Access Token expires after one hour when we are using Named Credentials in salesforce.

[ayub1]

I have created an OAuth Provider and Named Credentials in salesforce, I am able to get voice call data from zoom contact center using Access Token, but my AccessToken gets expired after a one hour.

Error : -  {"code":124,"message":"Access token is expired."}

Request: -  System.HttpRequest[Endpoint=callout:Zoom_Credential/contact_center/voice_calls?from=2025-01-06T13%3A00%3A07Z&to=2025-01-07T13%3A00%3A07Z&page_size=100, Method=GET] 

Thanks
