# Inspect delivery attempts

<Snippet file="graphql/sdk-note.mdx" />

Each time Plain attempts to deliver an event to a webhook target, the result is recorded as a delivery attempt. This is useful for debugging failing webhooks programmatically — for example to surface a recent failure rate in your own observability tooling.

Each attempt records:

* the event ID and event type that was delivered
* when the attempt happened and how long it took
* the result, which is one of: a successful HTTP response, a failed HTTP response (4xx/5xx), an error (network failure), a rejection, or a schema validation failure

You can filter attempts by event types or by result status.
