Integrations & Automation

Drive every capability from a documented REST API with code examples — provision numbers, place calls, send SMS, read records.

Receive an HTTP callback the moment anything happens on a call or message, so your systems react in real time.

Push call data to your backend, CRM or warehouse as it happens — no nightly export.

Query your own systems mid-call to personalise a flow with live data — an order status, a balance, a booking.

Sync calls and contacts with Salesforce, HubSpot, Google and Microsoft through secure, native connections.

Wire Callr into thousands of apps through Zapier, Make and webhooks — no engineering required.

Design call and message flows as Callr Actions scenarios — a declarative, YAML-based framework inspired by GitHub Actions — and ship changes without redeploying.

Follow a scenario step by step as it runs, in the Callr Console, to build and troubleshoot flows fast.

Upload and organise the audio your flows play — IVR prompts, hold music, announcements.

Connect the Callr MCP server to your AI coding assistant, so it builds against the API with the docs in context.
