‘ The API credentials used in a Pay call can make the Refund call
‘ against a payKey, or a tracking id, or to specific receivers of a payKey or
‘ a tracking id that resulted from the Pay call.

‘ A receiver itself with its own API credentials can make a Refund call against
‘ the transactionId corresponding to their transaction.
‘ The API credentials used in a Pay call cannot use transactionId to issue a refund
‘ for a transaction for which they themselves were not the receiver.

‘ If you do specify specific receivers, you must provide the amounts as well.
‘ If you specify a transactionId, then only the receiver of that transactionId
‘ is affected. Therefore the receiverEmailArray and receiverAmountArray should
‘ have 1 entry each if you do want to give a partial refund.

‘ (payKey and receiverEmailArray and receiverAmountArray) or

It will support only for https website.

using the below function you can get the querystring value using jquery

function getquerystring(sParam)

var sPageURL = window.location.search.substring(1);
var sURLVariables = sPageURL.split(‘&’);
for (var i = 0; i < sURLVariables.length; i++)

Convert Hexcode to RGB values

This answer has been taken from Stackoverflow which helped me to convert hex to rgb format.

the below function you can use to convert but pass hex values without ‘#’ and get RGB values

Hexcode = ‘#00000’;

call function like

hexToRgb(00000);

function hexToRgb(hex) {
var bigint = parseInt(hex, 16);
var r = (bigint >> 16) & 255;
var g = (bigint >> 8) & 255;
var b = bigint & 255;
return r + “,” + g + “,” + b;
}

Result : ‘0,0,0’
