Capabilities
What's under the hood
Every feature is designed to work together, giving you a complete system out of the box.
Function Calling
AI agents execute real-time actions during calls through REST API function calling. Book appointments, check inventory, update records, and process payments mid-conversation.
Webhooks
Receive real-time notifications for call events: started, completed, qualified, appointment booked. Push call data to any system that accepts webhooks.
CRM Integration
Sync call outcomes, transcripts, and qualification data directly to HubSpot, Salesforce, or any CRM. Keep your pipeline updated without manual data entry.
Calendar Booking
AI agents book directly into Google Calendar, Cal.com, or Calendly during calls. Prospects pick available slots and get instant confirmation without human intervention.
REST API
Full API access to manage agents, campaigns, contacts, and call data programmatically. Build custom workflows and integrate TopCalls into your existing tech stack.
Zapier & n8n
Connect TopCalls to 5,000+ apps through Zapier or n8n automations. Trigger campaigns from form submissions, update spreadsheets with call results, and more.
Use Cases
Built for real workflows
CRM-Driven Campaigns
Trigger outbound campaigns when leads enter a specific CRM stage. Call outcomes flow back to update deal status, add notes, and move prospects through your pipeline automatically.
Appointment Booking Workflows
AI agents check real-time calendar availability during calls and book confirmed appointments. Prospects receive instant email/SMS confirmations while your team gets notified.
Custom Business Logic
Use function calling to connect your AI agent to any internal system. Check order status, verify account details, process returns, or look up pricing during live calls.
