PDF Documents

Download Business Documents as PDF

With the Xentral API, you can easily download key business documents in PDF format. This allows you to export documents such as orders, invoices, or delivery notes directly from your application or system.

Supported Document Types

You can currently download the following document types as PDFs:

  • Sales Order (salesOrders)
  • Invoice (invoices)
  • Delivery Note (deliveryNotes)
  • Credit Note (creditNotes)
  • Purchase Order (purchaseOrders)
  • Return (returns)

How It Works

Downloading works via the respective VIEW endpoint of the document. Instead of requesting a JSON response, you simply set the Accept header to application/pdf to receive the raw PDF file.

Steps

  1. Send a GET request to the document’s VIEW endpoint.

  2. Set the following accept header:

    Accept: application/pdf

  3. The API will respond with a binary/raw PDF file, which you can save or use directly.

💡

Note: The Accept header must be set correctly. If it is missing or incorrect, the response will default to JSON.

Example: Download a Sales Order as PDF

Request

GET https://{xentralId}.xentral.biz/api/v1/salesOrders/12345
Accept: application/pdf
Authorization: Bearer <your_api_token>

Response

The response body contains the PDF in binary/raw format. Save it with the .pdf file extension.

Example using curl

curl -X GET \
  https://xentralId.xentral.biz/api/v1/salesOrders/12345 \
  -H "Authorization: Bearer YOUR_API_TOKEN" \
  -H "Accept: application/pdf" \
  --output sales_order_12345.pdf

More Examples

Download an Invoice

GET https://{xentralId}.xentral.biz/api/v1/invoices/67890
Accept: application/pdf

Download a Delivery Note

GET https://{xentralId}.xentral.biz/api/v1/deliveryNotes/45678
Accept: application/pdf

Download a Credit Note

GET https://{xentralId}.xentral.biz/api/v1/creditNotes/11223
Accept: application/pdf

Important Notes

  • The Accept: application/pdf header is required to receive a PDF.
  • The document ID ({id}) must be valid and accessible to your API user.
  • If the document is already sent/archived you will receive the archived PDF, otherwise the PDF will be generated on the fly.

Developer Tips

  • In API tools like Postman or Insomnia, you can manually set the Accept header and download the PDF directly.
  • In programming languages (e.g. Python, JavaScript, PHP), use a standard HTTP client to download and save the response as a .pdf file.
