Starting October 1, 2019, accelerated budget delivery will no longer be available for use with search campaigns, shopping campaigns, or shared budgets. This will affect budgets in all versions of the AdWords API, Google Ads API, and Google Ads scripts.

Google Ads will stop respecting the ACCELERATED delivery method setting on any budgets of the above types. Campaigns using such budgets will be automatically switched over to use standard delivery instead.

Note: When a new budget is created using the API or scripts, it is shared by default. Thus, a newly created budget will behave as STANDARD. To explicitly create a budget with ACCELERATED delivery, all of the following conditions will need to be met:

• The budget’s isExplicitlyShared field is set to false
• The budget’s delivery method is set to ACCELERATED
• It is not associated with a search or shopping campaign

Fields and methods affected

Google Ads API	campaign_budget.delivery_method
AdWords API	Budget.BudgetDeliveryMethod
Google Ads scripts	Budget.setDeliveryMethod() Budget.getDeliveryMethod()

API applications and scripts that set the ACCELERATED delivery method will continue to function and will not return any errors when attempting to set the ACCELERATED fields on budgets. However, the setting will not have any effect for shared budgets, or for any budget attached to a search or shopping campaign; the setting will be defaulted to STANDARD delivery instead. Get or mutate responses from the AdWords API on any affected budgets will show the budgets as STANDARD.

The ACCELERATED delivery method may eventually be removed from future versions of the APIs and scripts for the affected budget and campaign types. We will provide additional details regarding any further changes in a later post.

If you have any questions about this change, please don’t hesitate to contact us via the AdWords API and Google Ads API Forum or the Google Ads scripts forum.
