Custom APP Integration

Retired Boards Appdev Authentication

Topic summary

Main issue: A custom Shopify app connecting a store to an ERP returns HTTP 401 (Unauthorized) when the ERP uses the Admin API access token plus API key and secret. The goal is to sync products, descriptions, prices, availability, and quantities. The store is not yet online; it’s unclear if this impacts access.

Latest update: A reply asks how the app was created (via Shopify Admin vs CLI) and links to official guides for generating Admin API access tokens and making authenticated requests. It notes CLI-created apps should already be authenticated during setup.

Context: 401 indicates authentication failed (invalid or missing credentials).

Open questions:

  • Whether the store being offline affects Admin API access.
  • Which app creation method was used, to follow the correct auth flow.

Status: Unresolved/ongoing.

Suggested next steps:

  • Confirm how the app was created (Admin or CLI).
  • Recheck token generation and the documented authentication method from the linked guides.
  • Retest authentication after aligning with the correct flow.

Hello,

I have created my shopify store and I need to connect it to my physical shop ERP System. I have followed all the instructions and I created a custom APP but when I send the Admin API Access token and the API Key and secret key the ERP developers gets 401 ERROR! I want to receive the products, descrptions, prices, availability, quantinty and other information from the ERP.

Note: My Shopify Store is not online yet (Can this make any problems)

Hi Svetoslav1234,

How did you create the custom app (eg: in the Shopify Admin, or via the CLI tool?) For custom apps created in the Shopify admin, you can follow this guide for generating access tokens and making authenticated requests and for apps created with the CLI, these should already be authenticated during the app creation process.
