Salutations!
I have just completed my first REST API, deployed on heroku, and I decided it would be cool to make $0 a month through rapidAPI.
The rapidAPI testing dashboard passes the tests successfully - with one of their keys being a requirement for an API call.
However when I access the site on a browser or on Postman, there is no need for an API key and therefore no restrictions in get requests.
I have noticed that the test code makes a fetch request to the rapidAPI url for the project but how can I make the heroku url accessible only from rapidAPI?
I know it's extremely unlikely someone will find my heroku app url but it is technically possible.
I appreciate your time and insights.
