Delta Feed

Rapid Product Catalog Updates

Export partner product data as frequently as you need. Without changing your existing system. Always up-to-date product information.

In the same format, but tens of times lighter

Can be updated every minute

Integration without developers in a couple of minutes

What is DeltaFeed?

A regular feed always contains the entire catalog. DeltaFeed only contains what has changed: new products, updated prices, stock levels. You save resources and speed up processes, while partners always work with current data.

You need a Delta Feed if

It is critically important to quickly synchronize prices with a partner

The server (website) cannot handle product catalog updates

You want to expand the product catalog without changing the website

You need to update prices on the site frequently

The business is growing, but you don't want to spend money on developers

New suppliers are emerging

How DeltaFeed solves the problem

We read the source feed and memorize its contents

1

On schedule (even every minute), DeltaFeed reads the feed again and records all changes—new products, price updates, and stock levels

2

We generate a delta feed containing only the changes. It can be received in the original format or in any of dozens of other formats

3

You choose how to retrieve the data—download a file, receive via API, or automatically send to partners

4

Retrieve data according to your convenient schedule, even once a minute

FAQ

Do I need a delta feed if I have a small catalog?
Yes, if you frequently update prices and stock levels. Even with hundreds of products, DeltaFeed saves time and eliminates routine work.
What if I have thousands of SKUs and huge price lists?
This is precisely the key scenario. DeltaFeed reduces the load on the system and speeds up the loading of even the 'heaviest' files.
Is it difficult to set up?
No. Setup takes a couple of minutes in the personal account. Developers are not required.
In what format will I receive the data?
In any format: in the original feed format or another convenient one (CSV, XML, YML, etc.).
How often can I update?
Even every minute. You choose the synchronization schedule yourself.
Can DeltaFeed be used without other NotPIM tools?
Yes. It works both separately and as part of the ecosystem, where it can serve as a link in full automation.
What happens if I miss one of the loads?
There are two scenarios. The first is that the system tracks what you have already received and, if a load is missed, provides more data (e.g., for 10 minutes instead of 5). The second is using a timestamp: you specify the period for which you need the data (5, 30, or more minutes), and you receive it without interruption.
How much does DeltaFeed cost?
There is a free plan—up to 500 unique products per month. This means if your catalog consists of 500 items, you can process them daily without limits. Detailed pricing is available in the "Pricing" section. https://notpim.com/en/price/.

DeltaFeed — the delta feed for automating product data

DeltaFeed (often written as delta-feed or delta feed) is an e-commerce tool that allows for the creation of special product feeds containing only catalog changes. Unlike a classic feed, where the entire list of products with all characteristics is exported every time, a delta feed shows only what has changed since the last export: new products, price adjustments, and stock updates. This approach significantly saves resources, speeds up synchronization processes, and makes working with large product matrices much easier.

Technically, DeltaFeed works on a comparison principle. In the first step, the system reads the source product feed and saves it as a benchmark. Then, at specified time intervals—whether every minute or once a day—the system re-accesses the same feed and records only the changes. These changes are compiled into a separate delta feed, which the client receives in a convenient format. This can be the original format (CSV, XML, YML) or any other format suitable for the requirements of a CMS, marketplace, or advertising platform. DeltaFeed allows for the complete exclusion of unnecessary data transfer, which is especially important for companies dealing with catalogs containing tens or hundreds of thousands of SKUs.

Why has the delta feed become such a sought-after tool? Primarily due to load. Imagine a store where prices for thousands of products change daily. If a full feed of 200 megabytes is uploaded every time, it leads to delays, failures, and excessive resource consumption. DeltaFeed solves this problem: instead of a giant file, the partner receives a compact delta feed containing only the changes for the selected time period. This reduces the load on servers and allows for faster catalog updates on websites and in advertising campaigns.

Another advantage of DeltaFeed is configuration flexibility. The client determines the generation schedule themselves: some choose updates every 5 minutes, others once an hour or once a day. Moreover, the system supports a timestamp mechanism, allowing users to explicitly specify the period for which changes are required. This is particularly useful if one of the uploads was missed for any reason. In such cases, data can be requested not just for the last 5 minutes, but for the last 30 minutes or even a full day. Thus, the delta feed guarantees that up-to-date data is always available, minimizing the risk of information loss.

DeltaFeed is actively used by marketers and content departments to maintain data accuracy in advertising campaigns. When advertising platforms like Google Shopping or Yandex.Direct receive outdated stock availability data, it leads to budget loss and the display of ads for items that are out of stock. Thanks to the delta feed, price and stock updates reach advertising accounts within minutes. This increases the effectiveness of advertising campaigns and allows businesses to spend money only on relevant impressions.

A specific application scenario for DeltaFeed is working with marketplaces. Many platforms limit the size of uploaded files or require frequent updates. The delta feed becomes the optimal solution: the partner receives not a full data array, but a lightweight file with the latest changes. This speeds up the moderation and publication process for new products and reduces the risk of errors associated with inconsistent data.

DeltaFeed is equally useful for small online stores and large retailers. Small projects gain the ability to automate catalog updates without involving programmers, while large ones solve the problem of "heavy" feeds and scalability. Furthermore, the delta feed can be used as a standalone tool configured directly in the NotPIM personal account, or as part of the content processing tool ecosystem. When combined with other modules, such as a photo processing tool or a marketplace exporter, DeltaFeed becomes an element of a fully automated data supply chain.

The cost of using DeltaFeed depends on the number of unique products in the catalog. NotPIM uses a simple pricing structure: up to 500 unique products per month can be processed for free. This means that if your catalog contains up to 500 products, you can update their data every day or even every minute, and the system will only count the unique items, not the number of exports. For large catalogs, flexible plans are available based on the matrix size, rather than the number of exports. This approach makes DeltaFeed a cost-effective solution for both small and large businesses.

To summarize: DeltaFeed, delta-feed, or delta feed is a modern tool for automating work with product data. It simplifies synchronization, reduces server load, provides partners only with up-to-date information, and helps marketers manage advertising campaigns with maximum efficiency. Thanks to flexible settings, support for various formats, and integration into the NotPIM ecosystem, the delta feed becomes a universal solution for e-commerce of any scale. If your business deals with a constantly changing catalog, DeltaFeed is the tool that will allow you to save resources and increase data accuracy.
