Test a webhook

curl -X POST "https://test-api.kashier.io/v2/webhooks/string/test" \  -H "Content-Type: application/json" \  -d '{}'
{  "success": true,  "statusCode": 200,  "responseBody": "OK",  "latencyMs": 184}

Sends a signed sample payload to a webhook's configured URL so you can confirm the endpoint is reachable and your signature verification works — without waiting for a real event. The test delivery is recorded like any other delivery, but flagged isTest: true so it's distinguishable in your delivery history.
