In Genesys Cloud CX, a notification channel remains active for 24 hours. If the channel is not renewed within this period, attempts to use it will result in a 400 error. To maintain an active channel beyond 24 hours, you must resubscribe to the topics before the channel expires. This can be achieved by sending aPOSTrequest to
/api/v2/notifications/channels/{channelId}/subscriptionswith an empty array as the body, effectively extending the channel's validity for another 24 hours. Implementing a recurring task to perform this resubscription every 23 hours is recommended to ensure continuous operation.
