I'm trying to build custom connector for Business Central. I have all the information for oAuth2, it is working in Postman but in Power Automate I receive the following error:
I tried deleting the custom connector and building it again, tried logging in incognito mode, cleared cache but nothing worked. When I choose authentication: oAuth2.0, I enter client_id, client_secret and all the other required fields but still get the error that I'm missing client_id when try to test the connector. I save and create connector before testing it.
So, in postman it is working fine.
Please help, any suggestion will help me.
