Announcing v201809 of the AdWords API

Today we’re announcing the release of AdWords API v201809. Here are the highlights:

• More available text in ads. Several ad types now have additional fields, and an increased character count of 90 characters for descriptions. Check out the release notes for more details.
• Traffic split in trials. The new trafficSplitType gives you greater control over how traffic is split in your trials.
• Conversion reporting. The new ConversionAttributionEventType field in the CAMPAIGN_PERFORMANCE_REPORT allows you to segment AllConversions and related metrics by event type (impression or interaction). In addition, the new ConversionAdjustment and ConversionAdjustmentLagBucket fields allow you to determine if conversion adjustments were applied and segment metrics by the number of days between the impression and either conversions or adjustments.

If you’re using v201802 of the AdWords API, please note that it will be sunset on January 30, 2019. We encourage you to skip v201806 and migrate straight to v201809. If you're using v201806, be aware it's now marked deprecated and will be sunset on March 26, 2019.

As with every new version of the AdWords API, please carefully review all changes in the release notes and the v201809 migration guide. The updated client libraries and code examples will be published within the next 48 hours.

If you have any questions or need help with migration, please contact us via the forum.
