Authentication - Postbase

The Postbase REST API is authenticated with an API key. Generate one under Developers in the app, then send it as a bearer token.

Base URL

https://www.postbase.so/api/v1

Authorization header

curl https://www.postbase.so/api/v1/channels \
  -H "Authorization: Bearer pb_live_…"

Every request must include Authorization: Bearer <your key>. Requests without a valid key return 401 Unauthorized. A key is scoped to the workspace it was created in.

Keys are shown once at creation. Store yours securely; rotate or revoke it from Developers if it leaks.
