Yes, the module needs to be configured to work properly. Setup for exports is done in 3 easy steps:

  1. on the first tab of the module Settings” choose in which language version and currency you want to generate the XML feed (or multiple feeds). Typical example: czech + CZK”, slovak + EUR”, etc. (Valid for PrestaShop and OpenCart).
  2. On the Cron Tasks” tab, links for generating XML feeds will be available. For one-time generation, just click on these links and the feed will be generated (or re-generated if it already exists). To automate the generation at regular intervals, copy the links and set them up on your web host in cron-running tasks (more on cron setup in the next Q&A).
  3. On the XML feeds” tab, you can download the XML feed or use the link to create a new export to Mergado. 

To set up Ad Systems, you need to fill in the appropriate API keys or IDs and activate the features. 

The module allows you to export data from your online store in XML format, in Mergado XML specification. Such data can be used to connect your store to Mergado, where you are able to convert your product data to hundreds of different formats for comparison shopping services such as Google Shopping, GLAMI, etc., or for advertising systems like Google Ads, Facebook, or for different eCommerce solutions, e. g. Shoptet, etc. 

In addition, the Mergado Pack plugin is equipped with many marketing features to help you improve your advertising. Integrated support for Google Analytics, Facebook Pixel, GLAMI piXel, Heureka and much more.

WooCommerce

Cron is a scheduled task on your server, so it is usually set up on the web hosting of your ecommerce store. 

WP Cron are actions that are executed when loading WordPress sites. Every time the website loads, the tasks for WP Cron are checked. It doesn’t matter if you are in administration or on the frontend. Each time a visitor loads a page, WordPress checks to see if any action should have been taken.
However, it is generally not recommended to use WP Cron, which can affect the speed of WordPress Sites, especially for low-traffic sites.

The Mergado Pack plugin for WooCommerce contains an automatic check for a new version, in which case it will display a notification in the administration (in the Menu Plugins). After installing the plugin, you will always find out if a newer version with new features is available.

You can add the plugin to your e‑shop in the standard way from the plugin directory in the administration of your WordPress site or from the WordPress.org repository. Just look for the Mergado Pack. Above you will also find a link to download the module manually.

In the store administration, go to the Plugins -> Add new tab and search for Mergado

 

After successfully uploading the plugin, click on the Activate plugin button.

Export XML feeds

Cron is simply an automatic task launcher, so it can, for example, start generating an product XML feed from your e‑shop at regular times. Cron can be set up at your web hosting. About cron settings, it is necessary to log in to the administration of your web hosting and find the cron settings there, or contact your web host for more information. 

More about cron in our article

  1. First try setting up batch generation. On the Settings page, in the Batch Export Generation section, enter 1500 and save. Then try generating the feed again. On the Cron page, start the generation with the Manually generate feed button. Then go to the XML feeds page and rerun the feed generation with the Manually generate feed button until the XML feed link is active.
     
  2.  

  3. If you still encounter an error during the generation process after setting up the batch export, please contact us using the contact form on the Support page or email prestashop@mergado.com. Please attach as much information as possible to your email. Your CMS version, PHP version, Mergado Pack module version and other information that will help us determine the cause of the error.

  1. First, go to the Settings tab. If you have a large number of products or problems with feed generation in general, choose a limit in Settings and the product exports will be generated in batches.

  2. For WooCommerce only - If you use multiple tax rates at the same time (e.g. for different countries) select which rate will be used in the XML feed.

  3. In the second menu item, you set up Cron tasks. Here you will find a list of Cron URLs that you can copy and paste into the task scheduler. 
    More about cron jobs in our article

    To generate a feed for the first time, you must first click the Manually generate a feed” button (PrestaShop). 
     

    For WooCommerce only - You can also use the internal WP cron and set up feed re-generation directly in the Mergado Pack administration.

     

  4. Then in the XML feeds tab you will find a list of feeds generated at least once. On this page you can further work with the feeds, delete them, copy them and use them in Mergado Editor, download them or check the progress of the generation.

Gradual regeneration of exports brings important improvements in their creation. With a large amount of data, problems arose and in some cases the whole process ended in failure. Our Mergado Pack therefore offers the option of choosing the number of products that will be generated in one step. And thanks to the limit, only the number of items that the user chooses is subsequently created. This speeds up the process, stabilizes it and reduces the risk of it falling

In practice, this means that the feed is generated in partial files, which are merged after this process and create a complete XML feed.

Heureka

You can generate the availability feed in the WooCommerce and PrestaShop modules. 

  1. In the module, go to Ad Systems -> Heureka. In the Heureka : Other settings section, activate the Availability feed

     

  2. Then on the XML feeds page, generate the Availability feed. Follow the same procedure as for generating a Product feed. 

Biano

The Biano Button cannot be directly activated in the Mergado Pack plugin. 

But we have prepared a tutorial How to set up the Button using Mergado Pack and Google Tag Manager. 

You can generate a Merchant ID in the Biano administration on the Settings > Biano Pixel page.

GLAMI piXel and TOP

To protect emails sent from your domain, add the following entry to your SPF record: _emailing.glami.cz

Example: if your domain has an SPF record of the form v=spf1 ip4:1.2.3.4 ‑all, then the modified version will be v=spf1 ip4:1.2.3.4 include:_emailing.glami.cz ‑all

All outgoing emails from GLAMI are signed with the DKIM key. Create a subdomain glami-review._domainkey to your domain with a DNS CNAME record pointing to partner-review._domainkey.glami.cz

Some hosting providers require a period at the end of the record. Example: glami-review._domainkey.glami.cz.

You can verify the correct email settings in the partner administration in the GLAMI TOP -> Settings tab, where you will see the SPF and DKIM status, marked as Verified” in case of correct settings and Unverified” in case of error.

If you are not sure how to complete these steps, contact your webmaster.

 

 

 

In order to successfully set up the email sending system, you need to complete two steps:

  1. In the GLAMI partner administration, under GLAMI TOP -> Settings, set up an email from which GLAMI will send customer emails with the questionnaire. This email should have the same domain as your e‑shop. For example, www.shop.cz will have the email reviews@shop.cz.
  2. Change the DNS settings for your site’s domain (this is the same domain you used to send the emails from step 1) as instructed below. This setting is important so that emails end up in your customers inbox and not in their SPAM folder.

Árukereső

Árukereső sends emails on behalf of your email address used during registration. To send emails correctly, it is advisable to set up Sender Policy Framework (SPF) on your domain. Some email servers may verify the origin of the sender and your review requests could end up in SPAM.

Árukereső recommends adding an SPF record to your domain’s DNS TXT for their server _spf‑c.arukereso.hu’.

If for some reason you are unable to edit the DNS SPF records, Árukereső recommends that you notify info@arukereso.hu. Emails with questionnaires will be sent from megbizhatobolt@arukereso.hu.

In the administration Árukereső in the tab Beállítások -> Véleménybekérő levelek kiküldési idejének módosítása you can change the number of days from the order until the email is sent to the customer.
