Obtaining Change History of Bid changes, Placements and Keyword

[Vandita Chhabaria]

Hello,

My tool is just a -Reporting only Adwords API Client.

Basically the App downloads a Keyword or Placement report for a particular Date range, fetches data from our local database and computes ROI.

But there is a requirement that, App should be able to display a graph showing

Impact of: MAX CPC 

Impact On: Cost, Conversions, Sales, ROI, CPC, Cost/Conv

Also. the App need to show that 

1. There was a change in MAX CPC on a particular date (As seen in Change History) - Reason for change in ROI

2. There were new placements added(As seen in Change History) - Reason for change in ROI

3. There were new keywords added(As seen in Change History) - Reason for change in ROI

My Question is, I am not able to fetch such changes anywhere. I have used CustomerSyncService, but that just displays the name and ID of campaign and Adgroup where changes were made.

Is there any option that can serve for my requirement ?

Please please help asap !

Hi Vandita,

The only change history-related feature of the API is CustomerSyncService. The idea behind CustomerSyncService is that you would keep a local copy of your account's state (e.g., in a database). You would then use CustomerSyncService to determine which objects (campaigns, ad groups, criteria) have changed, and issue the corresponding API calls to fetch the updated objects, such as an AdGroupCriterionService.get to fetch the criteria in AdGroupChangeData.changedCriteria. You could also use reports for fetching the updated objects in many cases. If you want to determine precisely which attributes of an object changed, you would have to implement that by comparing the object in your local copy to the object returned by the API call.
