Get Google Sheets Authentication ID via Postman

[themacmarketer]

Would someone please be able to advise how I can retrieve a authId via Postman for the Google Sheets API ?

I'm able to get these calls working.

https://.herokuapp.com/api/google-sheets
https://.herokuapp.com/api/google-sheets/authentications/

But when I try to retrieve a token through a put I run into trouble:
e.g. https://.herokuapp.com/api/google-sheets/authentications/60ef157e-ee0a-4aef-bec9-52e4c8a12345

I'm supplying these values via json:

redirect_uri: https://.herokuapp.com/auth/callback
scope: https://www.googleapis.com/auth/spreadsheets
client_id: 12345.apps.googleusercontent.com
client_secret: 123456
setup_id: abcde

I get this message from Postman:
"type": "missing_oauth_payload",
"message": "A valid payload (OAuth2Payload | OAuth1Payload) is required to proceed with the request."

My Postman setup:
https://www.postman.com/lunar-module-candidate-37328496/workspace/pizzly-demo/collection/16011321-ce0fde4f-1a06-4b88-8ff1-c996df76ae62?ctx=documentation

I checked through the docs and couldn't find a similar example for generating a new authId using Google Sheets API v4.

Any help would be much appreciated. Thanks !

I'm able to connect fine using my settings at Google's testing tool:
https://developers.google.com/oauthplayground/

I'm just not sure how to do the same using Pizzly via post.

Any feedback/help would be much appreciated !
