## Webhook Configuration

When using a Git generator, ApplicationSet polls Git repositories every three minutes to detect changes. To eliminate
When using a Git generator, the ApplicationSet controller polls Git repositories every 3 minutes (this can be customized per ApplicationSet with `requeueAfterSeconds`) to detect changes. To eliminate
this delay from polling, the ApplicationSet webhook server can be configured to receive webhook events. ApplicationSet supports
Git webhook notifications from GitHub and GitLab. The following explains how to configure a Git webhook for GitHub, but the same process should be applicable to other providers.

```yaml
apiVersion: argoproj.io/v1alpha1
kind: ApplicationSet
metadata:
name: guestbook
namespace: argocd
spec:
goTemplate: true
goTemplateOptions: ["missingkey=error"]
generators:
- git:
# When using a Git generator, the ApplicationSet controller polls every `requeueAfterSeconds` interval (defaulting to every 3 minutes) to detect changes.
requeueAfterSeconds: 180
repoURL: https://github.com/argoproj/argo-cd.git
revision: HEAD
# ...
```

!!! note
The ApplicationSet controller webhook does not use the same webhook as the API server as defined [here](../webhook.md). ApplicationSet exposes a webhook server as a service of type ClusterIP. An ApplicationSet specific Ingress resource needs to be created to expose this service to the webhook source.
