After searching in the app itself, I ran accross an example filter perameter that worked. Here it is for future reference.
/**
* Filters
* @var array
*
* Example:
*
* array(
* ‘post_type’ => array(‘post’, ‘posttypetwo’),
* ‘terms’ => array(
* ‘category’ => array(
* ‘termone’, ‘termtwo’, ‘termthree’
* ),
* ‘other-taxonomy’ => array(
* ‘termone’, ‘termtwo’, ‘termthree’
* )
* )
* );
*
@kylephillips Are you able to assist with this? Thanks
