Authentication

Universal PUSH uses project44's standard OAuth2 authentication. Obtain an access token with your project44 client credentials and pass it as a Bearer token on every request. See the Authentication guide for creating a client application, assigning roles and access groups, generating a token, and rotating credentials.

Authorization: Bearer <your-access-token>

Proxied push

For proxied-push scenarios — where a transportation management system (TMS) or third-party logistics provider (3PL) pushes on behalf of a carrier — include optional carrier-identifier keys (scac, dotNumber, mcNumber) in the identifiers object to disambiguate the actual carrier. The connection owner remains your canonical project44 identity; the carrier identifiers are advisory disambiguators.
