Basically the OAuth flow works if the user initiates the request from our webapp but fails if the request is initiated from Pipedrive’s marketplace currently. I believe this is due to some setup that is required prior to activating the integration and the setup doesn’t happen if the flow is initiated from Pipedrive currently.
Welcome to the community and thanks for being patient can you share further details regarding the error? Also how is the current flow setup? feel free to share the technical details.
