Webhook

shows.created

A seller scheduled a show. Rehearsals aren't sent. Requires read:shows.

Headers

Unique ID of the event. Retries of a delivery send the same ID, so use it to deduplicate.
webhook-timestamp
Type: integerFormat: int64
required

When this delivery attempt was sent, as a Unix timestamp in seconds. Each retry sends a new timestamp.
webhook-signature
Type: string
required

Space-separated signatures, each v1, followed by the base64 HMAC-SHA256 of {webhook-id}.{webhook-timestamp}.{body}, keyed with your webhook secret.
