I contacted PayPal. My Mass Pay is enabled and I’m still getting an error message.

PayPal rejected your mass payment. Error details:

Code: 10002
Message: Security header is not valid
Severity: Error

I didn’t see that in the documentation so I don’t know how to do that. I tried using the Add Third Party Permissions using “MassPay API” and “MassPay” as the username and it comes back with error of invalid username.

The credentials I used are correct. I copied and pasted them.
