#VanceTel API
VanceTel is a programmable phone system: a real softphone app with a production REST API, webhooks, deep links and an MCP server behind it. Use the API to send SMS and MMS, place click-to-call deep links, sync contacts, and react to inbound messages and call events. Everything your team sees in the softphone is also reachable from your own software.
The public API is write- and event-oriented: you create and send (messages, contacts, deep links) and you subscribe to webhooks for inbound activity. The softphone app surfaces the full conversation and call history in real time.
#Base URL
