Update Purchase Order

To update purchase Order pass the values to Invoice wrapper along with PurchaseorderId (Xero identifier) and assign it to request.xeroInvoice and then call the method BreadwinnerAPI.call().

Sample Code

try{
    bw_xero_api02.BreadwinnerAPI.RequestObject req = new  bw_xero_api02.BreadwinnerAPI.RequestObject();
    List<bw_xero_api02.Invoice> xeroInvoicesList = new List<bw_xero_api02.Invoice>();
    bw_xero_api02.Invoice xeroInvoice = new bw_xero_api02.Invoice ();
    xeroInvoice.PurchaseorderId = '5eac31f6-a05f-4a84-b3aa-47154c82afca'; // Required
    xeroInvoice.DueDate = string.valueof(system.today()+30);
    bw_xero_api02.Invoice.LineItemWrapper poLineItem = new bw_xero_api02.Invoice.LineItemWrapper();
    poLineItem.ItemCode = ''; 
    poLineItem.Description = 'li desc';
    poLineItem.UnitAmount = 500;
    poLineItem.Quantity = 3;
    poLineItem.AccountCode = '200';
    list<bw_xero_api02.Invoice.LineItemWrapper> poLineItemsList = new list<bw_xero_api02.Invoice.LineItemWrapper>();
    poLineItemsList.add(poLineItem);
    xeroInvoice.LineItems = poLineItemsList;
    xeroInvoice.ClientId = '39efa556-8dda-4c81-83d3-a631e59eb6d3';
    xeroInvoicesList.add(xeroInvoice);
    req.xeroInvoice = xeroInvoicesList;


    bw_xero_api02.BreadwinnerAPI.ResponseObject res =  bw_xero_api02.BreadwinnerAPI.call('updatePurchaseOrder', req);
    if(res.errors.size()>0){
        for(bw_xero_api02.BreadwinnerAPI.Error er :res.errors){
            System.debug(er); 
        }
    }
    system.debug('Updated PO' +res.XeroInvoices);
}catch(Exception ex){
    System.debug('Exception occurred while creating customers in Stripe.'+ex.getStackTraceString());
