Hey anyone there from N8N. The app BREVO is not working. Issue 3 different API keys and all of them fail the connection. I tried the API key in both expression and fixed field. I always get
Couldn’t connect with these settings
Authorization failed - please check your credentials
I may have found the problem.
Apparently in order to use the API in Brevo, the IP address you’re calling from has to be whitelisted, or the “Blocking” feature disabled.
Here is the page where you can set this: Brevo
After I added my IP, it all started working.
