How to Create Formatted Issues in Bitbucket

[API test]

I'm using PHP to automatically create Issues in Bitbucket, but the formatting of the issues is not working. This JSON to create issues:

{"title":"$titulo","content":{"raw":" $titulo n **name:** $name **Test:** $test n **Location:** $location **pobox:** $pobox "}}

How can I do to format my issues?

For example: to make bold, italics and skip lines in the issues' texts.

I need help, please.

Thanks very much,

Does anyone know how I can create bold, italic text and skip lines?
