What Is a Webhook? How It Works for Product Data Updates

Chris Johnson

Appliance, furniture, and mattress retailers often manage hundreds or even thousands of SKUs across multiple manufacturers. Each product can have its own specifications, dimensions, pricing, status, images, and other details, making it a significant part of catalog management to keep product information organized.
An Application Programming Interface (API) provides a way for one software system to request data from another. For retailers, a Product Data API can provide structured manufacturer product information directly into their systems, rather than requiring teams to manually collect and organize every product detail from separate sources.
Using a Product Data API can solve much of the data collection problem, but keeping the catalog current is a different challenge. Manufacturers add new models, update existing products, change pricing, or discontinue SKUs. Once the data is already in your system, another question appears: how does your system know when something has changed?
One option is to keep checking the API every few minutes. Many of those requests may return the same information because nothing new has arrived yet. Webhooks offer another approach: they send an update when a supported event occurs, so your system knows when there is actually something new to process.
What Is a Webhook and Why Your Business Needs It
A webhook is an automated Hypertext Transfer Protocol (HTTP) callback that sends data to another system when a supported event occurs. While a standard API request requires your system to request data, a webhook automatically sends an update to your registered endpoint.
Product catalogs in appliance, furniture, and mattress retail show why webhooks matter. Manufacturers regularly add new models, update product information, change pricing, change product status, or remove products from the catalog. Webhooks help your system stay aware of those changes. Without a webhook, your system may need to check those updates repeatedly.
Imagine a mattress manufacturer changes the status of one model from “Active” to “Discontinued”. Before activating the webhook, your system needs to check the data source every few minutes to see whether anything has changed. With a webhook, your system is notified and receives an update when the status changes. Your system then knows which product was affected and can process the new information.
The same approach can be used for other supported events, such as a new appliance being added, an existing furniture product being updated, or pricing information changing. The retailer still decides what happens after the update is received, but the system no longer has to keep asking whether there is something new to process.
How Does a Webhook Work?
A webhook follows a simple process from the moment product data changes to the moment the retailer receives the update.
A Product Change Happens
A supported change occurs, such as a new product being added, an existing product being updated, a price changing, or a product status changing.
The Data Source Detects the Update
The system that provides the product data recognizes the supported change and prepares the relevant information for transmission.
A Webhook Event Is Sent to Your Endpoint
The webhook sends the event to the URL registered for your system. The event includes information related to the product change.
Your System Receives the Update
Your system receives the webhook payload with the relevant product information. The update is then ready to be processed according to your workflow.
You Decide What Happens Next
After receiving the update, you decide how to handle the new information. You can apply it right away, review it first, or process it through your existing workflow.
How Do Webhooks Improve Product Data Updates?

Once a webhook is in place, the biggest change is not just how quickly product data can be updated. It also changes how often a retailer’s system needs to look for updates in the first place. Instead of repeatedly checking whether something has changed, the system can wait until new information is available to process.
That difference can make product data easier to manage, especially for retailers working with large catalogs and several connected systems. From staying aware of product changes sooner to reducing unnecessary API requests, webhooks can support a more efficient update process.
Faster Awareness of Product Changes
Retailers don’t have to wait for the next scheduled check to learn that something changed. When a supported event occurs, such as a product being discontinued, updated, or repriced, the retailer's system can receive the update sooner and decide how to process it.
Fewer Unnecessary API Requests
Without webhooks, a system may repeatedly check an API only to receive the same information it already has. Webhooks reduce unnecessary checks by sending an update only when there is something new to process.
Stay in Control of How Updates Are Applied
Receiving a webhook does not mean every change has to go live immediately without a double-check process. Retailers can decide whether to apply the new information right away, review it first, or process it through their existing workflow.
A Better Chance to Keep Pricing Competitive
Picture a shopper comparing several stores before buying a refrigerator. If one retailer still shows an older price while a competitor or manufacturer has already updated theirs, the retailer may appear more expensive and lose the shopper.
With a webhook, the retailer's system can receive pricing changes sooner, giving the business a better chance to keep its online pricing up to date and competitive.
