How SMS works in HappyFox

Once configured, the integration handles your text conversations:

  • Automatic ticket creation: Incoming SMS messages create a new ticket in your selected category.
  • Threaded conversations: All messages from the same contact are grouped into a single ticket thread.
  • MMS support: Attachments sent via MMS are preserved as ticket content.
  • Reply from HappyFox: Respond to SMS messages directly from the helpdesk interface without switching to JustCall.
