Only 20 element as a json result in an http request

Only 20 element as a json result in an http request

Hello. I'm a user of CRM Plus. Every time I made a request though the API to get the contacts, leads or whatever, I obtain a maximun of 20 elements.

In the API documentation is written 200/100 is the maximun limit of elements in a request for accesing/modifying.

Any idea of what is happening?

Thanks in advance.
