Google Drive API integration - request body - invokeurl

Hi,

I am accessing Google Drive API (documentation at https://developers.google.com/drive/api/v3/reference/files) through Zoho CRM. This is working fine, using commands like the following, which pull a Google Drive folder reference from the Contact, and returns a list of files inside that folder:

gdriveURL = "https://www.googleapis.com/drive/v3/files";
mapParameters.put("q","'" + Contact.get("gdriveextension__Drive_Folder_ID") + "' in parents and (name contains 'foo' or name contains 'bar') and trashed = false");
mapParameters.put("supportsTeamDrives","true");
mapParameters.put("teamDriveId","xxxxxxx");
fileList = invokeurl
[
url :gdriveURL
type :GET
parameters:mapParameters
connection:"googledrive19"
];

However, for some of the API functions, such as renaming files, information needs to be passed in the request body. So for example, the body needs to look like this:

{
"name":"newname"
}

How do I pass request body information, through the Zoho invokeurl command? (Using "files: someJSONThing" as may be implied by the Zoho docs at https://www.zoho.com/deluge/help/deluge-invoke-url.html doesn't seem to work.)

Thanks.
