HaloPSA Ticket Management

Tickets are the core unit of service delivery in HaloPSA. The API uses array-wrapped payloads for all write operations (POST /api/Tickets with [{...}]). Status, priority, and ticket type IDs are instance-configurable -- always query /api/Status, /api/Priority, and /api/TicketType to get valid values.

Core API Operations

Create Ticket

POST /api/Tickets
Authorization: Bearer {token}
Content-Type: application/json

[
  {
    "summary": "Unable to access email - multiple users affected",
    "details": "<p>Sales team (5 users) reporting Outlook disconnected since 9am.</p>",
    "client_id": 123,
    "site_id": 456,
    "user_id": 789,
    "tickettype_id": 1,
    "status_id": 1,
    "priority_id": 2,
    "category_1": "Email",
    "agent_id": 101,
    "team_id": 5
  }
]

Get / Search Tickets

GET /api/Tickets/54321                                    # single ticket
GET /api/Tickets/54321?includedetails=true&includeactions=true  # with related data
GET /api/Tickets?client_id=123&open_only=true             # open tickets for client
GET /api/Tickets?search=email%20not%20working              # text search
GET /api/Tickets?page_no=1&page_size=50&orderdesc=true     # paginated

Update Ticket

POST /api/Tickets

[{ "id": 54321, "status_id": 2, "agent_id": 101 }]

Resolve with resolution note:

[{ "id": 54321, "status_id": 8, "resolution": "Cleared Outlook cache and repaired Office installation." }]

Add Action (Note / Time Entry)

POST /api/Actions

Internal note:

[{ "ticket_id": 54321, "note": "<p>Root cause: KB5034441 update.</p>", "actiontype_id": 0, "hiddenfromuser": true }]

Client-visible note with email:

[{ "ticket_id": 54321, "note": "<p>We've identified the cause and are working on a fix.</p>", "actiontype_id": 0, "hiddenfromuser": false, "emailto": "john@acme.com" }]

Time entry:

[{ "ticket_id": 54321, "note": "<p>Troubleshooting email connectivity.</p>", "timetaken": 30, "charge": true, "actiontype_id": 0, "agent_id": 101 }]

Attachments

POST /api/Attachment          # multipart/form-data: file, ticket_id, filename, isimage
GET  /api/Attachment?ticket_id=54321   # list attachments

Ticket Creation Workflow (with Validation)

1. Validate client -- GET /api/Clients/{client_id}. If not found: stop and report error.
2. Check active contract -- GET /api/ClientContract?client_id={id}&active_only=true. If no active contract: stop and notify, or proceed per org policy.
3. Search for duplicates -- GET /api/Tickets?client_id={id}&open_only=true&search={summary_keywords}. If duplicate found: link tickets via action note instead of creating new ticket.
4. Create ticket -- POST /api/Tickets with defaults: status_id=1, priority_id=3 (if unspecified).
5. Verify creation -- confirm response contains id. If 400 error: check required fields (client_id, summary, tickettype_id).
6. Route and notify -- assign team based on category/client config, send acknowledgment action.

Status Transition Validation

Before changing status, verify:

• To Resolved/Closed (8/9): resolution field is required. Warn if moving directly from New without In Progress step.
• To In Progress (2): agent_id should be assigned. Warn if missing.
• Any transition: query /api/Status to confirm target status is valid for your instance.

Best Practices

• Search before creating -- always check for duplicate open tickets for the same client
• Use hiddenfromuser: true for technical notes; keep client-facing notes professional
• Log time entries as work happens -- attach timetaken and charge to action notes
• Monitor SLA states proactively -- tickets with slahold=false approaching deadlinedate need escalation

Reference Files

• FIELDS.md -- complete ticket field reference (core, classification, assignment, timeline, SLA, contract fields)
• ERRORS.md -- API error codes and validation error resolution
• REFERENCE.md -- status codes, priority levels, action types, SLA states, status transition flow
