sbSDK 0.1.3

Async Python SDK for the ServiceBridge field service management API v4.5

ServiceBridge Python SDK

An async Python SDK for the ServiceBridge field service management API v4.5.

Features

• Async-first — built on aiohttp, fully async/await
• Typed responses — all responses are Pydantic models with IDE autocompletion
• Auto-pagination — large result sets are fetched automatically across pages
• Rate limiting — built-in token bucket enforcing 50 req/s and 60,000 req/hr
• Token management — session token cached for 24 hours, auto-refreshed on expiry
• 31 resource clients — full coverage of the ServiceBridge v4.5 API
• Custom fields — access via get() and indexing (customer.CustomFields.get("Old Meter No"))

---

Requirements

• Python 3.11+
• ServiceBridge API credentials (User ID + Password)

---

Installation

pip install sbSDK

For development (editable install from source):

git clone https://github.com/wilkcom/sbSDK.git
cd sbSDK
pip install -e ".[dev]"

Dependencies

Package	Purpose
aiohttp>=3.9	Async HTTP client
pydantic>=2.0	Response models and validation
python-dotenv>=1.0	.env file support

---

Configuration

Credentials can be provided via environment variables or passed directly.

Option 1 — Environment variables (recommended)

Copy .env.example to .env and fill in your credentials:

API_USER_ID=your_user_id
API_PASSWORD=your_password

The SDK loads .env automatically on import.

Option 2 — Pass credentials directly

client = ServiceBridgeClient(user_id="your_user_id", password="your_password")

---

Quick Start

import asyncio
from servicebridge import ServiceBridgeClient

async def main():
    async with ServiceBridgeClient() as client:
        # List all customers (auto-paginated)
        customers = await client.customers.list()
        for customer in customers.Data:
            print(customer.FirstName, customer.LastName)

asyncio.run(main())

Always use ServiceBridgeClient as an async context manager (async with). This ensures the underlying HTTP session is properly opened and closed.

If you need to manage the lifecycle manually:

client = ServiceBridgeClient()
await client._api.__aenter__()
# ... do work ...
await client.close()

---

Response Types

Every method returns a typed Pydantic envelope. There are three types:

Type	Used for	Key fields
ApiResponse[T]	Single item (GET by id, POST, PUT)	.Data → one object
ApiListResponse[T]	Lookup/reference data	.Data → list of objects
ApiPagedListResponse[T]	Large entity lists	.Data → list, .TotalCount

All response objects also have .Status (int) and .Message (str).

result = await client.customers.get(customer_id=123)
print(result.Status)    # 200
print(result.Message)   # "OK"
print(result.Data)      # Customer object
print(result.Data.FirstName)

---

Custom Fields

Several resources (Customers, Employees, Inventory) return a CustomFields list from the API. The SDK wraps this in a CustomFieldMap that provides attribute-style access by stripping spaces from field names:

# API returns: [{"Name": "Old Meter No", "Value": "12345"}, {"Name": "Paid", "Value": "False"}]

customer = await client.customers.get(customer_id=123, include_custom_fields=True)

# Attribute access — spaces removed from name
print(customer.Data.CustomFields.OldMeterNo)   # "12345"
print(customer.Data.CustomFields.Paid)          # "False"

# Safe access with a default
val = customer.Data.CustomFields.get("OldMeterNo", "")

# Dict-style access
val = customer.Data.CustomFields["OldMeterNo"]

# Iterate all raw fields
for field in customer.Data.CustomFields:
    print(field["Name"], field["Value"])

The same works for employee.CustomFields and inventory_item.CustomFields.

---

Resource Reference

All resources are accessed as attributes on the client:

async with ServiceBridgeClient() as client:
    client.customers
    client.work_orders
    client.invoices
    # etc.

Standard CRUD pattern

Most resources support these methods:

# List all (auto-paginated, returns all pages)
result = await client.{resource}.list()

# Get one by ID
result = await client.{resource}.get({resource}_id=123)

# Create
from servicebridge.models import {Name}Create
result = await client.{resource}.create({Name}Create(Field1="value", ...))

# Update (full replace — API uses PUT)
from servicebridge.models import {Name}Update
result = await client.{resource}.update({resource}_id=123, data={Name}Update(Field1="new"))

# Delete
result = await client.{resource}.delete({resource}_id=123)

---

Resources

Customers

# List with optional filters
customers = await client.customers.list(
    nameFilter="Smith",
    branchFilter=5,
    includeInactiveCustomers=False,
    searchText="john",
)

# Get single customer (optionally with custom fields)
customer = await client.customers.get(customer_id=123, include_custom_fields=True)

# Create
from servicebridge.models import CustomerCreate
result = await client.customers.create(CustomerCreate(
    FirstName="Jane",
    LastName="Smith",
    Email="[e-mail]",
    Phone="555-1234",
))

# Update
from servicebridge.models import CustomerUpdate
result = await client.customers.update(123, CustomerUpdate(Email="[e-mail]"))

# Delete
await client.customers.delete(customer_id=123)

# Reactivate an inactive customer
await client.customers.make_active(customer_id=123)

# Retrieve saved payment methods
cards = await client.customers.payment_cards(customer_id=123)
bank_accounts = await client.customers.payment_bank_accounts(customer_id=123)

---

Work Orders

work_orders = await client.work_orders.list(statusFilter="Open", branchFilter=2)
wo = await client.work_orders.get(work_order_id=456)

from servicebridge.models import WorkOrderCreate, WorkOrderUpdate
result = await client.work_orders.create(WorkOrderCreate(
    CustomerId=123,
    LocationId=10,
    ScheduledDate="2025-04-01",
))
await client.work_orders.update(456, WorkOrderUpdate(Notes="Updated note"))
await client.work_orders.delete(work_order_id=456)

The WorkOrder model is fully typed and mirrors the complete API v4.5 response, including all nested objects and lists:

wo = await client.work_orders.get(work_order_id=456)
d = wo.Data

# Nested object access
print(d.Customer.Name)                    # "Acme Corp"
print(d.Customer.Id)                      # 123
print(d.Branch.Name)                      # "North Branch"
print(d.JobCategory.Name)                 # "HVAC"
print(d.SalesRepresentative.Name)         # "John Smith"
print(d.Contact.Email)                    # "[e-mail]"
print(d.GeoCoordinates.Latitude)          # 41.8781

# Custom fields
print(d.CustomFields.MyCustomField)       # attribute access

# Line items
for line in d.WorkOrderLines:
    print(line.Inventory.Name, line.Price, line.Quantity)

# Visits and team
for visit in d.Visits:
    print(visit.Date, visit.Team.Name)
    for member in visit.TeamMembers:
        print(member.FirstName, member.LastName)

# Attached documents
for doc in d.Documents:
    print(doc.Name, doc.Url)

# Metadata
print(d.Metadata.CreatedOn)
print(d.Metadata.CreatedBy)

# Photos sub-resource
photos = await client.work_orders.photos(work_order_id=456).list()

# Upload a photo
with open("photo.jpg", "rb") as f:
    result = await client.work_orders.photos(456).upload(
        file_content=f.read(),
        filename="photo.jpg",

---

Lookup / Reference Data

These resources are read-only and return small, unpaginated lists.

teams = await client.teams.list()
taxes = await client.taxes.list()
terms = await client.terms.list()
payment_methods = await client.payment_methods.list()
job_categories = await client.job_categories.list()
job_templates = await client.job_templates.list()
marketing_campaigns = await client.marketing_campaigns.list()
marketing_categories = await client.marketing_categories.list()
sales_reps = await client.sales_representatives.list()
statistics = await client.statistics.list()
accounts = await client.accounting.list_accounts()

---

Users

users = await client.users.list()
user = await client.users.get(user_id=1)

---

Reports

report = await client.reports.get(reportType="Revenue", dateFrom="2025-01-01")

---

Filtering and Query Parameters

All list() methods accept keyword arguments that are forwarded as query parameters. Use the parameter names from the ServiceBridge API docs:

# Date range filter
estimates = await client.estimates.list(
    dateFromFilter="2025-01-01",
    dateToFilter="2025-03-31",
    statusFilter="Open",
    branchFilter=2,
    teamFilter=1,
)

# Change tracking (delta sync)
customers = await client.customers.list(changeTime="2025-03-01T00:00:00")

# Search by external system ID
employees = await client.employees.list(externalSystemId="ERP-001")

---

Pagination

Pagination is transparent. When you call list(), the SDK automatically fetches all pages and returns the complete dataset — you never need to manage page numbers.

# This fetches ALL customers across all pages automatically
all_customers = await client.customers.list()
print(f"Total: {len(all_customers.Data)}")

The API returns up to 500 records per page. The SDK detects when a page is full and continues fetching until all data is retrieved.

---

Error Handling

The SDK raises typed exceptions for all error conditions:

from servicebridge import (
    ServiceBridgeError,   # base class for all SDK errors
    APIError,             # non-2xx HTTP responses
    AuthenticationError,  # 401 after token refresh fails
    NotFoundError,        # 404
    RateLimitError,       # 429
    ConfigurationError,   # missing credentials at startup
)

Example

from servicebridge import NotFoundError, APIError, ServiceBridgeError

async with ServiceBridgeClient() as client:
    try:
        customer = await client.customers.get(customer_id=999999)

    except NotFoundError:
        print("Customer not found")

    except RateLimitError:
        print("Rate limit hit — slow down requests")

    except APIError as e:
        print(f"API error {e.status}: {e.message}")
        print(e.raw)   # full raw response dict

    except ServiceBridgeError as e:
        print(f"SDK error: {e}")

Exception hierarchy

ServiceBridgeError
├── APIError(status, message, raw)
│   ├── AuthenticationError   # 401
│   ├── NotFoundError         # 404
│   └── RateLimitError        # 429
└── ConfigurationError        # missing credentials

---

Rate Limiting

The SDK automatically enforces ServiceBridge API limits:

• 50 requests per second
• 60,000 requests per hour

A token-bucket algorithm is used. If your code sends requests faster than these limits, the SDK will automatically pause (using asyncio.sleep) until a slot is available. You do not need to implement any throttling yourself.

---

Logging

The SDK uses Python's standard logging module under the servicebridge logger. To see debug output (token events, pagination progress):

import logging
logging.basicConfig(level=logging.DEBUG)

# Or target just the SDK logger
logging.getLogger("servicebridge").setLevel(logging.DEBUG)
