get
Returns all segments for the profile as a JSON string.
This is a serialized version of segments with the same structure: a JSON array where each element contains the segment's id and name, e.g. [{"id":"...","name":"..."}].
Only use this method when you want to use it in combination with a BlueConic plugin (ex.: React Native, Flutter) that requires a serialized version of the segments.
Return
The segments as a JSON string.
