As you probably know, Microsoft and Yahoo have a search and advertising deal in place. Microsoft has now released a guide for migrating from the Yahoo Search Marketing API to its own adCenter API.
The guide is intended to explain how to develop ad campaigns and request reports in adCenter.
"More specifically, the guide maps Search Marketing operations to adCenter operations," explains Microsoft's Scott White. "For those Search Marketing operations that adCenter does not support directly, steps are provided to perform a similar functionality in adCenter, if applicable. The guide includes a mapping from each field in the adCenter objects (for example, Campaign and AdGroup) to the corresponding Search Marketing object and field."
The 46-page guide runs down identifiers, building SOAP requests, quota, deleting entities, fault handling, campaigns (adding, deleting, getting, updating, etc.), ad groups (adding, bidding, deleting, updating, etc.), ads (adding, deleting, updating, etc.), keywords (adding, deleting, updating, etc.), targeting (adding targets, getting targets, deleting targets, updating targets, et.), and reporting (requesting a report, getting the report, report type mapping).
Readers are encouraged to let the company know (presumably via the comments on this announcement) if they come across any missing details that they feel would make the transition process easier.
