Currently in Bitbucket Cloud, there is rest api to search a given code or text in a workspace which brings output based on commit file name and its content but not on commit message.
For ex. /2.0/workspaces/felisklera/search/code?search_query=IPA-3738
This API will bring result if IPA-3738 text is present in commit file name or the content of commit file or in any other entity but not bringing any result if this text is present on a commit message.
Therefore we need an API in Bitbucket Cloud which can search a given code or text in commit message.
