Question about subscription lifetime

Question

Hi Everyone,

We are creating a subscription to receive change notifications in chat and channel. In the documentation It says that the subscription expires in 3 days However while developing the bot we observed we are not receiving any change notifications after one hour. Is it because we are using a Microsoft sandbox account for development?

Thanks!

Hello @Kalinga Somana

Welcome to the community!

Yes, according to the documentation a subscription typically expires in 3 days.

However, expirationDateTime also determines how long the subscription will remain active. When creating a subscription, you set this value to indicate the duration for which you want to receive change notifications.

For example, if you set expirationDateTime to "2023-12-19T11:00:00.0000000Z", the subscription will be active until Dec. 19, 2023, at 11:00 AM (UTC).

Remember that if you request a subscription with an expirationDateTime more than 1 hour in the future, you must also subscribe to lifecycle notifications by including a lifecycleNotificationUrl property in your subscription request. This ensures that you receive notifications related to the subscription’s lifecycle events.
