FlexOps Python SDK

Official Python SDK for the FlexOps multi-carrier shipping platform.

Installation

pip install flexops

Quick Start

from flexops import FlexOps

# API key authentication (recommended for server-to-server)
client = FlexOps(
    api_key="fxk_live_...",
    workspace_id="ws_abc123",
)

# Get shipping rates from all carriers
rates = client.shipping.get_rates({
    "origin": {"addressLine1": "123 Main St", "city": "New York", "stateProvince": "NY", "postalCode": "10001"},
    "destination": {"addressLine1": "456 Oak Ave", "city": "Los Angeles", "stateProvince": "CA", "postalCode": "90210"},
    "package": {"weight": 16, "weightUnit": "oz"},
})

# Create a label with the cheapest rate
label = client.shipping.create_label({
    "carrier": rates["data"][0]["carrier"],
    "service": rates["data"][0]["service"],
    "fromAddress": {
        "name": "Warehouse",
        "street1": "123 Main St",
        "city": "New York",
        "state": "NY",
        "zip": "10001",
        "country": "US",
    },
    "toAddress": {
        "name": "Customer",
        "street1": "456 Oak Ave",
        "city": "Los Angeles",
        "state": "CA",
        "zip": "90210",
        "country": "US",
    },
    "parcel": {"weight": 16, "weightUnit": "oz"},
})

# Track a shipment
tracking = client.shipping.track("9400111899223456789012")

Authentication

API Key (recommended)

client = FlexOps(api_key="fxk_live_...", workspace_id="ws_abc123")

Email / Password

client = FlexOps(base_url="https://gateway.flexops.io")
client.auth.login("user@example.com", "password")
client.workspace_id = "ws_abc123"

Direct Carrier Operations

Access carrier-specific endpoints when you need full control:

# USPS domestic label
label = client.carriers.usps.create_domestic_label({
    "imageType": "PDF",
    "mailClass": "PRIORITY_MAIL",
    "weightInOunces": 16,
    # ... full USPS payload
})

# FedEx rate quote
rates = client.carriers.fedex.get_rates({...})

# UPS tracking
info = client.carriers.ups.track({"trackingNumber": "1Z999AA10123456784"})

# DHL shipment
shipment = client.carriers.dhl.create_shipment({...})

Webhook Verification

from flexops import WebhooksResource

is_valid = WebhooksResource.verify_signature(
    payload=request.body.decode(),
    signature=request.headers["X-FlexOps-Signature"],
    secret="whsec_...",
)

Curl Quickstart

Every SDK method is a thin wrapper around the FlexOps REST API. If you want to verify the API before committing to the SDK — or you're integrating from a language we don't ship a SDK for — these curl invocations hit the same endpoints:

# Shop rates across all connected carriers
curl -X POST https://gateway.flexops.io/api/shipping/rates \
  -H "X-API-Key: fxk_live_..." \
  -H "Content-Type: application/json" \
  -d '{
    "origin": {"addressLine1": "123 Main St", "city": "New York", "stateProvince": "NY", "postalCode": "10001", "countryCode": "US"},
    "destination": {"addressLine1": "456 Oak Ave", "city": "Los Angeles", "stateProvince": "CA", "postalCode": "90210", "countryCode": "US"},
    "package": {"weight": 16, "weightUnit": "oz"}
  }'

# Create a label
curl -X POST https://gateway.flexops.io/api/workspaces/ws_abc123/shipping/labels \
  -H "X-API-Key: fxk_live_..." \
  -H "Content-Type: application/json" \
  -d '{
    "carrier":  "USPS",
    "service":  "PRIORITY_MAIL",
    "fromAddress": {"name": "Warehouse", "street1": "123 Main St", "city": "New York", "state": "NY", "zip": "10001", "country": "US"},
    "toAddress":   {"name": "Customer",  "street1": "456 Oak Ave", "city": "Los Angeles", "state": "CA", "zip": "90210", "country": "US"},
    "parcel":   {"weight": 16, "weightUnit": "oz"}
  }'

# Track a shipment
curl https://gateway.flexops.io/api/workspaces/ws_abc123/shipping/track/9400111899223456789012 \
  -H "X-API-Key: fxk_live_..."

# Cancel a label (via the unified carrier-agnostic endpoint)
curl -X DELETE https://gateway.flexops.io/api/v3.0/shipping/Usps/cancel/9400111899223456789012 \
  -H "X-API-Key: fxk_live_..."

Use an fxk_test_... key instead of fxk_live_... to hit the sandbox environment; mock carriers respond, no real charges, no real labels.
