If you read the description for the pageSize field:
The number of results to choose per page. A value will be selected automatically if you do not supply a pageSize or if the pageSize is higher than the maximum allowed.
It seems this API is capped at 500 items per page. In this case no, you can’t get them all in 1 API call.
Well, if you can fix that (remove the cap size (i know is gonna be slower)) in the next update it would be really nice. Until then thank you for your fast response and keep up the good work…
You can’t fix what isn’t broken. This is most likely by design to ensure faster responses and avoid locking up a connection worker for too long. You must fetch each page by passing the page parameter.
