Adding a sub customer for quickbooks online php - php

Question

I can't seem to get this to work:
I have a parent company called
"XYZ Parent Company"
and a sub company called
"XYZ sub Company"
The Parent company exists in quickbooks already. I need to add the sub company with the parent know. I try this and it does not add the child only makes new customer. I am sure I am missing two things but I can't find what???
include 'blah blah directoty/example_app_ipp_v3/config.php';
// Set up the IPP instance
$IPP = new QuickBooks_IPP($dsn);
// Get our OAuth credentials from the database
$creds = $IntuitAnywhere->load($the_username, $the_tenant);
// Tell the framework to load some data from the OAuth store
$IPP->authMode(
QuickBooks_IPP::AUTHMODE_OAUTH,
$the_username,
$creds);
// Print the credentials we're using
//print_r($creds);
// This is our current realm
$realm = $creds['qb_realm'];
// Load the OAuth information from the database
if ($Context = $IPP->context())
{
// Set the IPP version to v3
$IPP->version(QuickBooks_IPP_IDS::VERSION_3);
$CustomerService = new QuickBooks_IPP_Service_Customer();
$Customer = new QuickBooks_IPP_Object_Customer();
$Customer->setName('99999');
//$Customer->setPhone('860-634-1602');
//$Customer->setEmail('keith#uglyslug.com');
$Customer->setCompanyName('XYZ Sub Company Name');
$Customer->setDisplayName('XYZ Sub Company Name');
$Customer->setFirstName('Bill');
$Customer->setLastName('Gates');
// Set the parent of the customer
$Customer->setParentFullName('XYZ Existing Parent Company Name');

Answer 1

This is incorrect:
// Set the parent of the customer
$Customer->setParentFullName('XYZ Existing Parent Company Name');
Per the QuickBooks API docs (http://developer.intuit.com/) you must specify the parent Id value to add a sub-customer underneath the parent customer. You can not specify the FullName (FullName isn't even a valid field name for the REST APIs, not sure where you got that from...).
You should be specifying:
$Customer->setParentRef(1234);
Where 1234 is the Id of the parent customer.
If you don't know the Id of the parent customer, you can query it like this:
$customers = $CustomerService->query($Context, $realm, "SELECT * FROM Customer WHERE FullyQualifiedName = 'your parent customer name here');
$Id = $customers[0]->getId();
