I have a situation where I need to send an email when a pdf file attached, but we're not storing that file anywhere, what we're doing is having the API send the file as base 64 to the front-end for display and download, so I've been checking how the front-end could send the email with an attachment but I haven't found a way to do it Any of you have any idea how I could do it? or could you give us any recommendation please?
