Why is my access token for API calls suddenly disabled?

Hi All,

We are using one access token of our Shopify account in one of the Aggregator account since Oct-22. It was working perfectly fine. Today (17-Aug-23) we starts getting below error in API calls.

{
"errors": "[API] API Access has been disabled"
}

Will anyone please confirm if is there any duration for each token?
If not, then what can be the possible problem behind that? Also, We subscribed to some webhook with the same API Credentials those webhooks are working but not API.

Thanks in advance.
