API Reference

API baseURL

For all API calls to the Growth Charts API, you should use the baseURL 

https://api.rcpch.ac.uk/growth/v1

  • path: Our API path naming policy (growth) is designed to allow the same baseUrl to be used for other APIs in the future.

  • versioning: We have versioned the API v1 to allow for future versions to be developed without interfering with existing integrations.

  • relative: All API requests should be made to this URL, and the endpoints described in the API definition are relative to this base URL.

  • authentication: The API will return Unauthorized or Not Found (4xx) responses if the request does not include a valid API key.
