I've taken the HERE Reverse geocoding API endpoint from the docs and I can successfully make a GET request in Postman with some random lat/long coords. This is the endpoint:
However, this does not work in the client. From my Angular app, I get a 401 http status error. I've seen answers questions regarding app_id and app_code, but according to HERE's Developer Support's comment here, api_key has replaced those other parameters at an endpoint that does not work for me neither in my client or Postman. I do not see anywhere in the HERE project that whitelists domains. I am passing a valid api_key (obvious).
