Howdy, I’m trying to build a private Trustpilot integration to make use of the Generate service review invitation link API call, which the currently isn’t an available action for the Trustpilot Zap. I had tried using the Custom Action to build that call but ran into some issues there as well - here’s the community post I spun up about that 

My current issue has been with successfully adding authentication to this private integration. It looks like the authentication steps expect an Authorization Code Grant Type from the Oauth2 authentication, however, I have been failing to successfully completely the login. I’ve entered what I believe is the correct endpoints and credentials. When I attempt to connect, it opens the sign in page for Trustpilot, I enter my email, which then sends a login link to my email. However, the link opens to a Trustpilot login page that never logs me in and there are console errors in the developer view of my browser. 

When I reached out to our Trustpilot contact, they mentioned that they prefer using the Client Credentials grant type, however, I don’t believe that’s an option here for Zapier integrations. I was just curious if anyone had any advice on successfully using the Trustpilot Authorization code grant type or if we can use the client credentials when building a private integration.
