Zoho Leave API invokeurl returns error code 7019 "Missing parameter(s) in the request"

Hi,

I executed this in Zoho Flow to update a Leave Record in Zoho People :-

========================================

UpdateLeaveRecord = invokeurl

[

url :"https://people.zoho.com/people/api/forms/json/leave/updateRecord"

type :POST

parameters:UpdateRecord.toMap()

connection:"internal--zohopeople"

];

========================================

I received the following reply :-

========================================

"response": {

"message": "Error occurred",

"uri": "/api/forms/json/leave/updateRecord",

"errors": {

"code": 7019,

"message": "Missing parameter(s) in the request"

"status": 1

}

========================================

An example of the parameters passed in this command (values removed) :-

========================================

{

	"customUpdateLeaveRecord_27": {
		"GCalID": "xxxxxxxxxxxxxxxxxxxx",
		"Employee_ID": "xxxxxxxxxxxxxxxxxxxx",
		"DayDetails": {
			"05-Jul-2021": {
				"LeaveCount": 0.5,
				"Session": 1
			}
		},
		"Leavetype.ID": xxxxxxxxxxxxxxxxxxxx,
		"From": "05-Jul-2021",
		"Unit": "Day",
		"ApprovalStatus": "Pending",
		"Daystaken": 0.5,
		"Reasonforleave": "",
		"TeamEmailID": "",
		"Leavetype": "No Pay Leave",
		"To": "05-Jul-2021",
		"Employee_ID.ID": xxxxxxxxxxxxxxxxxxxx,
		"DateOfRequest": "16-May-2021"
	}
}

========================================

I obtained the template for the keys and values for Leave record above by executing a GET command and following the formats exactly.

Anyone can assist to highlight what other parameters are required to update a Leave record successfully?

Thanks in advance!

Best regards,

Shahnan
