Decoding the PDF

The PDF is returned in Base64. Here's how to decode it:

JavaScript

const response = await fetch('/api/guias/etiqueta/URU030856', {
  headers: { 'Authorization': 'Bearer ' + token }
});
const json = await response.json();

// Decode Base64 to Blob
const pdfData = atob(json.data.pdf_base64);
const bytes = new Uint8Array(pdfData.length);
for (let i = 0; i < pdfData.length; i++) {
  bytes[i] = pdfData.charCodeAt(i);
}
const blob = new Blob([bytes], { type: 'application/pdf' });

// Open in new window
window.open(URL.createObjectURL(blob));

// Or download
const a = document.createElement('a');
a.href = URL.createObjectURL(blob);
a.download = json.data.filename;
a.click();

C#

byte[] pdfBytes = Convert.FromBase64String(response.Data.PdfBase64);
File.WriteAllBytes(response.Data.Filename, pdfBytes);

// Or return as FileResult in a controller
return File(pdfBytes, "application/pdf", filename);

PHP

$pdfContent = base64_decode($response['data']['pdf_base64']);
file_put_contents($response['data']['filename'], $pdfContent);

// Or display in browser
header('Content-Type: application/pdf');
header('Content-Disposition: inline; filename="' . $filename . '"');
echo $pdfContent;

tip

This label is ideal for internal documentation and filing. To stick on packages, use the Small Label.
