Our API authenticates requests using your  username or API Key. If either one or both are incorrect you will get the error "Supplied authentication is invalid".

Here are a few ways you can ensure you are using the correct credentials : 

  • If you are on sandbox make sure your username is sandbox 
  • If you are on the live environment make sure you are using your application username. Here's how you can view your application username:

  • Make sure the API Key is correct. You can try regenerating a new API Key, just follow the steps in this article
  • Remember that you need to generate a separate API Key for the sandbox environment and a separate API Key for the live environment.
