VoiceInfra supports five connection methods. Choose the one that fits your system. 1. OAuth — for apps with native OAuth 2.0 flows (HubSpot, Google Calendar, Microsoft 365). Click Connect in Settings → Integrations and follow the guided authorization. 2. API Key — for REST API integrations (Salesforce, Stripe, Twilio, etc.). Paste your API key or token into the integration settings form. 3. MCP Server — connect any MCP-compatible tool for real-time in-call actions. Your agent calls the tool during the conversation and acts on the result immediately. 4. Custom Functions — define any REST API endpoint as a callable function. Your agent invokes it mid-call to fetch data or trigger actions, no custom code required on your side. 5. Webhooks — configure an HTTPS endpoint in your own system to receive a POST request with full call data every time a call completes.PBX and SIP integrations are handled separately under Settings → SIP & Numbers. See the SIP integration guide for details.
