted securely and tailored to your exact business logic.
Seamless API Integration: Connect Shopify with CRM, ERP, 3PL, or any external API.
Workflow Automation: Eliminate manual tasks (Order sync, custom pricing, bulk updates).
Clean & Scalable Code: Built with Node.js/React or PHP, optimized for the 2026 Shopify infrastructure.

FAQ
Why do I need a Custom Private App instead of a public app from the Store?
Public apps are built for the masses. They often come with monthly subscriptions, bloated code that slows down your site, and features you don’t need. A Private App is built exclusively for your store. It does exactly what you need, owns your data, and has zero recurring monthly app fees.
Do you provide hosting for the Custom App?
No. To ensure you have 100% ownership and security of your data, the app should be hosted on your own server (AWS, Heroku, or DigitalOcean). Don't worry—as part of the service, I will handle the deployment and walk you through the simple setup process so you own the keys to your kingdom.
Will this app break when Shopify updates their API?
I build using the latest Shopify GraphQL Admin API standards. Shopify typically provides a stable version for 12 months. I write "future-proof" code, and I offer maintenance packages to ensure your app stays compatible with every version update Shopify releases.
. Can you integrate Shopify with YOUR SOFTWARE
If the software has an open API (REST or GraphQL), I can connect it. Before ordering, please send me the API documentation of the software you want to integrate. If they don't have an API, I’ll tell you upfront so we don’t waste each other’s time.
What do you need from me to get started?
I need a clear "User Story." Tell me: "When [X] happens in Shopify, I want [Y] to happen in [Software Z]." Once I have the logic and the API credentials, I can begin. If you aren't sure about the logic, we can start with a Consultation Phase to map it out.
