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 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
a webview, and the credentials are returned to the app (encrypted) via a redirect
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 an API key manually.
In a Zulip development environment,
see also the unauthenticated variant.
