Access to the demo environment#

This guide walks you through creating your own app for the Mergado Store, connecting it to the Mergado API, and safely testing it directly in Mergado without having to pay. Mergado allows developers to build custom integrations (“apps”) that extend the editor’s functionality or communicate with its API. There is no official “demo environment” with preloaded data — instead, you’ll set up your own test project in just a few steps.

Calculating and Filtering Percentage Discounts in Mergado

Mon, 01 Jan 0001 00:00:00 +0000

Calculating and Filtering Percentage Discounts in Mergado#

How to Calculate and Filter Percentage Discounts in Mergado?#

This guide walks you through calculating the percentage discount between the original price and the sale price and shows how to filter products by discount level. You need a pair of elements in your feed – for example, in Google format:

original price: g:price
sale price: g:sale_price

From these values, you can easily calculate the discount percentage and use it for feed modifications, exports, or filtering (e.g., show only products with a discount > 10%) and plan campaigns accordingly.

CDATA in Mergado

Mon, 01 Jan 0001 00:00:00 +0000

CDATA in Mergado#

What is CDATA and why does it matter?#

CDATA (short for Character Data) is a way to protect a portion of text in XML from being interpreted as code. In e-commerce feeds, it is mainly useful where elements contain HTML or special characters — typically in <DESCRIPTION> or <LONGDESC>. Without CDATA, HTML tags (e.g. , ) could be read as XML elements, which leads to an invalid feed or lost content.

Everything You Need to Know About Custom Format

Mon, 01 Jan 0001 00:00:00 +0000

Everything You Need to Know About Custom Format#

1. Introduction to Custom Format#

What Is Custom Format#

Custom Format is a feature that lets you teach Mergado to recognize and process virtually any XML or CSV file. It allows you to load any feed into Mergado, define its structure, and then work with the data just like with standard integrated formats.

How and Why to Set Up Price Tiers in Mergado

Mon, 01 Jan 0001 00:00:00 +0000

How and Why to Set Up Price Tiers in Mergado?#

What Are Price Tiers and Why Set Them Up?#

Setting up price tiers means dividing your product range into groups (called queries) based on price ranges (e.g., products priced at 0–199 CZK, 200–499 CZK, 500–999 CZK, 1000+ CZK). In Mergado, this segmentation helps you better target adjustments (such as margin or shipping), choose the right cost per click (CPC) for bidding, and effectively configure PPC campaigns based on price level. Each product segment requires a specific strategy, and knowing which price brackets contain the most products, the highest turnover, or the highest costs gives you a strategic advantage.

Mergado Audit: Guide to technical product feed inspection#

For successful advertising on comparison shopping engines and ad platforms, your product data needs to be accurate, complete, and valid. The technical state of your feed directly affects product approval, pairing, and campaign performance.

Products and Product Queries

Mon, 01 Jan 0001 00:00:00 +0000

Products and Product Queries#

1. Products in Mergado#

What Is a Product in Mergado#

A product in Mergado is the basic data unit representing an item from your online store. Each product contains various elements that describe its properties – such as the name, price, or EAN. Mergado works with these products, modifies them, and optimizes them before exporting to advertising channels.

Products are made up of elements that define their properties (e.g., PRODUCTNAME, PRICE, EAN).
A feed is a file that contains all products and their elements.

Input and Output Data#

The entire process of working with products in Mergado is based on the transformation between two basic data sets – the input and output feed.

Rule: Rewrite

Mon, 01 Jan 0001 00:00:00 +0000

Rule: Rewrite#

The rule is used to modify the values of any element, such as product names, categories, descriptions, and many more. With the Rewrite rule, you can completely replace values, enrich them, or remove parts of them.

Extra features#

Smart paste mode - bulk copy and paste values, for example from Google Sheets
In the New value field, you can enter:
- text
- a variable, for example: %g:brand%
- a combination of text + variable, for example: %g:price% CZK
- an empty value
Option to add multiple rows
Row order matters - rules are applied from top to bottom

Practical examples#

Example 1 – Enriching product names#

Enriching product names with additional information (brand, parameters).

Rules in Mergado Editor

Mon, 01 Jan 0001 00:00:00 +0000

Rules in Mergado Editor#

What are rules?#

Rules are one of the most important tools in Mergado Editor. Using specific rules, queries, and elements, you can modify data according to your needs or the requirements of comparison shopping engines, marketplaces, websites, supplier applications, or other platforms.

Rules are divided into four groups:

Rules created by the Editor (e.g., Conversion Mergado XML [CZ] -> Heureka.cz – product [CZ])
Extension rules (e.g., Bidding Fox - INPUT)
User rules (e.g., Change color parameter)
Manual changes rule

Different types of rules can be modified in different ways. For example, rules created by MERGADO cannot be copied — you can only delete them. On the other hand, user rules can be disabled, duplicated, or deleted.

Streamline Product Data with Mergado Master Feed

Mon, 01 Jan 0001 00:00:00 +0000

Streamline Product Data with Mergado Master Feed#

Do you advertise the same products on multiple advertising platforms and want to avoid making the same edits and setting identical rules for each project over and over? Create one Master Feed and use it as the data source for all your individual projects. It lets you make shared changes in bulk, just once. You will save a lot of time and effort, and then only need to fine-tune each project for the specifics of its target advertising platform.

What IP addresses does Mergado and its extensions use?

Mon, 01 Jan 0001 00:00:00 +0000

What IP addresses does Mergado and its extensions use?#

Why you should know Mergado’s IP addresses#

If your online store or server that provides data feeds is protected and you verify access using an IP address whitelist (i.e. you only allow access from specific addresses), you need to know which IP address Mergado and its extensions use to access your feed. If you don’t allow these IP addresses, Mergado won’t be able to download your feed and the extensions won’t work correctly.

What is the Keychain extension and how to set it up?

Mon, 01 Jan 0001 00:00:00 +0000

What is the Keychain extension and how to set it up?#

Mergado Keychain is an extension that connects your Mergado account with external systems such as Heureka, Zboží.cz, Google Analytics, Shopify, and many others. It works as a secure key — a place where you store your login credentials for these platforms, and Mergado can then automatically pull the necessary data for other extensions like Bidding Fox or Pricing Fox, or for generating statistics and analyses.

What is the Mergado Marketplaces extension?

Mon, 01 Jan 0001 00:00:00 +0000

What is the Mergado Marketplaces extension?#

Mergado Marketplaces is an extension within the Mergado ecosystem that lets you automatically list and manage thousands of products on the Allegro and Kaufland Global Marketplace online marketplaces. The extension pairs products with the marketplace catalog, lists unique ones, and ensures stock levels and prices are always up to date.

Thanks to regular synchronization, it only offers products that are actually in stock, preventing order cancellations and unhappy customers. Users of Shopify, WooCommerce, Shoptet Premium, Upgates, UNAS e-shop platforms and the POHODA accounting system can also conveniently manage orders directly in the admin panel of the system they use. The extension also makes it significantly easier to comply with GPSR regulatory requirements, keeping your offers visible at all times.

Can I secure the output feed in Mergado?

Mon, 01 Jan 0001 00:00:00 +0000

Can I secure the output feed in Mergado?#

Why secure your output feed#

The output feed from Mergado contains all the data you send to advertising platforms (e.g. Heureka, Google, or Facebook) after editing. Although this feed is typically only read by the platform you share it with, it’s understandable that you want to protect your advertising data and keep unauthorized people out.

How Mergado protects output feeds#

Mergado doesn’t support password-protecting output feeds (HTTP authentication), but access to output feeds is naturally restricted thanks to their unique and undiscoverable URLs.

Changing permissions for an online store

Mon, 01 Jan 0001 00:00:00 +0000

Changing permissions for an online store#

Do you have an online store in Mergado but need someone else to make changes in it (e.g. an employee or agency)? Or are you a freelancer or agency managing an online store for a client who also wants access? Maybe they don’t want to edit anything but just wants to occasionally check how the feeds look? Does your manager or business partner want to see what’s happening in the online store while making sure they don’t accidentally change any settings?

Changing the plan for your online store

Mon, 01 Jan 0001 00:00:00 +0000

Changing the plan for your online store#

If you want to change the plan for your online store, you should know that you can’t do it manually. The plan level is automatically determined by Mergado based on the number of products in your output feeds.

In other words, Mergado looks at how many projects (integrations) you have within a given online store and how many products are in the output of each project. It adds up all output products and determines the plan type based on the total count.

Elements in Mergado

Mon, 01 Jan 0001 00:00:00 +0000

Elements in Mergado#

1. What are elements#

Definition#

An element is the basic building block of a feed that carries data. Each element represents a specific piece of information – for example, a product name, price, code, or image. In both XML and CSV, an element serves as a label for where a given value is located.

In simple terms:

element = “name of the information”,
value = “content of that information”.

How to Fix Feed Errors and Prevent Heureka from Rejecting Products

Mon, 01 Jan 0001 00:00:00 +0000

How to Fix Feed Errors and Prevent Heureka from Rejecting Products#

For successful advertising on Heureka, your product XML feed must meet all of Heureka’s requirements. This means it must contain specific elements that are the fundamental building blocks of the data file (XML feed). Mergado takes care of transforming the element structure from your input feed into the structure Heureka requires. However, you are the one who must tell Mergado what information to fill into each element – and you must provide this information in your input feed.

Is using Mergado worth it for me?

Mon, 01 Jan 0001 00:00:00 +0000

Is using Mergado worth it for me?#

The short answer is — yes. If you set up the application properly, you can use it to increase your revenue by tens of percent, easily exceeding the monthly cost of Mergado, which typically runs at a few hundred Czech crowns. On top of that, you will save a lot of time, which, as we all know, is priceless. But let’s break down all the benefits.

JSON in Mergado

Mon, 01 Jan 0001 00:00:00 +0000

JSON in Mergado#

In Mergado, the most commonly used file formats are XML and CSV. However, the Editor also accepts JSON, TSV, and TXT. It may happen that a supplier provides a JSON feed and you need to upload it to Mergado. If the JSON does not load or returns an error when creating a project, the most common cause is an incorrect format or content of the feed.

What is JSON?#

JSON is a lightweight text format for data exchange. It is human-readable and at the same time easily processed by programs — a universal language for passing structured data between systems.

Mergado Keychain Connections Explained

Mon, 01 Jan 0001 00:00:00 +0000

What are the individual connections in Mergado Keychain used for?#

1. Sklik API Fénix#

Create the Sklik API Fénix connection if you use extensions that need access to data from Zboží.cz/Sklik, i.e. data related to advertising on Seznam Nákupy.

Create this connection even if you don’t use any extensions but want to track advertising cost trends or clicks in easy-to-read charts on the Analytics page of your project.

The data collected is used exclusively for analytical and optimization purposes. Mergado does not gain access to personal customer data or individual order details.

What to do when your feed for Audit exceeds 256 MB#

Mergado Audit checks the technical accuracy and data quality of your feed. Currently, it can only process files up to 256 MB.

Complete Guide to Product Pairing on Heureka with Mergado

Mon, 01 Jan 0001 00:00:00 +0000

Complete Guide to Product Pairing on Heureka with Mergado#

Product pairing is one of the most important tasks for successful advertising on the Heureka comparison site. This process links your online store’s offer with a specific product card in Heureka’s catalog. If your products are not paired, they only appear in full-text search, which significantly reduces their visibility and chances of generating orders.

Why Is Proper Pairing Essential for Online stores?#

Joint display with competitors – Paired products are displayed directly on the “main” product card alongside offers from other online stores, so customers see your products in one place compared with the rest. Not as a standalone, isolated offer.
Higher search ranking – Product cards rank higher in search results than standalone unpaired offers.
Bidding capability – Only paired products can fully participate in bidding (setting the cost per click) and compete for top positions among sellers.
Trust and reviews – Paired products let customers use reviews, ratings, and comparisons with other products.
Heureka Marketplace – Correct pairing is one of the conditions for activating the orange “Buy via Heureka” button.

What Are the Key Elements for Successful Pairing?#

For Heureka to correctly identify and classify your product, you need to focus on these three elements:

How to change billing details

Mon, 01 Jan 0001 00:00:00 +0000

How to move a project to a different online store in Mergado?

Mon, 01 Jan 0001 00:00:00 +0000

How to move a project to a different online store in Mergado?#

Do you manage multiple online stores in Mergado and accidentally created a project under the wrong online store? No problem! If you have Owner or Write permissions for both the original and the target online store, you can easily move the project to the correct online store yourself.

ℹ️ When moving projects, keep in mind that according to the Terms of Use, it is not allowed to have multiple different online stores within a single online store. So if you have two online stores, each on its own domain, you also need to create two online stores in Mergado, under which you create the corresponding projects for individual advertising platforms.

Product authorization

Mon, 01 Jan 0001 00:00:00 +0000

Product Authorization#

Product authorization lets you decide which items from the input feed to let into Mergado and which to block. It comes in handy when you have a feed from a supplier and don’t want to offer the entire catalog, or when you want to control every new product that appears in the feed. Below you will find how to enable authorization, work with approval, and how to disable it again if needed.

Rule: Bulk Copy Values

Mon, 01 Jan 0001 00:00:00 +0000

Variables in Mergado

Mon, 01 Jan 0001 00:00:00 +0000

Variables in Mergado#

I. Variables in Mergado Editor#

1. What are variables in Mergado#

Variables in Mergado Editor represent placeholders for specific values from elements. They are “holders” for data that differs from product to product and that you want to further process or use in rules.

A variable can have a different value for each product.
A typical example is the element PRICE_VAT, whose value changes across products.
You can create a variable manually – for example, if you need to extract part of the text from a name or description.
In addition to user variables, there are also special system variables, such as @MERGADO_ID.

Mergado works directly with elements as the source of values. Variables are a supplementary tool for situations where you need to extract only a specific part of a text or further process values.

Assortment Report in Mergado

Mon, 01 Jan 0001 00:00:00 +0000

Assortment Report in Mergado#

Assortment Report from Heureka#

Some Mergado extensions (e.g., Pairing Bear, Bidding Fox, Pricing Fox) work with reports from Heureka – most commonly the assortment report. Heureka generates these reports, Mergado Keychain downloads them, and individual extensions draw data from them for analysis. In this guide, you will learn how the process works, how often reports are generated and downloaded, and what to do when Keychain displays the message “Connection issues” or when data appears in extensions with a delay.

How differential invoicing works in Mergado

Mon, 01 Jan 0001 00:00:00 +0000

How differential invoicing works in Mergado#

Differential invoices are issued due to automatic plan adjustments and price differences that arise when the number of products in your feed changes, when new online stores are created, or when extensions are activated.

Automatic plan changes#

Billing in Mergado is based on automatic plan adjustments according to the number of products in your output feeds. If the product count changes and reaches a different plan tier, the system automatically adjusts the billing. This is how price differences between the old and new plan are reflected on your invoice.

How to disable and enable a project in Mergado?

How to disable and enable a project in Mergado?#

Rule: Add a Value to a Multi-Value Element

Mon, 01 Jan 0001 00:00:00 +0000

Rule: Add a Value to a Multi-Value Element#

The basic principle of this rule is that it adds another value to an existing element you select.

Extra features#

How does the rule behave in different situations? If:

the element has no value yet - a new value is added to the first position, so a multi-value element is not created:

How does data regeneration and updating work in Mergado?

Mon, 01 Jan 0001 00:00:00 +0000

How does data regeneration and updating work in Mergado?#

Why it is important to regenerate data#

When you modify rules, filters, or queries in Mergado, or when the input data from your online store changes, it is important for these changes to actually make it into the output feed that you send to advertising channels. Data regeneration is the mechanism that ensures changes from the data source reach Mergado Editor and that edits in the editor are reflected in the output data flowing to the target platforms. Thanks to this mechanism, you gain control over what actually appears in your advertising.
