SendGrid API Key not working in N8N

Questions

Describe the problem/error/question

I have a SendGrid API key that works just fine via a Header when I’m sending email via Postman.

When I put that in the SendGrid API Credentials, N8N shows an error message.

What is the error message (if any)?

" Couldn’t connect with these settings, Forbidden"

Hey @sg_tech,

Does the API key have access to /marketing/contacts? This is the endpoint we use for testing credential but if you are using a restricted access key it may not be allowed to list contacts but the node should still work.

Apologies for delay in reverting back.

Yes, the Credentials show an error but the actual SendGrid Send Email Node works as expected!

Thanks a lot for the guidance!!!
