After setting up the profile and fields, open the run step. Eofferix checks products before sending, shows the current task, and keeps the result of the last run.
Start with a test
For the first run, keep Check without sending enabled. Eofferix validates products, required fields, and categories without changing Ozon. When everything is clear, turn this option off for a real send.
Pre-check before sending
The run page should show a green Ozon check block. It tells how many rows were checked and whether the exchange can start. If there are errors, Eofferix shows them and links back to field selection.

Start the exchange
Click Start. The current task block shows progress. After completion, the previous run block shows time, cost, and a link to download the result.
What changes in Ozon
Eofferix sends only what is enabled in the profile: product cards, prices, stock, or publishing actions. Ozon may need time to check product cards, and products without stock may be ready but not available for purchase yet.
