Hi, Did anyone encountered an error
Failure passed to redirect url. error=invalid_request error_description=missing required code challenge when trying to connect the Marketo sandbox to the dev environment of Salesforce? Any idea how to fix it? Marketo's support did not really help
Hi @tamirbe,
The issue is with the Salesforce connected app configuration. Salesforce has started enforcing PKCE (Proof Key for Code Exchange) on some OAuth flows, and Marketo’s sandbox environment doesn’t currently support sending a code_challenge as part of the auth
request.
To fix it, went into Salesforce:
After this, retry the connection from the Marketo sandbox. Hope this will resolve the problem.
