This macro can be used to get the authorisation token required for use in Spotify API using the Client Credentials method.
The macro has an interface to allow you to put in the Client ID and Client Secret.
To obtain your Client ID and Client Secret:
1. Go to https://developer.spotify.com/dashboard/login
2. Login with your account or Create a new account
3. Create an app and fill in the form
4. Open the app to find the Client ID and Client Secret
This macro only gives you the authorisation token and nothing else. You will most likely need to concatenate it with string 'Bearer ' in a column and configure the Download tool Header tab.
