How do I get BitBucket.org commits to trigger TeamCity builds?

How does one configure webhooks in BitBucket.org to trigger TeamCity builds?

What is TeamCity deployment?

TeamCity provides the Deployment type of build configuration. Build configurations which perform deploying to some environment can be marked with this type: these are usually build configurations that have snapshot or artifact dependencies on the builds whose results they deploy.

Use the TeamCity REST API:

Create a user on your TeamCity server with Run build permission

Create a new webhook on BitBucket to the prepared URL

http://username:[email protected]/httpAuth/app/rest/vcs-root-instances/commitHookNotification?locator=vcsRoot:(type:jetbrains.git,count:99999),property:(name:url,value:bitbucket.org/bitbucketusername/repo.git,matchType:contains),count:99999

Replace username,password with the user you just created
Replace teamcity.server.address, bitbucketusername and repo with your repo values,
