We have added support for AdWords API v201802 reports in AdWords scripts. The key changes in this release include:
  • A new report type, LANDING_PAGE_REPORT, to provide performance stats for the pages that receive traffic from your ads.
  • ConversionLagBucket field added to various reports to help you determine how long it takes customers to convert.
  • New fields added to support Gmail ads.
Read the AdWords API release notes for complete details, including additional features not listed here.

If you use API versioning in your reports, you need to modify your code to use v201802: 
var report = AdWordsApp.report(query, {
  apiVersion: 'v201802'
});
If you don't use API versioning, no code changes are required. We are updating the default reporting version to v201710 along with this change, and your reports will upgrade automatically.

If you have any questions about these changes or AdWords scripts in general, you can post them on our developer forum.
