Hi @Fab
The Gmail Send Email Zap action steps supports multiple attachments.

Hey Troy,
Yes it does. But as soon as I do it.

It renders an error.

So sth isn't working somewhere.
Cheers,
@Troy Tessalone Thx for the reply
I tried different tweaks, but all of them to no avail. Even with only one attachment, it doesn't work:

With one attachment, or two. With attachments as an array or not, separated with a comma, or not. Even with Line Items:

The troubleshoot error is always the same:

I reach a dead end here as "Unauthorized” isn't documented.
The only workaround that I found is to include the attachment links in the body of the email itself.
Have you tried that zap?
Cheerio,
@Fab
