Faster product feed synchronisation for Allegro#

Product feed synchronisation for Allegro is now significantly faster. Thanks to a new way of handling synchronisations, feed regeneration runs for multiple users simultaneously, so your product data on Allegro will be up to date much sooner than before.

What’s new:

• Order synchronisation activation is now available directly on the connection overview – no need to navigate to a separate section.
• An optional invoice synchronisation has been added for Upgates. On the online store connection detail, you can now enable sending invoices from Upgates to the marketplace. Actual invoice synchronisation will only work once Upgates approves the new version of our plugin.
• Google Merchant Center: added support for UCP (Universal Commerce Protocol) elements for agentic commerce. In the campaign settings, you can now fill in the Native store, Customer notification type, and Customer message elements.
• Google Merchant Center: added support for nested elements (e.g. Shipping, Certification, Loyalty programmes, Product details, and more). These elements could previously only be partially configured – they are now fully editable as optional elements in the campaign settings.
• For Kaufland orders with delivery to a pickup point, the name of the pickup point and its address are now displayed.
• In the campaign history, product feed synchronisation records now include a “Synchronisation duration” field – you can see exactly how long the regeneration took.

Buddy launches automations on your schedule#

You can now run automations in Buddy automatically – either once at a specified time or repeatedly on selected days and times. No need to think about it or be there. Buddy will run the tasks on its own, exactly when you need them.

What’s new:

• Buddy can now send messages directly to Rocket.Chat channels. Connect Rocket.Chat in Credentials and Buddy will send the message on your behalf – no need to leave the chat.
• Buddy can send a notification to a specific user or to all users with access to the online store directly via Mergado API.
• Quick access – a new section in the menu where you can save your favourite agents, automations, or chats for quick access.
• Various UI/UX improvements.

Opening Mergado to AI agents and modernising Canvas#

We’re launching support for Personal Access Tokens (Personal Access Token - PAT), enabling you to securely connect Mergado with your own scripts, automations, and AI agents (Claude, Cursor, Gumloop, and others). Create a PAT in the API & Access section with an optional validity period (7 / 30 / 90 / 365 days or no expiry) and precise permission settings (scopes) following the principle of least privilege. A token represents a specific user and their granted permissions. It can be revoked at any time.

We’re also preparing a simplified connection of the Mergado MCP server to external services via OAuth. Instead of manually generating a token, you’ll confirm access directly in ChatGPT, Claude, or another supported client in just a few clicks. Fully official apps in marketplaces (ChatGPT Apps, Claude Connectors) will follow later. Preliminary release: May 27, 2026. More in the articles Personal Access Token (PAT) and Connecting Mergado with AI agents (ChatGPT, Claude, Cursor).

We’re also improving the working experience in the Editor, specifically in Canvas, where we are progressively rewriting rule configuration into a new, modern React UI with an intuitive wizard (Stepper). For new users coming from external connectors (e.g. Shopify), we’re introducing an automated onboarding wizard. After registration or login, it guides you through connecting your store without having to manually enter data that the system already knows from the connector.

What’s new:

• Google Merchant Center: feed specifications (XML and TSV) updated with new attributes such as handling_cutoff_time and support for loyalty programmes and video.
• Audit (Google): new validation of variant attributes (colour, size, etc.) for products containing item_group_id.
• Google Fixer: new feature for automatically fixing the missing g:brand attribute based on suggestions from other elements.
• Audit (Google): the g:shipping validator now checks the presence and completeness of the required sub-elements g:country and g:price.
• Rules: the “Merge Variants” rule is now available for custom (Custom) variant formats as well.
• Automations: new “Activate extension” action that automatically activates the required extensions when an automation runs.
• Shoptet Complete: format updated with new elements PURCHASE_VAT, PURCHASE_PRICE_INCL_VAT, and BOX_RESTRICTION.
• Keychain: when selecting a profile in Google Merchant Center, the account ID is now displayed to better distinguish multiple accounts with the same name.
• Keychain: terminology unified from “app” to “extension” in the Sklik, Heureka, and GA4 connections.
• Keychain: when a Sklik connection test fails, a clear error message is now shown (e.g. invalid token or venue ID).
• Data file import: specific HTTP error codes and clear descriptions of failure reasons are now shown in the project history (e.g. timeout or missing permissions).
• Feed analysis: new support for displaying the element tree structure for XML and JSON feeds.
• Fixed: incorrect overwriting of availability based on the availability date in all Google format conversions.
• Fixed: filters for displayed items and translations corrected in product authorisation.
• Fixed: incorrect Keychain connection creation within the wizard, which resulted in a blank page, has been resolved.
• Fixed: main product categories are now correctly transferred in direct conversions from UpGates to Shoptet.
• Fixed: misleading “Polish” label removed from Allegro references in the Mergado Editor wizard.
• Resolved: when a CSV feed contains an invalid row, the system now generates a warning and skips it instead of terminating the entire process with an error.
• Resolved: in the UNAS connection, a non-functional state of the online store is now detected with clear guidance for the user to resolve it in the UNAS administration.
• Fixed: tooltip display for projects disabled due to billing.

Buddy now works with data from Plausible Analytics#

Buddy can now answer questions about your website traffic statistics. Connect it to Plausible Analytics and ask directly in Buddy – how many people visited your site, which pages are the most visited, or how many visitors came in a given period. No need to switch between tools – your data is right where you’re already working.

What’s new:

• New AI models added: Claude Sonnet 4.6, GPT-5.4, GPT-5.5, and Gemini 3.1 Pro.
• Interactive tutorials have been added to the Chat, Automations, and Agents pages to help you get up to speed with the extension faster and more easily.
• Chat settings have been redesigned for better clarity. The sidebar on the Agents and Automations pages can now be hidden.
• Fixed: Editing automations now works correctly.

Updated e-commerce platform requirements for product images#

Your product images will meet the requirements wherever you advertise – on Heureka, Zboží.cz, Google Shopping, or social media. The changes primarily concern image dimensions and are reflected not only in the preset output sizes in Feed Image Editor, but also in your project diagnostics and Image Audit.

What’s new:

• Improved workflow for alternative images (template priority settings, undo/redo, template import and export, working with template actions).
• Simpler and more intuitive work with grouped layers.
• Ability to resize elements on the canvas using the mouse scroll wheel.
• Smoother experience with filters and retention of the last set values after turning them off.
• Automatic product loading when creating the first template in a new project.
• More accurate template previews showing only the products the template is applied to.
• Unsaved changes warning now also applies to alternative templates.
• Easier switching between preset and custom output formats.
• Cleaner workspace by hiding information about effects used in the template.
• Zooming in and out with the magnifier now only affects the canvas, not individual layers.
• Improved animated GIF timing settings, so you can fine-tune both the speed and smoothness of animations for ads on Google, Facebook, and Instagram.

Notification of failed product card listing in automatic listing#

If some product cards fail to be listed during automatic listing, Mergado Marketplaces will now automatically notify you – via Mergado messages or by email, depending on your settings. This way you won’t lose sales due to an error you might otherwise miss. The new notification “Failed creation of product cards in automatic listing” can be found in the “Notifications” section under “Error alerts”. The notification includes a direct link to the unsuccessfully listed cards so you can fix and relist them as quickly as possible.

What’s new:

• Added the option to pause sales for Google Merchant Center – you can pause individual offers or the entire campaign in settings. When sales are paused, the destination_excluded attribute will be assigned to all products in GMC, preventing your products from being displayed anywhere.
• Offers with the status “Active with error” can now be paused and restarted after resolving the issue.
• A search function has been added to the optional elements section of Google Merchant Center.
• Fixed: The orange warning for an empty element now correctly disappears after deleting that element.
• Fixed: Tooltip line break for optional elements in the campaign creation wizard.
• Improved: Error messages for orders now use the same localisation system as offer errors, ensuring consistent and translated messages.

Buddy launches automations and introduces the Gemma model#

Buddy can now do more than just answer questions. You can now set up automations. Buddy will run agents and predefined workflows on its own, without you having to enter instructions manually each time. Every manual input consumes tokens, while automations handle routine parts of recurring tasks using an automatically generated program, not AI. This saves a large number of tokens and results are more consistent. AI only processes the final output. We are actively testing this feature and continuously improving it.

What’s new:

• New model: Gemma – We’ve added the Gemma model, which runs directly on Mergado’s servers. Your data never leaves our server room. It’s suited for faster and simpler tasks where you don’t need the most powerful model.
• Tool: Pricing Fox – Buddy can now work with data from Pricing Fox. Ask it about the number of orders in a given period or current revenue.
• Tool: Mergado Help – Mergado’s documentation is now available directly in Buddy. This allows it to better answer your questions about how Mergado works.
• Fixed: Buddy did not accept the user’s reply in some conversations, causing the conversation to appear “stuck”. It now responds correctly.
• Fixed: Buddy can now answer queries like “list projects with a specific app enabled (e.g. Pricing Fox)”. It correctly goes through the projects and lists the results.

Support for PHP 8+ in PrestaShop 9#

Mergado Pack is now fully compatible with PHP 8+ in PrestaShop 9. You can use the latest version of the environment without worrying about the module’s functionality.

What’s new:

• Fixed: the PrestaShop plugin no longer displays an HTTP 500 Internal Server Error on newer versions of PHP.

New data source connections and a cleaner dashboard#

The new version simplifies connecting data sources and brings a more streamlined dashboard on the home page.

What’s new:

• All input connections are now set up in one place – in Mergado Keychain.
• New cost and margin statistics on the homepage give you a faster overview of key data right after logging in.
• Saving costs from GA4 expands the options for evaluating campaign performance and working with analytics data.
• New diagnostics show new and dropped products, making it easier to track changes in your product catalogue.
• Smarter element sending when applying rules speeds up feed regeneration in Mergado.
• This version focuses primarily on new features, overviews, and integrations.
• The release also includes ongoing technical improvements tied to deployed changes.

API connection to Google Merchant Center (beta)#

You can now connect Mergado Marketplaces directly to Google Merchant Center via API (unverified connection). Products are uploaded and updated faster, more frequently, and with a lower risk of errors. Learn more about the new connection in our article. The beta version currently handles product import and updates – more features will be added over time.

Editing alternative product images#

You can now edit alternative product images, not just the main one. This lets you make full use of all your product images. We added this feature mainly for Meta Carousels, where demand was highest. Editing alternative images is also useful for Amazon, Google, and Allegro. Templates are applied in bulk and automatically – just as you’re used to with Feed Image Editor.

What’s new:

• Alternative images can be edited in the same way as the main image.
• You can apply a template to all alternative images or only to the ones you select.
• Fixed text alignment when using letter spacing.
• The collage preview now correctly displays layer order.

Google Shopping in new countries#

Google has opened Google Shopping in new countries and Mergado is ready. The newly added countries are: Bulgaria, Croatia, Estonia, Latvia, Lithuania, Luxembourg, Slovenia, Cyprus, Malta, Bosnia and Herzegovina, Serbia, Liechtenstein, Moldova, Montenegro, and North Macedonia.

What’s new:

• Mergado now supports the Prisjakt format (SE, NO, DK, FI, FR, IE, NZ, GB) including a converter. In the project settings for Prisjakt output format, you can fill in the “Shop URL”, which is written to channel | link. The project name is written to channel | title.
• Feed audit: added a new fix for automatically hiding products without g:image_link.
• Project analytics now includes data from the new SKlik API Fénix.
• Improved zoom and scroll behaviour in the canvas.
