3CX Python SDK

A typed Python SDK for the 3CX XAPI (/xapi/v1), built on httpx and Pydantic v2.

Features

• OAuth2 client-credentials authentication with automatic token refresh
• OData v4 query builder ($filter, $select, $expand, $orderby, $top, $skip, $count)
• Automatic pagination — iterate over all pages with a single generator call
• Full coverage — 37 typed services covering every resource group in the 3CX XAPI swagger spec
• Auto-generated models — every Pydantic model is generated from swagger.yaml, giving you full IDE autocomplete on every field of every entity (User has 60+ typed fields, Queue has 50+, etc.)
• Reporting helpers for call log, queue performance, extension statistics, activity log, and more
• Context-manager support for clean resource management
• Escape hatches (client.get() / client.post()) for raw access to any endpoint

Installation

pip install 3cx-xapi-python-sdk

Quick start

from threecx import ThreeCXClient, ODataQuery

client = ThreeCXClient(
    base_url="https://pbx.example.com",
    client_id="<service-principal-client-id>",
    client_secret="<service-principal-secret>",
)

# ── Active calls ─────────────────────────────────────────────────────────────
for call in client.active_calls.list():
    print(f"{call.caller} → {call.callee}  (duration: {call.duration}s)")

# Drop a specific call
client.active_calls.drop(call_id=42)

# ── Users ─────────────────────────────────────────────────────────────────────
# List first 50 enabled users, sorted by extension number
q = ODataQuery().filter("Enabled eq true").order_by("Number").top(50)
for user in client.users.list(q):
    print(user.number, user.full_name, user.email)

# Get a single user and update their e-mail
user = client.users.get(101)
client.users.update(101, {"Email": "new@example.com"})

# Create a user
from threecx.models import User
new_user = client.users.create(User(
    Number="200",
    FirstName="Alice",
    LastName="Smith",
    Email="alice@example.com",
))

# ── Queues ────────────────────────────────────────────────────────────────────
for queue in client.queues.list():
    agents = client.queues.get_agents(queue.id)
    print(f"Queue {queue.name}: {len(agents)} agents")

# ── Call history ──────────────────────────────────────────────────────────────
q = ODataQuery().filter("CallDirection eq 'Inbound'").order_by("StartTime desc").top(100)
for entry in client.call_history.iterate(q):
    print(entry.start_time, entry.caller, "→", entry.callee, entry.status)

# ── Reports ───────────────────────────────────────────────────────────────────
from datetime import datetime, timedelta, timezone

end = datetime.now(timezone.utc)
start = end - timedelta(days=7)
rows = client.reports.get_call_log(start, end)
print(f"{len(rows)} call-log entries for the last 7 days")

# ── System status ─────────────────────────────────────────────────────────────
status = client.system.get_status()
print(f"PBX {status.pbx_version}  calls: {status.calls_active}  cpu: {status.cpu_usage}%")

# ── Context manager ───────────────────────────────────────────────────────────
with ThreeCXClient(base_url="https://pbx.example.com",
                   client_id="...", client_secret="...") as c:
    print(c.system.get_license())

OData query builder

from threecx import ODataQuery

q = (
    ODataQuery()
    .filter("LastName eq 'Smith'")
    .select("Id", "Number", "FirstName", "LastName", "Email")
    .expand("Groups")
    .order_by("Number")
    .top(25)
    .skip(0)
    .count()
)

All query parameters map directly to OData v4 syntax. Refer to the 3CX XAPI swagger for supported fields per endpoint.

Creating a service principal

1. Log in to 3CX as admin.
2. Navigate to Admin → Integrations → API.
3. Create a new service principal and copy the Client ID and Client Secret.

Services reference

The SDK exposes 37 services as attributes of ThreeCXClient, covering every resource group in swagger.yaml.

Calls & telephony

Users, groups & directories

Call routing & flow

Trunks & PBX hardware

Communication

System administration

Integrations

Reporting

Escape hatch

Any endpoint not covered by a typed service can be called directly:

data = client.get("/InboundRules", params={"$top": "10"})
result = client.post("/Backups/Pbx.CreateBackup")
