Authentication

Customer should create a username and password in AppNexus.

For an explanation of the errors that you may encounter during and after authentication, see Error Messages.

If your username and password do not grant you access to the API, please refer to the API Onboarding Process or contact your Xandr representative.
If you have forgotten your username or password, you can use the Account Recovery Service to retrieve your username or create a new password.

Next you can add the information in the TPP Tab in the Settings page and check the credentials.
