API Access: Testing Your Integration

How To
API Access

Testing

Each webhook endpoint’s page has a Send Test Event button. Clicking it sends a single delivery to your configured URL using the same thin payload shape shown in the Webhooks section, but with the event overridden to "test" — both in the X-Credlab-Event header and in the payload body’s event field:

X-Credlab-Event: test
{
  "event": "test",
  "credit_application": {
    "id": "ca_sample000000",
    "approval_status": "approved",
    "approval_decided_at": "2026-01-02T00:00:00Z"
  },
  "account_id": "acct_sample000000"
}

Use this to verify your receiver is reachable, that signature verification passes, and that your JSON parsing handles the payload shape correctly, before going live. Your receiver should treat any event type it doesn’t recognize (including test, and any future event types) as safely ignorable rather than erroring.
