# Testing Webhooks

> Validate your webhook endpoint before processing live events

Before relying on webhooks in production, confirm your endpoint receives deliveries and verifies signatures correctly.

<CardGroup cols={2}>
  <Card title="Test Mode" icon="flask">
    All transactions made in Test Mode trigger real webhook deliveries to your
    subscribed endpoint
  </Card>

  <Card title="test.ping Event" icon="satellite-dish">
    Use the `test.ping` event from the dashboard to verify your endpoint is
    reachable and responding correctly
  </Card>
</CardGroup>

## Sending a Test Event

<Steps>
  <Step title="Subscribe in Test Mode">
    Create a webhook subscription pointing at your endpoint while in Test Mode.
  </Step>

  <Step title="Send a test.ping">
    From the dashboard, send a `test.ping` event to the subscription and confirm your endpoint returns a `200 OK`.
  </Step>

  <Step title="Verify the signature">
    Confirm your handler validates the `X-HostPay-Signature` against the subscription's signing secret. See [Security](/webhooks/security).
  </Step>

  <Step title="Trigger a real flow">
    Run a Test Mode payment or payout and confirm the matching event (e.g. `payment.succeeded`) is delivered and processed.
  </Step>
</Steps>

## Inspecting Deliveries

You can view delivery history — status, response code, latency, and the payload — for every attempt from the **Delivery Log** in the dashboard's Webhooks section.

<Tip>
  Failed deliveries can be manually re-triggered from the dashboard. See [Overview](/webhooks/overview) for the automatic retry policy.
