At operation 1106, the subscription management component 116 can send an authorization indicator to third-party server(s) 154 associated with the third-party application. In at least one example, based at least in part on receiving the authorization indication from the application 140, the subscription management component 116 can send an authorization indicator (e.g., an access token) to the third-party server(s) 154 (which can indicate that the user, group, communication channel, direct message, board, etc. is authorized to receive notifications associated with the object and/or third-party platform). In some examples, the subscription management component 116 can send an indication of the object associated with the subscription, the user associated with the subscription, the group associated with the subscription, the communication channel associated with the subscription, the direct message associated with the subscription, the board associated with the subscription and/or the like to the third-party server(s) 154. In some examples, the subscription management component 116 can send an indication of the frequency at which notifications are to be received and/or other specified preferences to the third-party server(s) 154.
