I need to request all invoices within a quarter, and return and sum the amount of each line item grouped by the line items account. However, no matter how I build the request the line items array is empty.
I am using the calcinai/xero-php library and have a working mockup that returns the data I expect it to:
private static function getBillsPaid($xeroClient) {
// ... some setup
$bills = $xero->load(\XeroPHP\Models\Accounting\Invoice::class)
->where('Type', \XeroPHP\Models\Accounting\Invoice::INVOICE_TYPE_ACCPAY)
->where('Status', \XeroPHP\Models\Accounting\Invoice::INVOICE_STATUS_PAID)
->where("Date >= DateTime($start)")
->where("Date <= DateTime($end)")
->execute();
$billsByAccount = new Map();
foreach ($bills as $bill) {
$invoice = $xero->loadByGUID(\XeroPHP\Models\Accounting\Invoice::class, $bill->getInvoiceID());
foreach ($invoice->getLineItems() as $lineItem) {
$billsByAccount->addListItemSum(
$lineItem->getAccountCode(),
$invoice->getCurrencyCode(),
$lineItem->getUnitAmount()
);
}
}
return $billsByAccount->getAll();
}
This works, however, it has to make a new request to load the line items for each invoice. What I need is for all the information to be loaded in a single request ($bills) so that it doesn't throw a "too many requests" error.
I have looked at the documentation and in theory adding a summaryOnly=True query to the request should resolve the issue I am facing.
However, adding ->setParameter('summaryOnly', 'true') to the request causes it throw a "bad request" error unless I remove both date queries from the request. But, even if I do remove the date queries it still doesn't include the line items.
For reference, when not fetching the $invoice, I am trying to get the line items from $bills->getLineItems().
What am I missing?
Can you try adding the page param e.g. ?page=1
