Explanation
Adobe Campaign allows you to send transactional emails with individual and/or personalized attachments using SOAP APIs. You can also create calculated attachments that can depend on the recipient and be converted to PDF.
To configure an email attachment on the fly to a transactional message, you need to define SOAP attachment parameters within the content of the delivery. These parameters are used to specify the URL, name, type and encoding of the attachment. For example, you can use <%= rtEvent.ctx.attachmentUrl %> to refer to the attachment URL.
