In our application, after the branches are merged through the Pipeline, the rules in the branches are cleared but the branch is not deleted. We are left now with 1000+ empty branches. When i searched for the solution, I saw a post with the below answer, but the answer is not so clear. Not sure if this was working in Pega lower version, I cant find this method in Branch API. We use Pega 23.

To delete empty branches automatically, you can use the Pega API. You can create an activity that calls the `Branch` API and uses the `deleteBranch` method to delete empty branches. In the `deleteBranch` method, you can specify the branch name and the `deleteEmpty` parameter as `true` to delete empty branches. 

Here is an example of how to use the `deleteBranch` method in an activity:

``` Call Branch.deleteBranch with parameters: .BranchName = "BranchName" .deleteEmpty = true ```

You can then schedule this activity to run at a specific time interval to automatically delete empty branches.
