Aha I see so the pagination is not working properly in Postman.
Do you have a swagger-page for the API where you can see exactly what is needed to paginate properly for the specific API? If not sensitive you can share it with me and I can have a look.
When just looking at the JSON-payload it seems like you are only fetcing the first 2 pages, with a maximum of 10 objects per page. It’s difficult to know however without the documentation.
