Remarks

For getting all records at a time do not add Page in request header.

Use PerPage parameter to change maximum number of records per page during population of paginated data; by default, each page contains at most 10 records at a time.

Use header parameter Page only for getting the data of that particular page in which that Project is belonging (with the same filtration logic).
If request header contains Page then it will get the first preference for populating project list.
