GET request with JSON body in SugarCRM - json

Question

I'm using SugarCRM rest API, and according to the documentation, to get a set of records, I have to use /<module> GET endpoint and pass JSON in the body to filter the query.
First, is it even possible to have a body in a GET request ?
and how can I build this kind of request then ?
I'm using postman and tried to pass parameters as query strings but it's not possible though.

As far as I know you have to put everything in the query string, which might look different to what you'd expect.
Example for a request to /Users:
{
max_num: 100,
fields: ["first_name", "last_name"],
filter: [
{"user_name":"admin"}
{"status":"Active"}
]
}
Written as query string this request will look like this:
/rest/v10/Users?max_num=100&fields=first_name,last_name&filter[0][user_name]=admin&filter[1][status]=Active
Observations regarding the query string format:
There is no { or }, the values of the request object are placed directly in the query string
Key-Value pairs are assigned with =, and separated by & (instead of : and ,)
There are no " or ' quotes at all, strings are written without those
An array of values (here: fields) is just one assignment with all values separated by ,
An array of objects (here: filter) has one Key-Value pair per bottom value and uses [ and ] to indicate the "path" to each value. Using 0-based numerical indices for arrays
Notes
Keep in mind there are length limits to URL incl. query string. E.g. 4096 bytes/chars for Apache 2, if I remember correctly. If you have to send very elaborate requests, you might want to use POST /rest/v10/<module>/filter instead.
URL-escaped (usually not necessary) the example filter would look like this:
/rest/v10/Users?max_num%3D100%26fields%3Dfirst_name%2Clast_name%26filter%5B0%5D%5Buser_name%5D%3Dadmin%26filter%5B1%5D%5Bstatus%5D%3DActive
