For Australian SMBs, the first move is to audit the workflow that creates campaigns, then test alternatives before changing live budgets. ## What Changed on 3 August 2026? From 3 August 2026, new Smart Campaigns cannot be created through the Google Ads API. Existing Smart Campaigns can still be updated and continue to serve ads. Google recommends evaluating Performance Max, Search and Demand Gen depending on the business goal. These are options to assess, not an automatic migration button or a promise that settings, reporting or results will carry across unchanged. > A creation restriction is a workflow signal, not a reason to rewrite every live campaign. > > — RxAI operating principle ## Which Workflow Step Is at Risk? The highest-risk step is the entrance that creates a new campaign. It might be a Google Ads management tool, an agency platform, a CRM integration, a spreadsheet-driven script, a seasonal campaign copier or an internal scheduler. This business impact is a practical inference from the API change, not a Google incident statistic. If a new-customer setup or seasonal promotion depends on an automated create request, the first visible symptom may be an unsuccessful launch rather than an existing campaign disappearing. ## How Can You Find Smart Campaign Creation Requests? Google’s developer guidance gives engineers a precise starting point. Look for campaign mutate requests with create operations where: - advertising_channel_type is set to SMART - advertising_channel_sub_type is set to SMART_CAMPAIGN Then: 1. Search application code, integration settings, vendor documentation and request logs for those fields. 2. Record the API version and the system that sends the request. 3. Confirm which team or vendor owns the failure notification. Google says a v24 create request can return SmartCampaignError.CREATION_FAILED, while v23 and earlier can return OperationAccessDeniedError.CREATE_OPERATION_NOT_PERMITTED. ## What Should You Test Before Moving Budgets? Use a low-risk account, draft environment or narrowly scoped campaign. Keep these checks separate: - **Creation:** Can the replacement create the right objective, audience, location, assets and conversion settings? - **Updates:** Can the team change budget, creative or targeting without losing the review trail? - **Control:** Can an authorised person pause, enable or roll back the campaign? - **Reporting:** Do dashboards, alerts and exports still answer the questions used for decisions? Performance Max, Search and Demand Gen have different objectives, inputs and reporting behaviour. Compare the workflow and decision points before comparing performance claims. ## What Can You Audit in 10 Minutes? Add four columns to your advertising automation register: 1. Who creates the campaign? 2. Which tool sends the request? 3. Which campaign type is created? 4. Who is notified when creation fails? If one answer is unknown, mark the step for human review. Then ask an engineer or vendor to confirm the two Smart Campaign fields, the API version and the replacement test plan.

This is practical workflow guidance, not an advertising performance guarantee or Google migration certification. ## Sources - [S1 — Google Ads Developer Blog: Changes to Support for Smart Campaigns in the Google Ads API](https://ads-developers.googleblog.com/2026/06/changes-to-support-for-smart-campaigns.html) - [S2 — Google Ads API: Feature deprecations and unversioned changes](https://developers.google.com/google-ads/api/docs/deprecations) - [S3 — Google Ads API: Smart Campaigns overview](https://developers.google.com/google-ads/api/docs/smart-campaigns/overview) - [S4 — Search Engine Land: Google Ads API to stop supporting new Smart Campaign creation](https://searchengineland.com/google-ads-api-to-stop-supporting-new-smart-campaign-creation-480999) Sources were checked on 5 August 2026.

From 3 August 2026, new Smart Campaigns cannot be created through the Google Ads API. Google says existing Smart Campaigns can still be updated and will continue to serve ads. ### Can existing Smart Campaigns keep running? Yes. Google’s deprecation guidance says existing Smart Campaigns can be updated and will continue to serve ads. Check separately whether another system depends on creating new campaigns. ### How can I identify an affected workflow? Ask an engineer or vendor to search campaign create or mutate requests for advertising_channel_type set to SMART and advertising_channel_sub_type set to SMART_CAMPAIGN, then confirm the API version and ownership. ### Should an SMB switch every campaign to Performance Max? No. Google recommends evaluating Performance Max, Search and Demand Gen depending on business goals, but the right replacement needs a scoped test of creation, updates, controls and reporting.
