Hi everyone,

I’m encountering an invalid_grant error when requesting an access_token via /token. Here’s the workflow and failure point:

Token Request

POST: https://mymaindomain/token
Body (x-www-form-urlencoded):

grant_type: refresh_token  
client_id: <my_client_id>  
client_secret: <my_secret>  
refresh_token: <refresh_token>  *// From Client App redirect URL*  

Response:

{ "error": "invalid_grant" }  

SSO Flow Breakdown

1. Client (A): Sends refresh code → https://another_domain/sso (B)
2. Service (B): Redirects to →
   https://myinstance.imiscloud.com/Root_Folder/Folder_X/Page-Testing-SSO.aspx?code=<refresh_code_here> (C)
3. Page (C): Extracts code → Requests token from https://another_domain/page-sso?code=<refresh_code_here> (D)

Failure: Step (D) returns invalid_grant, blocking IQA lookup.

Troubleshooting Attempted

• Verified server timezone sync (no impact).
