Amazon MWS php integration for product Api

Question

I'm trying to develop an application which supports me in my amazon business. For that I wanted to start with a reprice system for my products, which changes automatically the prices on Amazon.
But I have problems with the integration of the Amazon MWS. To get a first result I load the Amazon product library and started with the "GetMyPriceForSKUSample". I put all information in the config.inc which are required. Furthermore, I've checked everything with MWS Scratchpad and it works. In the "GetMyPriceForSKUSample.php" I put these lines:

 $request->setSellerId(MERCHANT_ID);
 $request->setMarketplaceId(MARKETPLACE_ID);
 $request->setSellerSKUList("jb63anzugweiß150cm");

According to the documentation. I only want to see the amount of the article in my screen, but I'm not sure if it's right what I've done. The code in the last few lince are added by myself. See below

I can't help you too much with PHP, but if you use the MWS PHP toolkit, you should just have to plug in your credentials and your SKU/ASIN.

But, if you are looking to reprice, check out the AnyOfferChanged notification. You will get a near real-time price updates from the top 20 offers for your product. You can then update your product's price almost instantly.
