What should we implement in the server in relation to audio/video calls?
You need to implement interfaces to integrate with LINE Planet Cloud. The callback APIs you need to implement for each call type are as follows:
- 1-to-1 call
- Notify callback (notify_cb): Callback API called by LINE Planet Cloud when connecting a 1-to-1 call
- 1-to-1 Call Event callback (on_call_evt_cb): Callback API called by LINE Planet Cloud when a 1-on-1 call ends
- Group call
- Group Call Event callback (on_gcall_evt_cb): Callback API called by LINE Planet Cloud when a participant joins or leaves
For specifications related to the callbacks, see Server callback specification.
Note that LINE Planet does not perform push integration. If your service uses a mobile push notification, you must also send push notifications and manage device push tokens. General topology illustrates the concepts related to sending push notifications.
