API access is unclear

[Gary_Lynn]

Resolved the problem myself thanks to this post:

API password?

The dedicated password is to hide your real password. So if your key ever became compromised, you could just delete the key and your personal data would remain secure. When you ask for an access token from the API you’ll need to provide the dedicated password instead of your user password for the “password” field.

Once I set the password for the API key and used that instead it worked fine.
