Summer break or not, we keep shipping new features at Our highlight for this month is the release of the new webhook functionality, which makes it even easier to set up automated labeling workflows.

Introducing webhooks

Webhooks are automated messages sent to your server when something happens. You can use webhooks to subscribe to certain events on your account and automatically trigger reactions.

For example, you could set up a workflow such that when an image is labeled on, the label is copied to your own database immediately. This is especially useful for real-time applications, compared to listening for changes by periodically polling an API endpoint.

Other examples include sending a Slack message when someone creates an issue, triggering a prediction pipeline in Apache Airflow when a new image is added to a dataset or returning the result from a labeling job to your customer in real-time.

Find out how to enable webhooks in our docs, and let us know how you will be using this new functionality!
