Kallix integrations and API
Complete list of CRMs, calendars, telephony providers, messaging platforms and field-service tools that integrate with Kallix, plus the webhook and REST API for custom stacks.
Kallix integrates natively with 30+ tools across CRM, calendar, telephony, messaging and field-service categories, and has a public webhook + REST API for anything not on the native list. Our team wires the integration during onboarding; you don't need engineering time.
Each integration is a real connector, not just a webhook that creates a note. After every call the agent writes structured fields back to your CRM: call disposition, qualification data, next action, recording URL, transcript link, deal stage update. We map every field with you during onboarding and you can revise the mapping any time.
- HubSpot · Salesforce · Zoho · Pipedrive · GoHighLevel · Close · Freshsales
- Bi-directional sync: lead enrichment data flows both ways
- Field-level mapping configurable per agent
- Custom field mapping included in onboarding fee
Calendar awareness is what makes 'book a meeting' actually work. The agent reads live availability with sub-second latency, respects buffer rules and travel-time settings, and confirms the booking in front of the caller before ending the call.
- Google Calendar · Outlook · Calendly · Cal.com · Acuity
- Round-robin distribution across multiple reps
- Travel-time and buffer rules respected
- Reschedule and cancel via voice or follow-up message
Telephony is selected per region for cost and quality. India deployments default to Exotel for compliance and call quality; US deployments default to Twilio. You can bring your own provider: we've connected to RingCentral, 8x8, Aircall and custom SIP setups for enterprise customers.
- Twilio · Plivo · Exotel · Vonage · custom SIP
- Number provisioning in 60+ countries
- Local-presence dialing for cold outbound
- Carrier-grade reliability with redundant routes
The API and webhook layer is how customers build their own dashboards, trigger custom workflows, or pipe call data into BI tools. Docs are public, every endpoint is OpenAPI-described, and we ship a TypeScript SDK.
- REST API with OpenAPI spec
- Webhooks: call.started, call.ended, qualification.completed, escalation.triggered
- TypeScript SDK + Python client
- Zapier and n8n connectors for no-code automation
