Webhooks & integrations

Push GigBook events (inquiries, contracts, payments, planning) to Make.com, n8n, or Zapier with token-authenticated webhooks — keep Monday and your other tools in sync.

GigBook can POST a JSON event to your own endpoints whenever something happens — a new inquiry, a signed contract, a payment, a completed planning form, an updated event. Point those at Make.com, n8n, or Zapier and GigBook becomes the source of truth while your other tools (like Monday.com) stay in sync automatically — no double entry.

Set one up

In Settings → Webhooks & integrations, add your endpoint URL (e.g. a Make.com custom webhook). GigBook generates a secret token for that endpoint — it's sent in the X-GigBook-Token header on every request, so your receiver can require it and reject anything that doesn't match. Use Send test to fire a ping and confirm it works; recent deliveries (with HTTP status) show at the bottom of the page.

Events

Every endpoint receives all event types — branch on the type field in your automation.

Payload

Each delivery is a JSON body:

{
  "id": "…",
  "type": "payment.paid",
  "created_at": "2026-07-01T18:20:00.000Z",
  "org_id": "…",
  "data": { "event_id": "…", "payment_id": "…", "label": "Deposit", "amount_cents": 50000 }
}

With these headers:

• X-GigBook-Token — your endpoint's secret token (see below)
• X-GigBook-Event — the event type
• X-GigBook-Delivery — a unique id for this delivery

Confirm it's really from GigBook

Every request includes your endpoint's secret token in the X-GigBook-Token header:

X-GigBook-Token: <your token>

On your receiver, check that this header matches your token and ignore anything that doesn't — that's the whole check, no signatures or crypto. Keep the token secret, use an HTTPS endpoint, and rotate the token any time from the settings page.

Make / n8n / Zapier

• Make.com — add a Custom webhook trigger, paste its URL into GigBook, and route on the type field (e.g. inquiry.created → create a Monday item). To verify the token, add a step that only continues when the incoming X-GigBook-Token header equals your token.
• n8n — a Webhook node; compare the X-GigBook-Token header to your token.
• Zapier — Catch Hook trigger; filter on the X-GigBook-Token header + type.

Checklist

• Add your endpoint in Settings → Webhooks & integrations
• Send a test and confirm it arrives
• Require the X-GigBook-Token header on your side
• Branch on type and map fields into your tool (Monday, etc.)
