# Publishing Your First Aggregation

Now that you have worked out how to write an aggregation query, you may sometimes want to publish this query to get live updates of your results. This can be useful if you are interested in identifying "trending" categories and to automatically update "hottest" categories.

To publish an aggregation, you will want to use the [publish aggregation](https://vectorai-development-api.azurewebsites.net/collection/publish_aggregation) endpoint. Publishing an aggregation means that the data is aggregated into a new collection. 

After you publish an aggregation, you may want to update the collection live. To do that, you wil want to use the `/collection/start_aggregation` endpoint. If you no longer want live updates and to update manually, you will want the `/collection/stop_aggregation` endpoint. 

Finally if you can delete a published aggregation by using the `/collection/delete_aggregation` endpoint.
