token.corporate-action.announced
A corporate action cleared its approval and is scheduled to execute, so holders can expect the distribution or change. Carries identifiers and the action type only; read terms and holder amounts through the corporate-action API.
Delivery contract
| Field | Value |
|---|---|
| Event type | token.corporate-action.announced |
| Version | 1 |
| Lifecycle state | final |
| Counter-signed receipts | No event-specific advice |
| SDK type | Webhook.TokenCorporateActionAnnouncedV1 |
The receipt recommendation does not change delivery behavior. 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.

}TypeScript SDK example
Use the request's raw body and headers with your endpoint's webhook secret. This handler illustrates verification and event selection. Before writing downstream state, deduplicate deliveries by evt_id and recognize replayed outcomes by their domain identifiers.
const result = await verifyWebhook({
rawBody,
headers,
secret: process.env.DALP_WEBHOOK_SECRET!,
});
if (!result.ok) {
throw new Error(`Webhook verification failed: ${result.code}`);
}
if (result.event.type === "token.corporate-action.announced") {
const event: Webhook.Event<"token.corporate-action.announced"> = result.event;
console.log(event.payload);
}HTTP delivery example
This illustrative request shows the delivery shape. Its timestamp and signature are placeholders; a verifier rejects them. Use a signed platform delivery to verify your endpoint.

This page documents version 1 of token.corporate-action.announced. This event type is not deprecated. The DALP events manifest contains the machine-readable AsyncAPI entry.
primary-market.subscription.final
An investor paid into a token sale and bought tokens; sent once the chain finality watermark reaches its source block. The purchase is the subscription: no separate allocation event follows, and the tokens arrive with primary-market.delivery.final. Amounts are in each asset's base units.
token.corporate-action.completed
A corporate action finished executing and reached its terminal completed state.
