Hi,

In step 1 when you used the Token api call to generate an access token, can you confirm that you've followed the steps in the guide for getting an access token for a service app?

https://developer.laserfiche.com/guides/guide_oauth-service.html

By following the guide, were you able to successfully use the oauth Token API and get an access token from the Token API response? (https://signin.laserfiche.com/oauth/swagger/index.html#/Token/Token_GetAccessToken )

To verify the access token is valid, are you able to decode the access token? This can be done by pasting it here https://jwt.io/. If you are able to successfully decode the access token, you should be able to see in the payload data information about your oauth application.
