Message data schema

Webhook messages are always sent as JSON payloads in the body of POST requests. The message is sent with Content-Type: application/json.

Regardless of the event category, the data in the message that is published to your endpoint follows the same schema:

    "timestamp": “<ISO formatted timestamp in UTC>”,
    "eventCategory": "<eventCategory>",
    "eventType": "<eventType>",
    "guid": "<eventGuid>",
    "details": {
        <eventType specific payload>

For reference information on the payload returned for specific event categories, see Webhooks reference.
