I’ve been playing around with a nifty skunkworks project using our SOAP API, the ext/soap extension in PHP 5, and the fad du jour of AJAX.
Progress has been moving a long at a nice clip, as long as I can find time to work on it. One of my main goals is to more extensively test the compatibility between ext/soap and eBay’s SOAP interface. With the release of PHP 5.0.4, you can finally make SOAP API calls to our servers. I’d done enough to confirm this, but I’d done minimal testing to verify if this applies to all 100+ API calls. Now I’m trying to throw some real-world tests at the extension.
The bad news is that I’ve found a bug. The good news (for PHP) is that the bug is on eBay’s end. :)
The eBay SOAP API is almost 18 months old, but historically many of our developers have used our legacy XML API, which is based on a different codebase. That older codebase has extensive burn in and testing. The newer SOAP codebase is still well-tested (we have over 10 dedicated API QA engineers in addition to the many millions of API calls made by developers), but there are some dark little corners that are not as well-lit.
It turns out I stumbled down one early this morning involving our Motors site. Apparently, according to our SOAP API, the car I’m searching for has 154242 miles and, by an odd twist of fate, was also released in the year 154242. Heh.
We’re in the process of a giant migration, where all the legacy XML API developers move over to share the new SOAP API codebase. (You don’t need to move over to SOAP as part of this transition, but the data schema is changing to one that’s more well-thought out and coherant.) I suspect as we close in on the cutoff date of next June, we’ll run into a few more of these buglets. This is why we’re encouraging people to start porting sooner rather than later.
Unfortunately, when you expose so much data in so many different ways off of a dynamic database driven site, you’re never going to be able to find everything ahead of time. Fortunately, with more eyeballs, all bugs are shallow, and I know our API team will roll out the fixes in no time.
Much magic indeed.
