Once you have completed the ordering process, you will receive a confirmation email of your order. In this e-mail you will find a link to WeTransfer, where all necessary details have been entered, and all the information you need to manually create a WeTransfer link.
Creating a WeTransfer link is very easy. You go to wetransfer.com and fill in email@example.com as your recipient. As announcement you have to fill in your order number (this can be found in the confirmation email, e.g. ON1701234) and any comments regarding your file(s). Last step is to upload the files to WeTransfer and click on the "Transfer" button.
