UploadClickConversions deprecated from 15 June: migration window narrowing
Arpan Banerjee has flagged a second hard deadline from Google: UploadClickConversions is deprecated, effective 15 June 2026. After that date, the API method for uploading click-attributed conversions will no longer be supported, and integrations still using the deprecated endpoint will break.
What changed
Google has detailed the migration path in the Google Ads Developer Blog ("Changes to offline click conversion"): advertisers should migrate to the new UploadConversionAdjustments flow or equivalent supported endpoint before 15 June.
The deprecation matters most for advertisers running offline conversion imports through the Google Ads API: typically B2B lead-gen accounts, CRM-driven Smart Bidding setups, or any account where post-lead outcomes (qualifications, closed-won, revenue) feed back into bidding through an automated pipeline. A broken offline conversion import after 15 June would degrade Smart Bidding signal quality across affected campaigns silently.
Why it matters for advertisers
For you, this means engineering teams responsible for offline conversion integrations should audit which Google Ads API endpoints are in production use, then plan migration before 15 June. Particularly urgent for high-spend lead-gen accounts where Smart Bidding performance depends on a continuous offline conversion feed.
