Grant Warehouse Shipment Page API Access when OAuth Grant Type=Client Credentials

Hi fellow developers,

I am setting up a Service-to-Service authentication in AAD to expose APIs to external warehouse integration partners.

At this stage, I am able to setup the authentication with Grant Type: Client Credentials and it works with regular API Page access, but when I tried to call the warehouse shipment API, I am getting 400 Bad Request:

You must first set up user INTEGRATION PARTNER as a warehouse employee.

I know how to setup warehouse employee if I am accessing via user-impersonation but with Client Credential access, I am not accessing the page as a signed-in user so I cannot setup warehouse employee for the account.

Is there a way to get through the Warehouse Employee setup validation for Service-to-Service authentication? Or the only way I have is to create custom API instead of using the Warehouse Shipment API page.

Thank you,

Ginger

Hi, When you add Azure Active Directory Application in BC, a user will be automatically created, and you can just add this user to Warehouse Employee. This should solve the problem.

Hope this helps.

Thanks.

Thanks a lot ZHU.

I couldn't find the corresponding Username in the Warehouse Employee dropdown list, so I assumed that's not possible. But it looks like I can just type the Username in the Warehouse Employee column and it worked!

Thank you,

Ginger
