Great — here’s your final n8n community post with all details filled in:
Describe the problem/error/question
I’m trying to connect to Salesforce (OAuth2) from n8n (latest version, running on AKS). I have a Connected App in Salesforce with only client_id and client_secret, and we use a custom domain:
https://xyz.my.salesforce.com.
n8n generates a redirect URI, which I copied exactly into the Salesforce Connected App’s OAuth callback URL field.
However, when attempting to authorize, I get a redirect URI mismatch error.
What is the error message (if any)?
error=redirect_uri_mismatch
error_description=redirect_uri must match configuration
Please share your workflow
(Not applicable – issue occurs during credential setup.)
Share the output returned by the last node
N/A – OAuth flow fails before any node is executed.
