RapidAPI allows you to add hidden parameters and headers to your requests. These are added to every request made to your API by the RapidAPI proxy, but are hidden from the API users.
Pro tip: Use your own API key
If you already have API key generation for your API, you can use hidden parameters to authenticate your API requests.
Create a single API key on your system for all requests coming from RapidAPI. You can then set that API key as a hidden header/parameter.
To add a hidden header or parameter, open the 'Settings' tab of your listing and locate the 'Transformations' section.
