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 referred to as “delta feed”) is an e-commerce tool that generates product feeds containing only catalog changes. Unlike a classic feed, which always exports the full list of products with all attributes, a delta feed shows only what has changed since the last export: new products, price updates, and stock adjustments. This approach significantly reduces resource consumption, speeds up synchronization, and makes managing large product catalogs much easier.

Technically, DeltaFeed works on a comparison principle. First, the system reads the initial product feed and stores it as a baseline. Then, at predefined intervals — every minute or once a day — the system reads the same feed again and records only the changes. These changes are compiled into a separate delta feed that the client receives in the required format. It can be the original one (CSV, XML, YML) or any other format suitable for CMS platforms, marketplaces, or advertising systems. DeltaFeed eliminates unnecessary data transfer entirely, which is especially important for companies managing catalogs with tens or even hundreds of thousands of SKUs.

Why has the delta feed become such a sought-after tool? Primarily because of system load. Imagine a store where thousands of prices change daily. Exporting a full 200 MB feed every time leads to delays, failures, and excessive resource usage. DeltaFeed solves this: instead of a massive file, a partner receives a compact delta feed containing only the changes for the selected timeframe. This reduces server load and accelerates catalog updates on websites and ad campaigns.

Another advantage of DeltaFeed is flexibility. Clients set their own update schedules: some prefer every 5 minutes, others once an hour or once a day. Moreover, the system supports a timestamp mechanism that lets users specify exactly what period of changes they need. This is especially useful if one of the scheduled updates was missed. In such cases, you can request data not just for the last 5 minutes but for the last 30 minutes or even a full day. This ensures that up-to-date data is always available, with minimal risk of losing information.

DeltaFeed is widely used by marketing and content teams to keep product data in advertising campaigns accurate. When advertising platforms like Google Shopping or Yandex.Direct receive outdated stock or pricing data, businesses lose budget by showing ads for unavailable products. With a delta feed, price and stock updates reach ad platforms within minutes. This increases campaign efficiency and ensures ad spend is used only on relevant products.

Another common use case for DeltaFeed is marketplace integration. Many platforms restrict file size or require frequent updates. A delta feed is the perfect solution: partners receive a lightweight file with only the latest changes, instead of a full dataset. This accelerates moderation and product publishing and reduces errors caused by inconsistent data.

DeltaFeed is equally valuable for small online stores and large retailers. Small businesses gain the ability to automate catalog updates without involving developers, while enterprises solve the problem of “heavy” feeds and scalability. At the same time, DeltaFeed can be used as a standalone tool, configured directly in the NotPIM dashboard, or as part of the broader content automation ecosystem. Combined with other modules, such as image processing or marketplace export, DeltaFeed becomes a key element of a fully automated data supply chain.

Pricing for DeltaFeed depends on the number of unique products in the catalog. On the NotPIM platform, the model is simple: up to 500 unique products per month can be processed for free. This means that if your catalog has up to 500 products, you can update them every day or even every minute, and the system will count only unique items, not the number of exports. For larger catalogs, flexible plans are available based on catalog size rather than the number of exports. This makes DeltaFeed a cost-effective solution for both small and enterprise-level businesses.

In summary: DeltaFeed — delta feed — is a modern tool for automating product data management. It simplifies synchronization, reduces server load, ensures partners always receive current information, and helps marketers run ad campaigns with maximum efficiency. With flexible scheduling, multi-format support, and full integration into the NotPIM ecosystem, the delta feed is a universal solution for e-commerce of any scale. If your business relies on a constantly changing catalog, DeltaFeed is the tool that will save resources and improve the accuracy of your data operations.
