If you are thinking about “Why the subscribe endpoint is not working on RapidAPI’s URL?”. Then this tutorial will explain why I have chosen to opt-out of the RapidAPI URL of subscribe endpoint.

Reason 1

When you are using any RapidAPI endpoints in your apps (specifically applications running on the browser) you will expose your X-RapidAPI-Key when sending any request to the RapidAPI endpoint.

Check the below image when I send any request from my web app X-RapidAPI-Key is revealed out & anyone can use it & all of my paid RapidAPIs will be compromised related to that RapidAPI App.

Reason 2

When a request is sent from a browser using RapidAPI endpoint it first reaches RapidAPI’s gateway/proxy & then gateway/proxy forwards this request to my API server. But the problem is RapidAPI gateway/proxy removes some header values which are added by the browser when a request is sent. And these request headers values are essential for the subscribe endpoint to validate the requests.

Hence I have opted out of RapidAPI specifically for the subscribe endpoint.
