Adding attachments to transactional sends

You can attach the following file types to your transactional sends:

• PDF
• JPEG
• PNG

This means you can send files such as invoices, return labels, order summary, scannable QR codes, etc.

To do this, call the Transactional API adding attachments as a list.

Considerations

You must encode your file in base64. 

Be aware that if only one of your files fails, the entire call will fail.

• The file extension must be one of these:
  • .pdf
  • .png
  • .jpeg
  • .jpg
• Maximum of 10 files per message.
• Maximum file size: 10MB total attachment size
• All attachments should be saved with different names.
