URGENT: Visma connect invalid grant after expiration

[kashyap]

We are facing issue, Connect app setup with 180days expiration. That means refresh token remain same upto 180 days. After completing 180 days all API getting "invalid_grant". Also entry removed from My details > Access token list.

How can we handle this case without involving end user for reauth everything?

Hi,

If the refresh token has expired, you can request a new refresh token by using a POST request to the /connect/token endpoint.

Please review the “Refreshing Access Tokens” section on the following page:
Connect ecosystem Knowledge Base - Offline Access: Refreshing Access Tokens:  

If this does not help, please provide more information, and I will assist you further.

Need to check at visma side, I have called connect/token API every 5 minutes  before it getting expire of 1 hour.
No new refresh token get, this found on development and live app both.

This create serious issue of all users who already connected and now they need to re-authorize (consent flow) manually.

Had the same issue, use the sliding experation option so you can set the refresh token to unlimited:

We already following this.

We are sending

POST request on https://connect.visma.com/connect/token

with headers

Content-Type: application/x-www-form-urlencoded
Accept: application/json
Authorization: Basic base64_encode(client_id:client_secret)

With data
grant_type=refresh_token
refresh_token=current saved refresh token
client_id=app client id
client_secret=app client secret

Every time getting same refresh token. When we get new refresh token after expiration or near to expiration?
