# Webhook Notifications ## Receive Notification via Webhook Datasaur provides webhook to notify your application when an event happens in your labeling projects. Webhook is useful for automation in your Machine Learning project. For example, you can use webhook to feed the data directly into your model right after labelers finish their projects. To start using webhook, follow these steps below. 1. Create a webhook endpoint on your server. 2. Register the endpoint with Datasaur. For this you will need to contact . ### List of Events Datasaur provides a number of events that you can listened to and leverage. * Project Created * This event will be triggered when a new project is created. * Before Update Labels * This event will be triggered just before the labeler put a new label or update an existing label. * Project Completed * This event will be triggered when a Labeler toggles the project as completed in the Labeler Mode. * Project Reviewed * This event will be triggered when a Reviewer toggles the project as completed in Reviewer Mode. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
