Fetch an API key (production)

This API endpoint is used by clients such as the Zulip mobile and terminal apps to implement password-based authentication. Given the user's Zulip login credentials, it returns a Zulip API key that the client can use to make requests requests as the user.

This endpoint is only useful for Zulip servers/organizations with EmailAuthBackend or LDAPAuthBackend enabled.

The Zulip mobile apps also support SSO/social authentication (GitHub auth, Google auth, SAML, etc.) that does not use this endpoint. Instead, the mobile apps reuse the web login flow passing the mobile_flow_otp in a webview, and the credentials are returned to the app (encrypted) via a redirect to a zulip:// URL.

Note: If you signed up using passwordless authentication and never had a password, you can reset your password.

See the API keys documentation for more details on how to download API key manually.

In a Zulip development environment, see also the unauthenticated variant.
