I am trying to build a custom integration with trustpilot oauth2 for service reviews and stuck with oauth2 test authentication step.
When I try to do the similar setup in postman I get prompted for a login from Trustpilot and get the authorization code back. But I am stuck with being able to implement the same in Zapier.
The default trustpilot existing app works fine but trying to build integration to send a custom API call.
Any help is highly appreciated.
