DALP webhook event asset.issuance.retracted reference

An asset issuance event was retracted because a reorg invalidated the source log.

Delivery contract

Field	Value
Event type	`asset.issuance.retracted`
Version	`1`
Lifecycle state	`retracted`
Counter-signed receipts	No event-specific advice
SDK type	`Webhook.AssetIssuanceRetractedV1`

This row gives advice only. DALP waits for a counter-signed receipt only if the webhook endpoint's counterSignedReceipts value is true when DALP queues the delivery. When the value is false, a normal 2xx response completes the delivery.
