customer.updated
Fortress POSTs this payload to the URL configured for your subscription. See Webhooks for delivery, signing and retry rules, and the event page for when it fires.
Payload
Unique identifier for this event. Stable across delivery attempts, so consumers must dedupe on this value. Also sent as the X-Fortress-Event-Id header.
What happened, in resource.action form. Also sent as the X-Fortress-Event-Type header. New values are added over time.
ISO-8601 UTC timestamp of when the event occurred, not when it was delivered. A retried delivery carries the original occurredAt.
Present, and true, only on a sample sent by the webhook trigger. A real delivery never carries it. It sits inside the signed body, unlike the X-Fortress-Test-Event header, so decide on this field.
