Worked “Basic Auth” Example
If the client_id is “my-app” and the client_secret is “my-app-secret-123”,
then the header uses the value B64Encode(“my-app:my-app-secret-123”), which
converts to bXktYXBwOm15LWFwcC1zZWNyZXQtMTIz. This gives you the Authorization
token for “Basic Auth”.
GET header:
Authorization: Basic bXktYXBwOm15LWFwcC1zZWNyZXQtMTIz
