WSI, and full EE support coming soon.
Pulse Storm's new Mercury API extension is the missing link for Magento's XML-RPC, SOAP, and new REST API.
With Mercury API you'll be able to
Improve SOAP performance via WSDL caching
Programmatically create configurable product sets
Programmatically control price modifiers for configurable products
Fetch arbitrary collection data
We want to make Mercury API a clearing house for all the missing API features Magento/eBay can't provide. If you've ever had a pet feature of API gripe let us know, we're collecting the most popular requests and will be rolling out new features over the next coming month. The best part? All updates to the 1.x product version are free for registered users.
Get your copy today and start working with the Magento API instead of against it!
