Subscribe to events with webhooks
Add a webhook subscription that sends calls, texts, voicemails and other events to your server.
Open Developer (owners and admins), tab Webhooks. Type your server's https address, choose how many days the subscription lasts, tick the events (finished calls, texts and test pings are ticked already; live call events, voicemails, faxes, presence and recordings are there too) and press Add webhook. Your server must echo the validation token. Copy the signing secret: it is shown once.
