Sending Your Signed Invoice to IRBM

Today we connect your Laravel app to the IRBM MyInvois API. You’ll submit your base64-encoded XML with the correct token, headers, and endpoint.

Step 1: Get Your Access Token

Make a POST request to IRBM’s OAuth endpoint:


$response = Http::asForm()->post('https://preprod-api.myinvois.hasil.gov.my/api/v1.0/token', [
  'grant_type' => 'client_credentials',
  'client_id' => env('IRB_CLIENT_ID'),
  'client_secret' => env('IRB_CLIENT_SECRET'),
]);

$accessToken = $response->json()['access_token'];

Add credentials to your .env file:


IRB_CLIENT_ID=your_dummy_id
IRB_CLIENT_SECRET=your_dummy_secret

Step 2: Encode and Prepare the Invoice


$signedXml = app(IRBXmlSignatureService::class)->sign($unsignedXml);
$encodedXml = base64_encode($signedXml);

Step 3: Post to the IRBM API


$response = Http::withToken($accessToken)->post('https://preprod-api.myinvois.hasil.gov.my/api/v1.0/invoices', [
    'invoice' => $encodedXml,
]);

if ($response->successful()) {
    return $response->json();
}

throw new \Exception('Failed to submit invoice: ' . $response->body());

Step 4: Handling the Response

The response will include:

✅ uuid
🕘 submissionDateTime
📦 invoiceStatus
🔗 Optional: invoiceLink or QR code data

Debug Tip

If your response fails, check:

✔️ Signature placement inside ext:UBLExtensions
✔️ Correct token and base64 format
✔️ That no raw XML is submitted (always base64-encoded)

Coming Up in Day 9

We’ll build a proper invoice submission service class, handle retries, and log failures for traceability — ready for real-world production handling.
