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.
