Is ther an API that can beused to manage campaigns in adcenter ? I know there is a Keyword analytics interface but what i am looking for is an api to crud campaigns using soap, .net etc ....
Currently the adCenter API is invitation only. You can fill out our interest form to be contacted as we roll out more invitations. You can also contact your adCenter sales representative with questions about the API.
You can learn more about the API at the API Forum and API Blog. This post in particular has more info about access.
