Authorization

Authorize your MASV API requests using API keys.

API keys are the only supported authorization method for MASV API integrations. They simplify your application, are easy to rotate, and do not require storing user credentials.

The MASV API also uses scoped JSON Web Tokens internally for package and transfer operations. These tokens are returned automatically by the API when you interact with packages and cloud connections — you do not need to generate them yourself.

All MASV API connections require Transport Layer Security (TLS) 1.2 or 1.3.
