I was able to get user idp tokens by using “Get a token manually” process here: Management API Access Tokens
However, when I attempt to follow “Automate the Process” via node.js request module from my terminal or app, Management API Access Tokens I get an error message as below: { error: ‘unauthorized_client’, error_description: ‘Grant type 'client_credentials' not allowed for the client.’, error_uri: ‘Application Grant Types’ }
What would be the best way to resolve this error…? Your support would be really appreciated.
