# Fetch a development API key

For easy testing of mobile apps and other clients and against Zulip
development servers, we support fetching a Zulip API key for any user
on the development server without authentication (so that they can
implement analogues of the one-click login process available for Zulip
development servers on the web).

**Note:** This endpoint is only available on Zulip development
servers; for obvious security reasons it will always return an error
in a Zulip production server.

`POST {{ api_url }}/v1/dev_fetch_api_key`

## Usage examples
