Hi everyone, I need help with a problem adding token to the authorization header in an Angular HttpClient call, the token doesn’t work and I get a 401 “unauthorized” error.

I followed this documentation to implement the interceptor:

[Call an API - Angular AuthHttpInterceptor](https://github.com/auth0/auth0-angular/blob/master/EXAMPLES.md#call-an-api)

I have an AWS API Gateway and a JWT authorizer in the routes. When I disable JWT it works fine and i get the data and when i a do postman test it works too, but when I add JWT to routes in API Gateway it doesn’t work and I get this 401 error. I think that the focus is in Auth0 configuration.  
If anyone knows what can i do, I would greatly appreciate it. Thank you.

Hi @antonia7,

Are you seeing the access token in the request? You should be able to look at the _Network_ tab of DevTools and see what is going on.
