How to create a cron task for Amazon module

[planetajuguetes]

Hi, 

I use Amazon module to update my stock and I update my stock through webservice (my POS makes changes directly to the sql). Module uses synchronization by hooks and my POS does not trigger the necessary Hook to its proper functioning.

I can do it manually going into a tab and selecting the whole catalog. I have to tick the option and then click submit.

Does somebody know how I can make a cron job to do this task automatically?

Have you talked to the module developers - they are very good

I have. They asked me for nearly 200€ before they would answer any question.
