Global Parameters
Endpoint parameters vary by API, but RapidAPI authentication and safe request conventions are consistent across Happy Endpoint APIs.
Required headers
X-RapidAPI-Key
Your RapidAPI application key. Keep it secret and send requests from a backend, worker, or secure server environment.
X-RapidAPI-Host
The API-specific host value shown on the RapidAPI listing. Copy it from the exact API you are integrating.
Query conventions
URL-encode values
Encode search terms, product URLs, locations, and category names so spaces and symbols do not break requests.
Keep secrets out of URLs
Send credentials through headers rather than query strings because URLs often end up in logs and browser history.
