redirect_uri_mismatch

Seems you didn’t set the callback URL properly on the Salesforce side

Hi there, for your problem, I think it’s coming from your side in salesforce service.
Have you tried to re-check your redirect_url that you fill in Salesforce service?

[Tal_Benhamou]

I did configure it as it’s mentioned on the documentation (screen 1 is my app settings and screen 2 is the n8n doc)

Yes and I did configure it as it’s mentioned on the documentation (screen 1 is my app settings and screen 2 is the n8n doc)

Do you think it can be something else?

You can’t use localhost as a callback address. Moreover, generally, it should be set as https endpoint.

Configure webhook URLs with reverse proxy | n8n Docs

You will need some reverse proxy for that to work. Like nginx, Apache, ngrok, AWS ALB, or any other
