I’m trying to use Mailgun to send emails through Postman but keep running into authentication problems. No matter how I format my API key in the authorization header, I always get a 401 unauthorized response.
I’ve attempted different ways of setting up the auth in Postman but nothing works. Even when I try using curl like the docs show, I get a forbidden error:
curl -s --user 'api:xyz123...' \
https://api.mailgun.net/v3/sandbox123.mailgun.org/messages \
-F from='[email protected]' \
-F to='[email protected]' \
-F subject='Test Message' \
-F text='This is a test email message'
Forbidden
What’s the correct way to authenticate with Mailgun API? Am I missing something in the authorization setup?
