-Bitbucket Server will delete a SAST project **only when using the Post Webhooks plugin**.  The current implementation is limited in that:

+Bitbucket Server will delete a SAST project either using the PUSH webhook event or using the Post Webhooks plugin.  The current implementation is limited in that:
 
 * Project delete not work if using Config-As-Code given the settings for team and/or project name have been deleted from the branch.
 * Project delete will work if the project name is calculated or scripted and the team assigned to the project matches the default team in the CxFlow YAML configuration.

+**Bitbucket Cloud**
+
+Bitbucket cloud currently does not support deleting project in CxSAST when unprotected branch is deleted.
