• Basic Authentication – Though less secure, it’s still supported by some legacy inventory management systems, using a username and password encoded in the request header.

Authenticating webhook requests helps prevent spoofing and ensures only trusted data is processed by the receiving system.

2. Endpoint Registration

To receive events, you must register a valid HTTPS endpoint with your inventory management system. This involves specifying:

• The URL that will handle the incoming events.
• Event types you want to subscribe to (e.g., inventory.updated, item.deleted, stock.low).
• Headers or metadata required for custom processing.

Some inventory management system software solutions provide a dashboard or API to manage and test webhook registrations.

3. Subscribing to Relevant Events

The efficiency of an inventory management system depends on choosing only the events that impact your operations. Key event categories include:

• Stock changes – Real-time updates for stock increments, decrements, or adjustments.
• Order updates – Notifications on new orders, cancellations, and fulfillment status.
• Product data updates – Changes to item attributes like SKU, pricing, or availability.

By narrowing down subscriptions, you reduce payload noise and improve system performance, especially for small businesses relying on a lean management inventory system.

4. Retry and Failure Handling

Robust webhook implementation includes retry logic for failed deliveries. Most inventory management systems allow configuring:

• Retry intervals and maximum attempts.
• Dead-letter queues for persistent failures.
• Logging of webhook events for debugging and auditing.

This ensures that no critical update is lost, improving the reliability of your inventory stock management system.
