The Retrieve Submissions action is a little more complex than the others. It returns details about the submissions of a certain form.
The pageNr and pageSize POST parameters can be used to determine the pagination in cases of forms with many submissions. By default, pageNr is 0 and pageSize is 25. When stated explicitly, the pageSize value must be between 25 and 100.
pageSize represents the number of submissions displayed on one page.
pageNr multiplied by pageSize represents the number of the submission with which displaying will start.
The submissions in the output can be ordered by the sort parameter, which can have one of the following values: ASC or DESC. Submissions are sorted chronologically, in ascending order (oldest → newest) or in descending order (newest → oldest).
