summary: >-
  Pabbly uses per-product credentials generated from the account dashboard. Three
  of the five documented REST APIs use HTTP Basic auth with an API Key as the
  username and a Secret Key as the password; two use a Bearer token. The sixth
  API — Connect Platform — uses a Bearer tenant key prefixed pk_live_ plus a
  required x-user-email header naming the end customer the call acts on. No
  OAuth 2.0, no OpenID Connect and no mTLS are published anywhere on the surface;
  every /.well-known/oauth-authorization-server and /.well-known/openid-configuration
  probe returned 404.

        description: >-
          Email of the end customer the call acts on. Required on every
          connection method; the SDK throws before sending if it is missing.
    posture: >-
      Backend-to-backend only. The SDK states the tenant key and vended tokens
      must never reach a browser, a mobile app or an LLM context.

observations:
  - >-
    Credentials are account-wide and unscoped — there is no permissions or scope
    surface published for any Pabbly API, so a key grants whatever the account
    can do. Pabbly's own docs say so: "Your credentials grant full access to your
    account."
  - >-
    Basic-auth products send the secret on every request rather than exchanging
    it for a short-lived token; there is no documented expiry or refresh.
  - >-
    Auth differs per product (Basic vs Bearer) with no shared identity layer,
    so a multi-product integration carries several unrelated credentials.
