PushNotificationService

Chatto exposes this service below /api/connect.

Shared message and enum definitions are documented in Shared Types And Enums.

PushNotificationService

Browser Web Push subscription commands for the current user.

Subscribe

Stores or updates the caller’s browser push subscription.

The server must have Web Push configured. Clients normally call this after the browser grants notification permission and returns a PushSubscription.

POST /api/connect/chatto.api.v1.PushNotificationService/Subscribe

Input: SubscribePushRequest

Request to store a PushSubscription returned by the browser Push API.

Field	Type	Description
endpoint	string	Push service endpoint URL.

Result: SubscribePushResponse

Response from storing a browser push subscription.
