happyfox

happyfox_add_private_note

Add an internal note (never sent to the contact), optionally alerting agents and changing status, priority, assignee, due date or tags. HappyFox: POST /api/1.1/json/ticket/<ticket_number>/staff_pvtnote/.

happyfox_add_staff_reply

Add an agent reply to a ticket and/or change its status, priority, assignee, due date or tags. The contact is emailed ONLY if update_customer is true (HappyFox default: false). With no message it just updates properties. Moving to a completed status may require the category's compulsory custom fields. HappyFox: POST /api/1.1/json/ticket/<ticket_number>/staff_update/.

happyfox_create_contact

Create a contact. HappyFox treats this as create-or-edit keyed on email: if the email already exists that contact is updated, and any contact custom field NOT passed is reset — use happyfox_update_contact to edit an existing contact. HappyFox: POST /api/1.1/json/users/.

happyfox_create_ticket

Open a new ticket on behalf of a contact (created if the email is new). Needs a category id (a public category), a subject and a message in `text` or `html`. HappyFox: POST /api/1.1/json/tickets/.

happyfox_get_ticket

Fetch a ticket with its full conversation: status, priority, category, contact, assignee, custom fields, SLA breaches and every update (messages, private notes, property changes, attachment links that expire in 5 minutes). HappyFox: GET /api/1.1/json/ticket/<ticket_number>/.

happyfox_list_kb_articles

List the saved reports (id, name, description) from the Reports module. HappyFox: GET /api/1.1/json/reports/.
