REST API
Versioned endpoints for subscribers, lists, campaigns, automations, and events. Generous rate limits, idempotency keys, and typed SDKs in TypeScript and Python.
Signed webhooks
Subscribe to opens, clicks, bounces, complaints, list changes, and automation transitions. Every payload is HMAC-signed and retried with exponential backoff.
