SendGrid Extension Block Integration

[NeptuneDev]

We are trying to integrate SendGrid in the Airtable Extensions. I created a new API key in SendGrid and verified my email, however, upon trying to finish the integration, I get the following error: Invalid SendGrid API key or sender email address. 

Any suggestions? I have already tried creating a new API and re-verifying the email.

In SendGrid, you manage your senders in the left margin underneath Marketing > Senders.

Your API key can only be used with those email addresses.

If you’re already using those senders, I would try with Make’s SendGrid automations & integrations to see if you get the same error there.

Thanks for your response! Airtable has let me know that there was an issue in the backend but that the fix should be implemented by Monday morning.

is it possible to inspect the HTTP Header and see what is being sent, if possible try it on Postman first to isolate which environment might be causing the issue.
