Authentication Token

All TMS REST API authentication is via tokens using an API token passed by the client via the X-AUTH-TOKEN header, and all requests to TMS secured via HTTPS. Each API token is 32 characters long, and TMS supports the ability to have multiple tokens active at the same, allowing for rolling password changes on the client side, or to control access from multiple clients leveraging the same API user. Tokens are generated by TMS and cannot be supplied by the Customer.
