According to this announcement, the Amazon Product Advertising API will change October 25 2011, to require sending an Associate Tag with every request.
In the past, they’ve sent out mass email sometimes when this API changes to all registered users, but this time I only found out about it because, my application just started erroring. Like just now, within the past couple hours, I think. Even though it’s only October 18, not October 25.
So be warned!
Okay then, guess I better get an Affiliate ID. This is a bit annoying, because I certainly don’t want to receive any money from an Affiliate ID — this use is at work at an academic library, I couldn’t take any money myself, and it’s really not worth the beaurocracy to figure out how to have this money go to library, when it probably won’t be very much money, and we don’t really want a profit motive to send things to Amazon. We just want to use the Amazon API to get details on books and Amazon availability.
But okay then!
I don’t think any of the other API changes will effect me, although I’m a bit worried about “Selected ItemAttributes that are not relevant to the broader product advertising use case will be deprecated”, not sure if that even applies to my use case, but if it does, and means that some data that I use will be going away (cover image? Citation metadata?), that would be inconvenient.
