Max Products Per Run determines the number of products per run. Default: 50.

Start Product Download.
Check the Product Download Log.
Start the next batch or let the job run.
On errors, note the last Magento ID/SKU.

Use smaller batches for many attributes/images or tight API limits; increase only after measuring run time and stability.
