Brevo API key won’t be accepted (API key not valid)

Follow this guide if you’re trying to add an API key from Brevo and it keeps getting rejected.

Written by David Terrey

Every now and then this error message shows up when you paste in your Brevo API key:

If you get that error, work through these steps:

  1. Click "Unauthorised IP addresses":

  2. Allow the address whose provider is "AMAZON-AES":

If that doesn’t do it, get in touch with support and we’ll work out a fix for your specific setup.
