I'm trying to make an API Call for quickbooks inside a deal based workflow (customized action, not using the current integration), but Quickbooks requires oauth2 in order to get a token from them.
Currently the secrets have limits of characters and my client secret is too big, also what's the callback URL i should use. Has anyone tried this before inside a workflow?, i would really apreciate some guidance.
ps. Our account is professional, so no serverless functions or Github integration...
