Getting Started with the HydroForecast API

The HydroForecast API enables users to retrieve forecasts and observations and push observations. All versions of the API require authentication and HTTPS for secure communication and primarily use the JSON data format.

Each request must be authenticated by sending your API key as the value of the Authorization header. See HydroForecast API Authentication for more information and a link to your API key.
