Amounts are positive integer minor units (1999 is $19.99) with an ISO 4217 currency; a refund is `type: "refund"` with a positive amount. Each event is idempotent on `event_id`: resending it with the same money is reported as `duplicate`, resending it with different money is `rejected`. Totals in the console only include events in the club's reporting currency. Revenue reported here does not award XP. ## OpenAPI ````yaml https://api.develop.fourdos.dev/openapi/partner.json post /v1/revenue openapi: 3.1.0 info: title: 4D OS Partner API version: 0.1.0 description: >- REST API for 4D OS partners. Authenticate with your organization API key: `Authorization: Bearer `. Requests and responses are JSON with `snake_case` field names. Errors share one envelope: `{ "error": { "code", "status", "message", "details"? } }`. Mutating endpoints that declare it accept an `Idempotency-Key` header so retries are safe.
