Apple's iAd Workbench API provides Advertisers access the Workbench server to manage their accounts and campaigns. The API includes methods to create campaigns, manage campaigns, and access campaign analytics. A few of the many functions available with iAd Workbench are: update a campaign, receive a list of products or apps you promoted, and summary metrics for any campaign. The iAd Workbench is available to all iAd Workbench accounts and users with Admin access, and uses a Client Side SSL certificate to authenticate users and an Access Token to provide authorization to the API. The API supports JSON-RPC payload over HTTP POST.
