# Generate PDF/A-3 Format

{% hint style="success" %}
It's not mandatory to generate a PDF/A-3 format. For storage convenience, you can opt or keep only the XML generated in the last step. However, if you need to embed the system-generated PDF invoice/credit note/debit note with the XML as a PDF/A-3, you may follow these steps.
{% endhint %}

1. QR Code Placement Preparation
   * Determine the precise X and Y coordinates on the page where you want to insert the QR code
   * Include these coordinates in your JSON payload along with size of QR. sample  JSON payload given below

     ```postman_json
         "Stackcue": {
             "documentType": "StandardInvoice",
             "stackcueComplianceIdentifier": "1a05b34a-096c-4d00-affd-95c56e7ad2db",
             "stackcueProductionIdentifier": "490d97cf-8638-44bd-b1b1-a12337e19f90",
             "qrX": 85,
             "qrY": 120,
             "qrSize": 150,

         },
     ```
2. JSON Payload Conversion

   * Convert the entire payload to Base64 format
   * Tag the converted payload as "data"
   * Include your PDF file in the JSON payload, tagged as "file"
