Ongoing Monitoring Webhooks

Ongoing Monitoring (AML) Webhook Event
Quadrata will emit a webhook event (HTTP Request) whenever there is a change to a passport's AML score. The payload for this request will contain both, the previous AML score, and the updated AML score, along with the associated wallet address.
Ongoing monitoring is a premium feature. Contact Quadrata at [email protected] to enable ongoing monitoring for your dApp.

Payload Structure

Webhooks are sent over HTTPS with a signature verification header. Each payload will include the following data:

Request Header

Each webhook request that Quadrata emits will contain a header signature that an integrating application can use to verify the authenticity of the message.
  • X-WEBHOOK-SIGNATURE - Base64 Encoded SHA384 request signature.
See Webhook Request Signaturefor more information on how to verify the webhook request signature.

Request Body

  • eventId - The UUID for the event that triggered this webhook
  • monitoring - JSON payload with the data that was monitored and the monitoring type (AML)
  • nonce - To ensure the signature is always unique
  • timestamp - Unix epoch representing the time when the notification was triggered
  • type - Representing the type of notification, MONITORING
  • walletAddress - Wallet address associated to the passport
Quadrata will attempt to deliver a webhook payload up to 3 times for each configured URI, if an HTTP response status code is returned outside of the 2xx range (200, 201, etc).
