Question
Is there a limit to how many files my customers can attach to a ticket through the web form?
Answer
The web form utilizes linked attachments and as such, authenticated end-users can submit up to 500 attachment files and the size limitation for a single file is 50 MB, as described in this section: Attachment size limitations.
Unauthenticated end-users have a hard code limit of five attachments for each web form request as a spam prevention policy.
Note: Requests submitted anonymously may encounter attachment limitations.
