Is there anyone who can help creating Custom App for Shopify partners?

I need to build a centralized, scalable program that automatically retrieves Admin API tokens for all stores connected under a single Shopify Partners account — both existing stores and any new stores added in the future.

Key points:

  1. The program should handle OAuth authorization for each store and securely store the tokens in a central database or Google Sheets.

  2. Tokens will be used to analyze previous day revenue and for further automations in Make (Integromat).

  3. From the Make side, the only task is to request each store’s token via a JQL query — the program should make all tokens accessible for this.

  4. The solution must be scalable, so that whenever a new store is connected to the Shopify Partners account, its token is automatically retrieved without manual intervention.

In short, the goal is a single “token hub” app for all connected stores, enabling downstream revenue analysis and automation workflows in Make.p me to create custom shopify

Build a public Shopify app that asks for offline Admin scopes through OAuth and stores the encrypted tokens for the store in a centralized db or Google Sheets. Register new shops with an app installed webhook and remove tokens with the app uninstalled webhook. Offer a secure api for Make to get the tokens.
