7		-GetTracking uses 4 params to help retrieve trackings in question.

9		-1. xpathExpression: read the IXpathExpression for more details ([[IXpathExpression>>https://ixpath.app/xwiki/bin/view/iXPath%20V3/IXpathExpression/]])
10		-1. fetchLinks : for optimization, you can choose the links you would like to fetch by sending the links needed separated by ';' , if your xpathExpression contains already the link, it can bypass this param. If you want to fetch all links - which is not recommended - you can put the value '$ALL'.
11		-1. limit: it defines the max number of tracking to retrieve. **it's optional. **(Optional)
12		-1. order: whether you want to order the list of trackings in a descending way or not by a certain key order. The default value is 'trkID' and it's optional as long as you fill in the limit value. (Optional)
