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
`market_id`	string (uuid)	Yes
`resolution_source`	string · nullable	No
`resolved_at`	string (date-time) · nullable	No
`status`	string · nullable	No
`winning_outcome_id`	string (uuid) · 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.
