How to use dynamic attachment name

Question

we are sending transactional email with attachment via message center.

Currently we dont have connection to sftp the file to the adobe server before the sent, we try to upload the file to the google cloud storage and generate the signed url, then pass to the rtevent. However this is not working. (error message: Unreachable Inbound email bounce (rule 'Probably_unreachable' has matched this bounce))

We have tried using a public link such as https://host/file.pdf, and it works perfectly fine. however if we tried pass the url as https://host/file.pdf?test=test, the attachment name received in the email is "file.pdftest=test". below is our current attachment configuration.

The signed url will have long query parameters with the authentication headers, which i think why it cause the email to bounce.

so the question is, is there a way to customize the attachment name?

Sample url is something like this:

https://storage.googleapis.com/bucketname/sample.pdf?x-goog-signature=signature&x-goog-algorithm=GOOG4-RSA-SHA256&x-goog-credential=credential%40serviceaccount.google.copm%2F20201023%2Fnorthamerica-northeast1%2Fstorage%2Fgoog4_request&x-goog-date=20201023T165959Z&x-goog-expires=6000&x-goog-signedheaders=host

Hi @chiding,

You can also have a dynamic name to your attachment based on a value of a field from the request. e.g. <%= rtEvent.ctx.fileNameToShowInEmail %>

You need to go to the advanced tab of the "Attachment definition" window, and do the following. This way you can have a different name for every request.

Regards,
