Drazill API Documentation

Event schema version 2026-05-08. Delivered as the type field of the webhook envelope, signed with Drazill-Webhook-Signature.

Payload fields

The data object carries these fields. Money and quantity values are delivered as decimal strings. Fields beyond the structural IDs are optional because a producer legitimately omits them on some transitions.

Field	Type	Required
`average_fill_price`	number or string · nullable	No
`filled_quantity`	number or string · nullable	No
`market_id`	string (uuid)	Yes
`order_id`	string (uuid)	Yes
`outcome_id`	string (uuid) · nullable	No
`quantity`	number or string · nullable	No
`side`	enum(BUY, SELL) · nullable	No
`status`	string · nullable	No

Verify the signature before you act on a webhook, and treat it as a notification: re-read authoritative state from the REST API before moving money. See Signing & verification.
