Use the Campaign Manager API to upload offline conversions

As a reminder, advertisers must comply with all applicable laws, regulations, and policies related to user consent and data collection. In some cases, IDs might not be available due to application settings.

If you use Campaign Manager 360 for managing and reporting on display campaigns, you can upload conversions from the Campaign Manager 360 API instead of the new Search Ads 360.

Should you use Search Ads 360 or Campaign Manager 360?

We recommend using the Campaign Manager 360 Conversion API because it supports uploading different conversion ID types, uploading to multiple products, and measurement solutions such as Enhanced Conversions..

It's important that you use either Search Ads 360 API or Campaign Manager 360 API, but not both: conversions you upload from both products are not deduplicated and may cause data discrepancies.
