Headers Sent by API Proxy

Headers sent to the request

If you are an API provider, you will receive some additional headers appended in the request to your servers:

This is a secret unique key for every API that is appended by the proxy on every request. For high security, you can validate this secret server-side and check if it equals the key shown in the API Admin (under the ‘Settings’ tab at provider.rapidapi.comm).

The username of the user that’s making the request.

The name of the subscription (if any). The values can be:

  • FREE
  • CUSTOM (if the user is subscribed to a custom plan.)

The version of the proxy

The IP address of the client making the request. It could be shown in a comma separated format like “,” where the first IP address belongs to the client and any subsequent IP represents a proxy.

Headers sent as response

When consuming an API on Rakuten RapidAPI, you will always receive the following headers appended to the response:

The current version of the API proxy used by Rakuten RapidAPI.

The number of requests the plan you are currently subscribed to allows you to make, before incurring overages.

The number of requests remaining before you reach the limit of requests your application is allowed to make, before experiencing overage charges.

This header is set to true when the RapidAPI proxy generates the response, (i.e. the response is not generated from the provider)
