Attachments And Files

Handlet handles files in several contexts: customer message attachments, workspace uploads, and social media assets.

Principles

• Store files with account ownership metadata.
• Keep private customer material out of public buckets.
• Validate file type and size before accepting uploads.
• Keep attachment records linked to the conversation or workflow that uses them.

Customer messages

Provider attachments should remain associated with the canonical message and conversation. Do not assume every channel supports the same attachment metadata or delivery constraints.

Generated and uploaded media

Media used for social drafts or other workflows should be reviewable before it is published or sent.
