Entity Differences between adCenter API Version 5 and Version 4


Archived: January 10, 2008


adCenter API Version 5 and Version 4 contain significant differences between the campaign management entities.

For example, adCenter API Version 5 contains the AdGroup and Keyword classes, while the corresponding classes in adCenter API Version 4 are AdCenterOrder and AdCenterOrderItem.

Learn more about the campaign management entities and differences between Version 5 and Version 4 at Microsoft adCenter Entities.

The differences between Version 5 and Version 4 are not merely class name changes; plan your migration as a major application rewrite.

Also, consult the Microsoft adCenter API Version 5 Release Notes as you prepare to migrate your applications to Version 5.

Thank you.
