Webhooks

Boursa delivers lifecycle events to your configured webhook URL via a transactional outbox (at-least-once, ordered per entity). Verify each delivery's signature and respond 2xx to acknowledge.

Events

Event	When
order.received	an order was accepted and reserved
order.filled / order.partially_filled	an execution booked
order.cancelled / order.expired / order.rejected	terminal outcomes
transfer.completed / transfer.failed	funding outcomes
fund_order.processed / fund_order.settled	fund order outcomes
report.ready / report.failed	a statement PDF finished

Each payload carries the entity id and its new state. Pending deliveries are visible at GET /v1/webhook-deliveries.

Reliability

Delivery is at-least-once — dedupe on the event/entity id. The platform retries failed deliveries with backoff. Because the outbox is written in the same transaction as the state change, you never miss an event for a committed change.
