Allison Voice API
Programmatic access to your organization's knowledge base, team, contacts, calls, bookings, and more. The core of what the dashboard exposes, callable from scripts, automation platforms (Zapier, Make, n8n), or your own code.
Getting Started
Generate your first API key, make your first call, and see the ten-minute path from zero to working integration.
Authentication
API key format, header usage, read vs write scopes, rotation, and the "never commit a key" checklist.
Rate Limits
What the 100/min read and 30/min write limits mean, how to read Retry-After headers, and recommended backoff.
Errors
Uniform error shape, status code conventions, common failure modes, and how to handle validation details.
Versioning
What v1 guarantees, what counts as a breaking change, and how we announce deprecations.
Webhooks
Real-time event delivery to your own services. Nine event types, HMAC-signed, with automatic retries.
API Reference
Every endpoint with request + response shapes, try-it-out console, and downloadable OpenAPI spec.
V1
Stable within the v1prefix. Read and write contacts, knowledge, team, locations, escalation rules, settings, and webhook subscriptions with an API key. Calls, bookings, orders, and integrations are read-only, apart from updating an order's status on a call. Subscribe to nine event types over outbound webhooks — HMAC-signed and automatically retried. Use any HTTP client, or connect through Zapier, Make, n8n, or similar platforms using their generic HTTP request modules.
