For some projects, developers must squash their changes into a singular commit before nominatnig changes for integration. This is also the case before they build and test the change, so that the commit hash used to build is the same used for nomination.

With our increasing need to automate code, our automation needs API support to squash the changes that involve 10+ number of files otherwise the engineers end up with an unnecessary manual step of squashing the changes or have an interruption in the automation before they can build the changes.

Bitbucket Cloud supports a merge API call with a strategy specification. If support is added to Bitbucket Data Center, a temporary branch could be used to achieve the same result.
