api integration

[iskoc]

I have an external accounting app that I use for my companies account management which provides API integration with shopify stores

The problem is I got an error says I need to check API token if it is correct when I try to connect by API key and API secret (custom app) 

I got in touch with help section, I've been told that I may find solution here with your masters' help

Hi @iskoc!

You may be referring to a legacy authentication workflow regarding API key and secret to connect to the app. Custom apps require access tokens for making authenticated requests.

You can use the steps in the help center docs to get the access token, which can then be included in the request as a header called "X-Shopify-Access-Token".
