PUT API giving error message

[tsoct]

Hello all,

I created a REST Message to create and update the record of SN instance1 to SN instance2.

Information I am storing in instance2 including instance1.table.record.sys_id and I am attempting to Update the record in instance2 based on sys_id as a parameter.

My POST is working fine but PUT is giving me an error msg: {"error":{"message":"Method not Supported","detail":"PUT method not supported for API"},"status":"failure"}

Could you help to advise what could be the mistake? 

*note:sys_id is stored as u_correlation_id in instance2

REST Message:

PUT 

AFTER UPDATE business rule

(function executeRule(current, previous /*null when async*/ ) {

    var body = {
        "u_organization": gs.getProperty('instance_name'),
        "u_name": current.name.toString(),
    };
    try {
        var r = new sn_ws.RESTMessageV2('my Integration', 'Default PUT');
	r.setStringParameterNoEscape('u_correlationid',current.getUniqueValue());
        r.setRequestBody(JSON.stringify(body));

        var response = r.execute();
        var responseBody = response.getBody();
        var httpStatus = response.getStatusCode();
        
    } catch (ex) {
        var message = ex.message;
      
    }
})(current, previous);

Thank you Kirby. I need the sys_id to be dynamic and I've managed to achieve what I wanted with staging table and transform map.
