Everything a developer needs

RESTful API

Predictable resources, JSON payloads and clear error codes. Anything you can do in the UI, you can do via the API.

Real-time webhooks

Receive events the moment they happen — deal created, deal won, invoice paid — with retries and signature verification.

OAuth2 & API keys

Secure authentication with scoped tokens, OAuth2 flows for third-party apps and revocable keys.

Idempotent requests

Retry safely without duplicate records, thanks to idempotency keys on every write operation.

Bulk & pagination

Cursor-based pagination and bulk endpoints to sync large datasets efficiently.

Rate limits & quotas

Generous limits, clear headers and a dashboard to track your usage in real time.
