Connectivity without limits

Three pillars built on open standards.

Real-time webhooks

Get instant notifications for purchases, check-ins and promoter registrations at any endpoint. Exponential retries, HMAC signatures and at-least-once delivery.

High-availability REST API

Query attendees, merch inventory and finances programmatically. Cursor-based pagination, generous rate-limits and OpenAPI 3.1 self-documented schemas.

Bank-grade security

Encrypted, rotating API keys. Mandatory TLS 1.3, HMAC-SHA256 signatures on every webhook, granular scopes and full audit log on every call.

Native integrations
