Im using jasper server rest api to run and download my reports. Im not able to find a way to
send the data that will fill the report as a JSON in the run report put request body. Does anyone
has some docs on how to do it?
I'd recommend downloading the latest version of Jaspersoft Studio, create a new Data Adapter in JRS to use a remote datasource. Here are some JSS tutorials http://community.jaspersoft.com/wiki/jaspersoft-studio-tutorials-archive and http://community.jaspersoft.com/wiki/xml-datasources-jaspersoft-studio
Here is an example using an XML API call http://community.jaspersoft.com/wiki/remote-xml-datasource the JSON one will be pretty similar.
