Google has renamed conversions with multiple data sources to multi-source conversions across its documentation and Tag Diagnostics.
Multi-source conversions let advertisers connect an existing website conversion action with an additional backend source, such as a CRM or order database, using Data Manager or the Data Manager API. This can help recover conversions that may be missed because of ad blockers or browser restrictions, while avoiding duplicate counting.
To use the feature, advertisers need a unique transaction ID, the conversion date and time, and at least one attribution identifier such as GCLID, GBRAID, WBRAID, or hashed data.
The feature is currently in beta and does not yet support imported GA4 conversions or URL-based conversion actions.
