    integration_code="YOUR_CODE",
    secret="YOUR_SECRET"
)

# Access any entity
tickets = client.entities.tickets
companies = client.entities.companies
projects = client.entities.projects

# Use specialized methods
ticket = tickets.create_ticket(
    title="Issue",
    description="Description",
    account_id=123
)

# Advanced queries
results = tickets.query_builder()
    .where("status", "eq", 1)
    .where("priority", "gte", 3)
    .order_by("createDate", "desc")
    .limit(100)
    .execute()
```
