Create a webhook

HTTPS endpoints only, 10 per owner. The response includes the signing secret ONCE — deliveries carry X-Easerix-Event and an HMAC-SHA256 of the raw body in X-Easerix-Signature ("sha256=<hex>"). Three delivery attempts with backoff; 20 consecutive failures auto-disable the hook.

curl -X POST "https://example.com/v1/webhooks" \  -H "Content-Type: application/json" \  -d '{    "url": "string"  }'

{  "webhook": {    "id": "string",    "url": "string",    "events": [      "string"    ],    "active": true,    "failureCount": 0,    "lastDeliveryAt": "2019-08-24T14:15:22Z",    "createdAt": "2019-08-24T14:15:22Z",    "secret": "string"  }}
