The wizard for the IA to set up the shopify connection for me was buggy, confusing, and can left me blocked for days, in a loop that goes nowhere. This is the documentation for this step
If you had this problem, this is how i was able to complete this successfully, I don’t have exact steps, because it is confusing, but my tips are below after doing it 3 times and once with the Support team.
The problem is between steps 6 and 7, and there is a step in between where it asks you for a new or existing connection.
Make sure you are logged into the Shopify app and correct store. Whenever you are in a Shopify page or screen, look at the top right and verify that you are still in the correct store.
Create a new OAuth 2.0 connection first. Give it a clear name that you can remember distinguish from other connections like Shopify Staging A, this never works the first time, so continue.
You will be taken back to the same Starting page as if nothing happened. Retry the same process to setup a shopify connection, but this time select Use existing connection, the one you created before Shopify Staging A. This usually does not work either.
Now to try the shopify connection process again from the same integration app start page, but this time select the existing connection that looks bogus, it has a generic name like shopifystore or Shopify Connection or something that does not bear relation to the connections you set up previously. For some reason it then pulled in the credentials from the real Staging A, B, or C connections, and shows a new screen in step 7 of the Celigo document link above. It is asking you for permission to access data from shopify, press agree or continue and it should be done.
The other connections i created are not used by the app after this step, it only uses the shopify connection
