Sending attachments using Mailjet

It would help if there were a node for:

Sending binary (base64 encoded) attachments using Mailjet node

My use case:

I use Mailjet’s transaction mail template to send invoices to clients. I have to fetch a dropbox link for the PDF and write the same on the body for the client to download it.

If an option to send binary data as an attachment on the Mailjet node is introduced (already present in the “Send Mail” core node), I could directly embed attachments of any kind into the mail.

Any resources to support this?

Mailjet supports posting base64 encoded attachments using their API. You can find their documentation here: https://dev.mailjet.com/email/guides/send-api-v31/#send-with-attached-files

Are you willing to work on this?

I can help in testing out.
