I can’t find the url http://path_to_your_api of my API.
Heya @json ,
The idea here is the API is an endpoint you are running on your own infrastructure.
When you register an API in Auth0 you are just allowing Auth0 to recognise the requested audience by matching it to the API’s configured Identifier, and then Auth0 will generate a token that could be consumed by your API.
So in other words, registering an API in Auth0 is not creating an actual endpoint. You need to provide the API in this scenario 
We have some quickstarts for creating your own backend with API endpoints here: Auth0 Backend/API Quickstarts
Oh, I see. Thank you!
No worries! We’re here for you!
