    first time invoice of xero developer is getting approve very easily, but if i have edited the invoice then it is not approving using php
    function approveInvoice($access_token, $tenant_id, $invoiceID) {
    $client = new Client();
    $url = 'https://api.xero.com/api.xro/2.0/Invoices/'; . $invoiceID;

    try {
    // Fetch the existing invoice details to get complete data
    $invoiceResponse = $client->get($url, [
    'headers' => [
    'Accept' => 'application/json',
    'Authorization' => 'Bearer ' . $access_token,
    'Xero-tenant-id' => $tenant_id,
    ],
    ]);

    $invoiceData = json_decode($invoiceResponse->getBody()->getContents(), true);

    // Ensure that the required fields are present
    if (!isset($invoiceData['Invoices'][0])) {
    return ['error' => 'Invalid invoice data fetched from Xero.'];
    }

    // Prepare the payload with the current invoice data and set status to 'AUTHORISED'
    $invoice = $invoiceData['Invoices'][0];
    $invoice['Status'] = 'AUTHORISED'; // Update the status to AUTHORISED

    // Create the payload retaining necessary fields
    $payload = [
    'InvoiceID' => $invoiceID,
    'Status' => 'AUTHORISED',
    'LineAmountTypes' => $invoice['LineAmountTypes'], // Ensure this is set correctly (e.g., 'Exclusive', 'Inclusive', 'NoTax')
    'Date' => $invoice['DateString'], // Ensure this date is in 'YYYY-MM-DD' format
    'DueDate' => $invoice['DueDateString'], // Ensure this date is in 'YYYY-MM-DD' format
    'Contact' => [
    'ContactID' => $invoice['Contact']['ContactID'] // Make sure this ID is accurate and matches an existing contact in Xero
    ],
    'LineItems' => array_map(function($item) {
    return [
    'Description' => $item['Description'],
    'UnitAmount' => $item['UnitAmount'],
    'TaxType' => $item['TaxType'],
    'LineAmount' => $item['LineAmount'],
    'Quantity' => $item['Quantity'],
    'AccountCode' => $item['AccountCode'] ?? '400', // Adjust with the proper account code
    'LineItemID' => $item['LineItemID'] // Include this if updating existing line items
    ];
    }, $invoice['LineItems'])
    ];

    // Log the payload
    error_log('Payload being sent to Xero: ' . json_encode($payload, JSON_PRETTY_PRINT));

    // Send the updated invoice data
    $response = $client->post($url, [
    'headers' => [
    'Accept' => 'application/json',
    'Authorization' => 'Bearer ' . $access_token,
    'Xero-tenant-id' => $tenant_id,
    ],
    'json' => $payload,
    ]);

    return json_decode($response->getBody()->getContents(), true);
    } catch (\GuzzleHttp\Exception\ClientException $e) {
    $responseBody = $e->getResponse()->getBody()->getContents();
    error_log('Error: ' . $responseBody);
    error_log('Error: ' . $e->getMessage());
    return ['error' => 'Failed to approve the invoice. Error: ' . $e->getMessage()];
    }
