Always get error when trying to connect develop apps api

Retired Boards Appdev Authentication

Topic summary

A developer is encountering an authentication error when attempting to connect to Shopify’s API: “Invalid API key or access token (unrecognized login or wrong password).” Despite creating the app, setting permissions, and installing it on their store, the connection fails.

Current Issue:

  • Error persists even after proper app setup
  • Python code implementation shown in attached screenshot
  • Configuration details provided in images

Suggested Solution:
Another user recommends following Shopify’s best practices for authentication:

  • Add the access token as a header attribute instead of prefixing it in the URL
  • Use the proper URL format: https://[your-shopify-domain]/admin/api/[api-version]/[endpoint]
  • Reference the official Shopify Admin REST API authentication documentation for correct implementation

Status: The discussion remains open with one proposed solution but no confirmation of resolution.

Hi There,

I know that its possible to access the admin api by prefixing the url with the api token and access token but the best practic would be to add the access token as a header attribute and the URL would look like.

[https://your myshopify domain]/admin/api/[api-version]/[endpoint]

Take a look at this example from the docs:
