Webhook events


At Moov, we generate an event when something happens in our system. When an event occurs, we record the relevant data. For example, when a customer is created, we generate an event called customer.created. The contents of an event object depend on its type.

Here’s a sample event payload, with customer.created as an example.

  "eventID": "30f39f5b-6a26-4772-b5a5-d8148d2e7c8f",
  "type": "customer.created",
  "data": {
    "customer": {
      "customerID": "b6d8cc28a443ef03c1d45a3cdcd7dec4237ec1a8",
  "createdOn": "2021-03-10T03:07:19Z"
Key Type Description
type string Description of the event
data string Data associated with the event
eventID string Unique identifier for the event object
createdOn timestamp Timestamp for when event object was created

HTTP Delivery headers

Once a webhook event is sent to your endpoint, you will receive a delivery via HTTP POST with some unique headers. These headers are important for verifying that Moov (vs. a third party) sent the payload. For more information on verifying webhooks, see Check Webhook Signatures.

Here are the unique headers you can expect to see in a webhook event delivery.

Header Name Description
X-Signature Cryptographically generated hash to be checked against for security purposes
X-Timestamp Timestamp of the event delivery
X-Nonce One time use number for webhook signature verification
X-Webhook-ID Unique identifier for the delivery
