Overview

Extensiv Brand Manager is designed to help brands consolidate inventory, manage listings, and streamline orders across multiple marketplaces and sales channels. This DIY Developer Guide for Extensiv Brand Manager provides a clear, actionable framework for building secure, scalable, and efficient custom integrations with ERP, eCommerce, and fulfillment platforms.


Prerequisites for Extensiv Brand Manager Integrations

  • Extensiv Brand Manager API access credentials
  • API Key and Secret or OAuth 2.0 setup
  • Familiarity with:
    • RESTful APIs
    • OAuth 2.0 Authentication
    • JSON data structures
  • Tools: Postman, Extensiv API Documentation, SDKs (Node.js, Python)

Step 1: Authentication for Extensiv Brand Manager Integrations

Extensiv Brand Manager APIs use OAuth 2.0 authentication.

Authentication Example:

POST https://auth.extensiv.io/oauth/token
Content-Type: application/x-www-form-urlencoded

grant_type=client_credentials
&client_id=YOUR_CLIENT_ID
&client_secret=YOUR_CLIENT_SECRET

Use the access_token received in the Authorization header for subsequent requests.


Step 2: Endpoint Discovery and Data Mapping

Common API Resources:

  • Products and Listings
  • Orders
  • Inventory
  • Channels
  • Fulfillment Updates

Process:

  • Review Extensiv Brand Manager API documentation thoroughly.
  • Map your external system fields (e.g., SKU, Channel ID) to Extensiv data fields.

Important considerations:

  • SKU normalization across multiple marketplaces
  • Handling multiple warehouse and channel configurations
  • Properly formatting order and inventory data

Step 3: Building Integration Workflows

Integration Patterns:

  • Inbound (to Extensiv): Push inventory updates, product listings, and shipment data.
  • Outbound (from Extensiv): Pull order information, channel status, and stock levels.

Example: Updating Inventory

POST /api/inventory/update
{
  "sku": "SKU12345",
  "availableQuantity": 100
}

Example: Fetching Orders

GET /api/orders
Authorization: Bearer YOUR_ACCESS_TOKEN

Step 4: Error Handling and Pagination

Error Handling:

  • Capture all HTTP status codes and Extensiv Brand Manager-specific error details.
  • Implement retry mechanisms for rate limits (429) and server errors (5xx).

Pagination:

  • Use pagination parameters such as page and pageSize to manage large datasets.

Example:

GET /api/orders?page=2&pageSize=100

Step 5: Testing and Validation

  • Test each endpoint with Postman and Extensiv’s sandbox environment.
  • Validate inventory syncs, product updates, and order retrieval workflows.
  • Stress-test large catalog updates and order spikes.

Step 6: Deployment and Security

  • Deploy integrations on secure cloud platforms (AWS, Azure, GCP).
  • Securely store API keys and tokens using secret managers.
  • Enforce HTTPS/TLS encryption for all API calls.
  • Implement real-time monitoring, error alerting, and transaction logging.

Step 7: Maintenance and Monitoring

  • Monitor Extensiv Brand Manager API release notes and status updates.
  • Set real-time alerts for integration failures.
  • Track synchronization success rates, order processing speeds, and inventory accuracy.

Optional Enhancements

  • Middleware integrations (MuleSoft, Celigo, Boomi) for complex automation.
  • Custom dashboards for channel performance and stock visibility.
  • Event-driven workflows using webhooks for immediate status changes.
