Get delivery metrics

Retrieve aggregated webhook delivery metrics for the authenticated seller.

Use this endpoint to monitor webhook reliability over time and detect delivery regressions across event types.

Query behavior:

• Accepts a 'range' parameter controlling how much historical data is returned.
• If omitted, the default range is used by the API.

Returned data is designed for dashboards and alerting workflows, including:

• Time-bucketed event series.
• Separation by webhook event type.
• Delivery outcome trends across the selected time window.

Recommended monitoring workflow:

1. Query metrics on a regular schedule (for example, dashboard refresh intervals).
2. Detect spikes in failures or drops in successful deliveries.
3. Pivot to /failures endpoints for endpoint-level investigation.
4. Re-run metrics after remediation to confirm recovery.
