The Orriven Developer API lets your own software do what the console does: create events, configure ticket types and prices, watch remaining capacity, register attendees, approve applications, mint redemption codes and record check-ins. It is the same data and the same rules as the console — capacity, lifecycles and approvals behave identically whichever door the change comes through.
The API is scoped to one Business Unit. An API key is generated inside a Business Unit and can only read and write that unit’s events — never another unit’s, never another organization’s. See API keys.

​
What you can do

Automations fire for API actions exactly as they do for console actions: a registration created over the API triggers your “attendee added” automation, an approval triggers the confirmation flow, an arrival check-in triggers the welcome flow.

​
Base URL and interactive docs

Every endpoint in these pages lives under /v1 on your Orriven API host. In the examples we write the host as $BASE:
The API describes itself: GET $BASE/openapi.json returns the full OpenAPI 3.1 specification (use it to generate a client in your language), and $BASE/docs serves an interactive reference where you can try every endpoint with your key.

​
Requests and responses

  • Requests and responses are JSON; send Content-Type: application/json on writes.
  • Timestamps travel as ISO 8601 with an offset (2026-09-01T09:00:00+08:00).
  • Money is an integer in minor units of the event’s currency (¥120.00 → 12000), tax-inclusive — the same convention as the console.
  • Every request carries your key: Authorization: Bearer <secret>.
  • The API is date-versioned: your key is pinned at creation, and every response echoes the effective version in the Orriven-Version header.
