proxy.setClientId

Set the Business Unit client ID for WSProxy operations — allows parent BU scripts to operate on child BU data.

Syntax

proxy.setClientId({ ID: clientId });

Parameters

Name	Type	Required	Description
clientId	number	Yes	The MID (Member ID) of the target Business Unit

Examples

Operate on a child BU from parent

var proxy = new Script.Util.WSProxy();

// Switch context to child BU with MID 123456
proxy.setClientId({ ID: 123456 });

// All subsequent operations target the child BU
var result = proxy.retrieve("DataExtension", ["Name", "CustomerKey"]);
var des = result.Results;

Iterate over multiple BUs

var proxy = new Script.Util.WSProxy();
var businessUnits = [
    { name: "US", mid: 123456 },
    { name: "EU", mid: 234567 },
    { name: "APAC", mid: 345678 }
];

for (var i = 0; i < businessUnits.length; i++) {
    proxy.setClientId({ ID: businessUnits[i].mid });
    var result = proxy.retrieve("DataExtension", ["Name", "CustomerKey"]);
    Write(businessUnits[i].name + ": " + result.Results.length + " DEs<br>");
}

Notes

setClientId can only be used from a parent Business Unit or Enterprise account. Child BU scripts cannot use setClientId to access other BUs.

Find the MID for a BU in: Setup → Account Settings → Business Units → (select BU) → MID column.
