# Adds health alerts for when events fail to generate

## What’s new

Adds the [v2.core.health.event_generation_failure.resolved](https://docs.stripe.com/api/v2/core/events/event-types.md?api-version=2025-11-17.preview#v2_event_types-v2.core.health.event_generation_failure.resolved) webhook event type. This event occurs when Stripe fails to generate events for your webhook endpoints and then resolves the issue.

## Why is this a breaking change?

This public preview includes several breaking changes from the private preview:

- Replaces the `related_object_id` with the [related_object](https://docs.stripe.com/api/v2/core/events/event-types.md?api-version=2025-11-17.preview#v2_event_types-v2.core.health.event_generation_failure.resolved-related_object) hash, which contains `id`, `type`, and `url` properties. This makes it easier to retrieve related objects.
- Removes the `missing_delivery_attempts` property. If your integration depends on this value, remove that dependency.
- Since [livemode](https://docs.stripe.com/api/v2/core/events/event-types.md?api-version=2025-11-17.preview#v2_event_types-v2.core.health.event_generation_failure.resolved-livemode) already exists at the top level of the [Event](https://docs.stripe.com/api/v2/core/events/object.md?api-version=2025-11-17.preview) object, this release removes the `livemode` property from the [impact](https://docs.stripe.com/api/v2/core/events/event-types.md?api-version=2025-11-17.preview#v2_event_types-v2.core.health.event_generation_failure.resolved-data-impact) hash. Update how your integration reads the property.

- The [context](https://docs.stripe.com/api/v2/core/events/event-types.md?api-version=2025-11-17.preview#v2_event_types-v2.core.health.event_generation_failure.resolved-context) property replaces the `account` property. Update your integration to use `context` instead of `account`.

These changes ensure that the alert more consistently follows the standardized structure of other [thin events](https://docs.stripe.com/event-destinations.md#events-overview) and simplify reading the related object.

## Impact

You can now subscribe to the `v2.core.health.event_generation_failure.resolved` webhook event to receive notifications when Stripe resolves event generation issues for your webhook endpoints. You can use this to proactively monitor and [troubleshoot webhook delivery problems](https://docs.stripe.com/webhooks.md#debugging).
