Auth

Golang library for exchanging IAM principal for a Twisp OIDC token.

Usage

Twisp provides an http.RoundTripper implementation that handles:

• Exchanging IAM principal for a Twisp OIDC token
• Auto-refreshing those tokens on expiration
• Automatically setting the Authorization and X-Twisp-Account-Id headers on HTTP requests
