Configure TeamCity to use a Webhook

Last Updated On

By default, TeamCity will use a pulling. It means that it will go to the VCS periodically and look for any updates. The standard setting is 60 seconds. However, it's not a best practice to use a pull, because:

  1. It produces unnecessary load on version control server.
  2. Long waiting period after each push. On average you should wait 30 seconds before TeamCity will notice the change and trigger a build. Having a delay with 30 seconds is infiniteness.

Starting from version 8.1 TeamCity ships with its own REST API. Basically, you need to send a POST request with the following format:


The URL above can be used to register a Webhook on each Repository push.

It's a good idea to create a separate user for this need.

Go to build configuration and set 


By settings up a Webhook, we were able to reduce the load on version control system server and save deployment time by having an immediate build triggering.
