Server-to-Server Webhooks

SignalRelay Pro allows your WordPress site to receive conversion events directly from third-party services through a signed REST Webhook endpoint.

---

Ingest Endpoint

SignalRelay exposes the following secure REST endpoint:

POST https://yoursite.com/wp-json/signalrelay/v1/webhook
Content-Type: application/json
X-SignalRelay-Signature: <secret_signature>

Sample Webhook Payload

{
  "event_name": "Purchase",
  "event_id": "booking_984712",
  "custom_data": {
    "value": 450.00,
    "currency": "USD",
    "content_name": "Beach Villa Booking"
  },
  "user_data": {
    "email": "guest@example.com",
    "phone": "+14155552671"
  }
}

Upon receipt and signature validation, SignalRelay immediately applies SHA-256 PII hashing and dispatches the conversion to all enabled ad platforms.
