# On GitHub pull request review event

> Start an automation from any GitHub pull request review action.

`onGitHubPullRequestReviewEvent` exposes the broad `pull_request_review` webhook family for submitted, edited, and dismissed reviews.

```ts automations/watch-github-reviews.automation.ts theme={null}
import { automation } from "automate.ax"
import { onGitHubPullRequestReviewEvent } from "automate.ax/github"

export default automation("Watch GitHub reviews", () => {
  const event = onGitHubPullRequestReviewEvent()
  event.transform(({ action, pull_request, review }) => ({
    action,
    pullRequest: pull_request.number,
    review: review.id,
  }))
})
```

Optional static `account` defaults to the project binding. Returns `Signal<GitHubPullRequestReviewEvent>`, GitHub's typed review webhook union with `action`, `review`, `pull_request`, `repository`, and `sender`. The installation needs Pull requests read permission and repository access. Review comments on individual diff lines use a different GitHub webhook family and do not emit this trigger.
