How to publish products?
You can upload product information from file.
Create a CSV-file where each line has one product. Field values shall be separated by semicolon (;). The first line can be a header.
Comma (,) and dot (.) are accepted as decimal separators.
When the file is ready, follow the example (see video below) and upload it the service.
You can upload products also using API. See more information from Products API. With API you can automate, for example, stock balance updates.
