A new visitor signed up my site yesterday. (S)he added an eBay account and item importing process started automatically. But the user has more than 10,000 items. My software calls GetItem api call for each items, so it was over the daily usage limit(5000). I have to monitor the api call count.

I already implemented to keep simultaneously request to eBay API gateway server under 18 threads. But I don’t implement total call limit yet.

I know that I should pass the eBay application compatibility check but there are many things I have to do.
