iDEAL Easy (ABN AMRO) payment gateway

[xen]

My iDEAL Easy account with ABN AMRO has been activated today, however I am not sure how to proceed. The only value I am able to fill in without hesitation is the "Merchant ID".

Also I noticed "Postbank/ING" is mentioned everywhere. Is this supposed to be some sort of advertisement for ING or does this payment gateway only work with ING? If the latter I am not sure what to say. Why on earth would anyone want to support a crappy bank like that? Not to mention all serious businesses are with ABN AMRO and otherwise with Rabobank.

Could someone please instruct me how to correctly set this up? As any Dutch person would know, having iDEAL is a must.

Thank you.

Decided to go with iDEAL from Mollie, since iDEAL Easy does not seem to support payment status check and it is hard to implement.
