# Platforms

Platform API keys allow you to create new gyms and execute requests on behalf of connected gyms.

To act as a connected gym, clients can issue requests using the `wodup-gym` special header. Make sure that this header contains a WodUp gym ID, which starts with the `gym_` prefix.

<RequestExample>
  ```bash Request theme={null}
  curl https://api.wodup.dev/api/public/athletes \
    -u sk_test_abc123: \
    -H "wodup-gym: gym_123abc"
  ```
</RequestExample>

<Tip>
  Do not include a `wodup-gym` header if creating a new gym (`POST
      /api/public/gyms`)
