Error MessageAuthentication header included, but incorrectly formatted
Error Codeauthentication_malformed

Common causes

  • You included an Authorization header, but the API couldn't understand it. This suggests it's in the wrong format.

  • There may be a proxy between you and Paddle that's changing the Authorization header.
