-Pull request (PR) triggers cause a pipeline to run whenever you open a pull request, or when you push changes to it. In Azure Repos Git, this functionality is implemented using branch policies. To enable PR validation, navigate to the branch policies for the desired branch, and configure the [Build validation policy](../../repos/git/branch-policies.md#build-validation) for that branch. For more information, see [Configure branch policies](../../repos/git/branch-policies.md).
