Aggregator
To work with aggregators, forming and configuring the upload file for them, go to "Modules -> All modules -> Aggregator".

1. Selecting the desired aggregator for settings and generating the upload file
2. Selecting the list of categories and brands that will be uploaded to the file (the intersection of Category + Brand is triggered)
3. The button for generating the file "not on the fly", without saving the intermediate storage file. Click on the button and copy the link from the browser to the aggregator.
4. If the site has a large number of products and the file generation takes more than 30 seconds, then you can set the file generation to the CRON scheduler, and give the aggregator a ready-made link to the file. When you click on the "Save file" button, there will be a short description with instructions.
There is an option to upload in different languages if the site is multilingual. In the link for generating, you need to add a language identifier (without a language identifier, the Default language works):
sitename/ua/aggregator/service/google/file
sitename/en/aggregator/service/google/file
sitename/ru/aggregator/service/google/file
