`card.application.submitted`

Review status synchronized for an associated cardholder

When Emitted

When a channel supporting cardholder retrieval confirms approval, associated applications still in fulfillment are notified. data.status is the application’s actual progress, and cardholder_review_status is approved. This is not a successful card issuance event; do not resubmit the application or display the card as available because of it. Retrieve GET /v1/cards/applications/{data.id} after receiving it.

Payload Fields

Field	Type	Description
`id`	string	Use this for deduplication. `evt_…` remains unchanged when the same event is redelivered.
`type`	string	Always `card.application.submitted`
`created_at`	string	Time the event was created (RFC3339), not its delivery time. It is unchanged on redelivery.
`data.object`	string	Object type; determines which endpoint to query with `data.id`
`data.id`	string	Object ID; use it to retrieve details.
`data.status`	string	Treat unrecognized values as unknown and raise an alert; do not fall back to “processing”
`data.status_version`	number	Monotonically increasing; use it to discard older states that arrive late.

Signature Verification and Deduplication

Verify the signature against the raw request body bytes. Do not parse and reserialize the JSON: your JSON library may change key order or whitespace, which changes the signature and can look like a key configuration error.

// Node · Run before parsing JSON
const raw = await readRawBody(req);            // Buffer / string; do not use parsed req.body
const expect = crypto.createHmac("sha256", WEBHOOK_SECRET).update(raw).digest("hex");
const got = req.headers["z-signature"];        // Format: t=<unix>,v1=<hex>
if (!timingSafeEqual(expect, parseV1(got))) return res.status(400).end();

// Deduplicate using the envelope id, not data.id
if (await seen(JSON.parse(raw).id)) return res.status(200).end();
