Webhooks are HTTP calls (callbacks) that our server makes to yours when an important event occurs asynchronously (e.g., a quote was approved or paid).

Registering an endpoint

To receive webhooks, expose a POST route on your server (e.g., https://api.yourcompany.com/webhooks/cord).

1. Turn on Developer mode (the switch at the bottom of the Settings index) and open the Webhooks tab in the Developers dock, the bar at the bottom of the screen.
2. Add your URL and save. The signing secret is shown only once: store it.
3. Select which events to subscribe to.

Available events

Cord emits quote lifecycle events and, separately, events for the invoice as its own object (see Invoicing and the API):

• quote.sent — sent to the customer.
• quote.viewed — the customer opened it.
• quote.approved — the customer approved it.
• quote.rejected — the customer rejected it.
• quote.updated — it was edited and resent.
• quote.expired — it expired without a response.
• quote.deleted — a draft was deleted.
• quote.paid — it was paid in full.
• payment.partial — a deposit, balance, or installment was collected without covering the full total.
• payment.failed — a recurring charge failed.
• invoice.finalized, invoice.sent, invoice.paid, invoice.payment_failed, invoice.voided, invoice.marked_uncollectible, invoice.overdue — lifecycle of an invoice created as its own resource via /api/v1/facturas.

The body is JSON: { "id": "evt_...", "event": "quote.paid", "created_at": "...", "data": { "id", "folio", "status", "total", "cliente", "link_publico" } }. The event’s id is stable across retries and a manual redelivery from the dashboard — use it to deduplicate on your side.

Signature verification

Always validate the signature to ensure the event comes from Cord. Every delivery includes X-Cord-Signature-V1 (with a timestamp, replay protection) and, for backward compatibility, the legacy X-Cord-Signature (no timestamp). The event name travels in X-Cord-Event and its stable id in X-Cord-Event-Id/Idempotency-Key. On Node, the @flouviahq/elements/server package validates both forms for you (CordWebhooks.constructEvent); if you’d rather verify it by hand in any language, see the verification code.

Retries and inspection

Each endpoint keeps a delivery log (status, latency, and response for every attempt). If a delivery fails, you can redeliver it from the dashboard, and use the Test button to send a test event.
