I would like more information regarding Query parameters. The documentation is https://developer.atlassian.com/bitbucket/api/2/reference/resource/repositories/%7Busername%7D/%7Brepo_slug%7D/src?_ga=2.122763075.93748874.1519148404-1385639217.1515692170#post. Specifically I would like to add author and message parameters. I am making the REST API call using an HTTP Client. I thought I could add them them to the URI as a query string. That doesn't work. So, how can I add these parameters so that they are persisted.
