card.application.awaiting_bind

Physical card ready to bind

When Emitted

Emitted after the physical card reaches the user and the application enters awaiting_bind. Standard applications under downstream inventory mode automatically move to this state through an in-person handover after approval and entry into the fulfillment queue. Platform-direct fulfillment requires confirmation of an offline handover or a shipment marked as received by the user. data.id is the public card application ID, already prefixed with cap_. Retrieve GET /v1/cards/applications/{data.id}, then call POST /v1/cards/bind → POST /v1/cards/{id}/activate. This does not mean issuance is complete: the card is not activated, so do not present it as available. Neither shipped alone, while the card is in transit, nor pending_activation after binding emits this event. Successful activation still uses card.application.approved and card.status.updated. ⚠ Not emitted for platform-direct members.

Payload Fields

FieldTypeDescription
idstringUse this for deduplication. evt_… remains unchanged when the same event is redelivered.
typestringAlways card.application.awaiting_bind
created_atstringTime the event was created (RFC3339), not its delivery time. It is unchanged on redelivery.
data.objectstringObject type; determines which endpoint to query with data.id
data.idstringObject ID; use it to retrieve details.
data.statusstringTreat unrecognized values as unknown and raise an alert; do not fall back to “processing”
data.status_versionnumberMonotonically 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();
