Hubble Cloud API Integration

Overview

Hubble Network connects off-the-shelf Bluetooth chips to a global network of 90M+ gateways. This skill helps you integrate with the Hubble Cloud API to manage devices, retrieve packet data, configure webhooks, monitor metrics, and manage your organization.

API Base URL: https://api.hubble.com

API Version: Rolling release with continuous deployment and backward compatibility

Domain Context

Key Concepts

Device: A Bluetooth-capable hardware endpoint registered on Hubble Network. Each device has:

•Unique device identifier (dev_eui)
•Device encryption keys for secure transmission
•Custom tags for organization and routing
•Platform-assigned tags (e.g., hubnet.platform: LoRaWAN)

Packet: Base64-encoded Bluetooth data transmitted by devices and received via gateways. Packets contain:

•Encrypted payload data
•Sequence numbers for ordering
•Authentication tags for verification
•Metadata (RSSI, SNR, gateway info, timestamps)

Webhook: HTTP endpoints you control that receive real-time packet data in batches. Key features:

•Push-based delivery (no polling required)
•Configurable batch sizes (10-1000 packets)
•Automatic retries on failure
•Delivery metrics for monitoring

Organization: Top-level entity containing devices, API keys, users, and webhooks. Organizations have:

•Unique organization ID (UUID)
•Multiple users with different roles
•API keys with granular scopes
•Billing and usage tracking

API Keys: JWT bearer tokens with 16 distinct authorization scopes controlling access to:

•Device management (read/write)
•Packet access (read)
•Webhook configuration (read/write)
•User management (read/write)
•Metrics and billing data (read)

Data Flow

•Device broadcasts Bluetooth packet
•Gateway receives and forwards to Hubble Network
•Platform processes and decrypts packet
•
Data available via:
- •Real-time webhooks (push notification)
- •API streaming (pagination with continuation tokens)
- •Metrics dashboard

Typical Use Cases

•Device onboarding: Register new IoT devices before deployment
•Packet retrieval: Stream historical or real-time packet data
•Webhook setup: Configure push notifications for packet delivery
•Fleet management: Tag, organize, and monitor large device deployments
•Metrics monitoring: Track API usage, packet volumes, webhook health
•Access control: Manage users and API key scopes

Authentication

Bearer Token Authentication

All API requests require a JWT bearer token in the Authorization header:

code

Authorization: Bearer <your-jwt-token>

Obtaining API Keys

•Log in to Hubble Dashboard
•Navigate to Developer → API Tokens
•Click Generate New Token
•Select required scopes (principle of least privilege)
•Copy and securely store the token

Important: API keys cannot be retrieved after creation. Store them securely.

Authorization Scopes

The API supports 16 distinct scopes for granular access control:

Device Management:

•devices:read - List and retrieve device information
•devices:write - Register, update, and delete devices

Packet Access:

•packets:read - Query and stream packet data

Webhook Management:

•webhooks:read - List webhook configurations
•webhooks:write - Create, update, and delete webhooks

Organization Management:

•organization:read - View organization details
•organization:write - Update organization settings

User Management:

•users:read - List organization users
•users:write - Invite, update, and remove users

Invitations:

•invitations:read - List pending invitations
•invitations:write - Send and revoke invitations

API Keys:

•api_keys:read - List API keys
•api_keys:write - Create and delete API keys

Metrics:

•metrics:read - Access API, packet, webhook, and device metrics

Billing:

•billing:read - View invoices and usage data

Best Practice: Request only the scopes your application needs. For read-only integrations, use *:read scopes only.

Rate Limits

Rate Limit Policy

•Per-endpoint limit: 3 requests/second
•Organization-wide limit: 15 requests/second
•HTTP 429: Rate limit exceeded

Rate Limit Headers

Response headers indicate your current rate limit status:

code

X-RateLimit-Limit: 3
X-RateLimit-Remaining: 2
X-RateLimit-Reset: 1640000000

Handling Rate Limits

When you receive a 429 response:

•Read Retry-After header (seconds to wait)
•Implement exponential backoff (1s, 2s, 4s, 8s, ...)
•Use batch operations when available (e.g., batch device updates)
•Cache responses to reduce repeated requests
•Spread requests across time windows

Example exponential backoff:

python

import time

def make_request_with_backoff(func, max_retries=5):
    for i in range(max_retries):
        response = func()
        if response.status_code != 429:
            return response
        wait_time = 2 ** i  # Exponential: 1, 2, 4, 8, 16 seconds
        time.sleep(wait_time)
    raise Exception("Max retries exceeded")

API Endpoints Overview

The Hubble Cloud API provides 40+ endpoints organized into 9 categories. For complete endpoint documentation, see API_REFERENCE.md.

Device Management

•PATCH /api/org/{org_id}/devices/{device_id} - Update device metadata and tags
•PATCH /api/org/{org_id}/devices - Batch update up to 1,000 devices
•DELETE /api/org/{org_id}/devices - Batch delete up to 1,000 devices

Key features:

•Batch operations: Create, update, and delete up to 1,000 devices per API call
•Auto-generated credentials: API generates device IDs and encryption keys
•Encryption options: AES-256-CTR, AES-128-CTR, or NONE
•Device management: Names, custom tags, platform tags, timestamp filtering

Packet Retrieval

Parameters:

•start_time / end_time - Time range (default 7 days)
•device_id - Filter by specific device
•platform_tag - Filter by tag (e.g., hubnet.platform=LoRaWAN)

Pagination: Uses Continuation-Token header for streaming large datasets

Packet Structure

The API returns packets with a nested structure. Understanding this structure is critical for extracting device information and metadata:

json

{
  "location": {
    "timestamp": 1765598212.181298,    // Unix timestamp (seconds)
    "latitude": 47.61421,
    "longitude": -122.31929,
    "altitude": 829,
    "horizontal_accuracy": 29,
    "vertical_accuracy": 29
  },
  "device": {
    "id": "bc17a947-7a4f-4cff-9127-340cc4005272",  // Device UUID
    "name": "Device Display Name",
    "tags": ["tag1", "tag2"],
    "payload": "SGVsbG8gV29ybGQ=",    // Base64-encoded
    "timestamp": "2025-01-15T10:30:45Z",
    "rssi": -85,                        // Signal strength (dBm)
    "sequence_number": 42,
    "counter": 123
  },
  "network_type": "bluetooth"
}

Important Field Locations:

•Device ID: packet.device.id (UUID format)
•Device Name: packet.device.name
•RSSI: packet.device.rssi (not at top level)
•Sequence Number: packet.device.sequence_number
•GPS Location: packet.location.latitude and packet.location.longitude
•Timestamp: packet.location.timestamp (Unix epoch in seconds)

Common Mistakes:

•❌ packet.device_id - Does not exist
•❌ packet.dev_eui - Does not exist at top level
•❌ packet.rssi - Does not exist at top level
•✅ packet.device.id - Correct way to get device ID
•✅ packet.device.rssi - Correct way to get signal strength

Helper Function Example:

javascript

function extractPacketInfo(packet) {
  return {
    deviceId: packet.device.id,
    deviceName: packet.device.name,
    rssi: packet.device.rssi,
    sequence: packet.device.sequence_number,
    location: {
      lat: packet.location?.latitude,
      lng: packet.location?.longitude,
      timestamp: packet.location?.timestamp ?
        new Date(packet.location.timestamp * 1000) : null
    },
    payload: packet.device.payload
  };
}

    response = requests.post(url, json=payload, headers=headers)

    if response.status_code == 200:
        data = response.json()
        devices = data.get("devices", [])
        print(f"Created {len(devices)} devices")
        return devices

Quick curl Example: List Devices

bash

curl -X GET "https://api.hubble.com/api/org/YOUR_ORG_ID/devices" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN"

Pagination

Continuation Token Pattern

For endpoints returning large datasets, the API uses continuation tokens instead of offset-based pagination:

•Make initial request to endpoint
•Process returned results (max 1000 items)
•Check response headers for Continuation-Token
•If present, make new request with Continuation-Token header set
•Repeat until Continuation-Token is absent

Example:

python

import requests

def stream_all_packets(api_token, org_id):
    url = f"https://api.hubble.com/api/org/{org_id}/packets"
    headers = {"Authorization": f"Bearer {api_token}"}

    all_packets = []
    continuation_token = None

    while True:
        if continuation_token:
            headers["Continuation-Token"] = continuation_token

        response = requests.get(url, headers=headers)
        data = response.json()
        all_packets.extend(data["packets"])

        continuation_token = response.headers.get("Continuation-Token")
        if not continuation_token:
            break

    return all_packets

Data Encoding

Base64 Encoding Requirements

Device Keys: Encryption keys are binary data and must be Base64-encoded for JSON transport:

python

import base64

# Binary key (32 bytes)
binary_key = b'\x1a\x2b\x3c...'

# Encode for API
encoded_key = base64.b64encode(binary_key).decode('utf-8')

# Decode from API response
decoded_key = base64.b64decode(encoded_key)

Packet Payloads: Similarly, packet payloads returned by the API are Base64-encoded:

python

# Decode packet payload
packet_payload_b64 = "SGVsbG8gV29ybGQ="
decoded_payload = base64.b64decode(packet_payload_b64)

Common Error: Forgetting to Base64-encode device keys results in 400 errors with message "Invalid deviceKey format".

Error Handling

For comprehensive troubleshooting, see TROUBLESHOOTING.md.

HTTP Status Codes

•200 OK: Successful request
•201 Created: Resource successfully created
•400 Bad Request: Invalid request format or parameters
•401 Unauthorized: Missing or invalid API token
•403 Forbidden: Insufficient scopes for operation
•404 Not Found: Resource does not exist
•429 Too Many Requests: Rate limit exceeded
•500 Internal Server Error: Server-side error (retry with backoff)

Common Error Patterns

401 Unauthorized:

•Missing Authorization header
•Expired or revoked API token
•Malformed token format

403 Forbidden:

•API key lacks required scope
•Attempting to access resources from different organization

400 Bad Request (Device Registration):

•Device key not Base64-encoded
•Missing required fields (name, dev_eui, device_key)
•Invalid device EUI format

429 Rate Limit Exceeded:

•Too many requests in time window
•Implement exponential backoff
•Check Retry-After header

404 Not Found:

•Invalid organization ID
•Device ID doesn't exist
•Webhook ID not found

Request Tracing

All responses include X-Request-ID header for debugging:

code

X-Request-ID: 550e8400-e29b-41d4-a716-446655440000

Include this ID when contacting support for faster issue resolution.

Best Practices

Security

•Never commit API keys to version control
•Store tokens securely (environment variables, secret managers)
•Use minimal scopes - Only request permissions you need
•Rotate keys regularly - Implement key rotation workflow
•Validate webhook tokens - Check HTTP-X-HUBBLE-TOKEN header

Performance

•Use batch operations - Update up to 1000 devices in single request
•Implement caching - Cache device lists, reduce repeated requests
•Stream with continuation tokens - Don't try to fetch all data at once
•Handle rate limits gracefully - Exponential backoff, not retry loops
•Use webhooks for real-time - Avoid polling for new packets

Data Handling

•Base64-encode binary data - Device keys and some payloads
•Validate data before API calls - Check formats locally first
•Handle pagination correctly - Use continuation tokens, not offsets
•Set appropriate time ranges - Default 7 days, adjust as needed
•Store device keys securely - Encryption keys are sensitive

Monitoring

•Track API metrics - Use /api/org/{org_id}/api_metrics
•Monitor webhook health - Check delivery success rates
•Set up alerting - For failed webhooks or API errors
•Log request IDs - Include X-Request-ID in application logs
•Track rate limit usage - Monitor X-RateLimit-* headers

Error Recovery

•Implement retry logic - With exponential backoff
•Handle partial failures - In batch operations
•Log all errors - With context and request IDs
•Graceful degradation - Fall back to cached data
•Alert on repeated failures - Don't silently fail

Webhook Validation

Webhook Request Format

Hubble sends POST requests to your webhook endpoint:

http

POST /your/webhook/endpoint HTTP/1.1
Host: your-domain.com
Content-Type: application/json
HTTP-X-HUBBLE-TOKEN: your-webhook-secret

{
  "packets": [
    {
      "device_id": "device123",
      "payload": "SGVsbG8gV29ybGQ=",
      "timestamp": "2024-01-15T10:30:00Z",
      "metadata": { ... }
    }
  ]
}

Validating Webhook Requests

Always validate the HTTP-X-HUBBLE-TOKEN header to prevent spoofing:

python

from flask import Flask, request, abort

app = Flask(__name__)
WEBHOOK_SECRET = "your-webhook-secret"

@app.route('/webhook', methods=['POST'])
def handle_webhook():
    # Validate token
    token = request.headers.get('HTTP-X-HUBBLE-TOKEN')
    if token != WEBHOOK_SECRET:
        abort(403)

    # Process packets
    data = request.json
    packets = data.get('packets', [])

    for packet in packets:
        process_packet(packet)

    return '', 200

Webhook Response

•Return 200 OK for successful receipt
•Hubble considers 2xx status codes as success
•Non-2xx responses trigger automatic retries
•Retries use exponential backoff
