Send online conversions

Workflow overview

To send event data with the Data Manager API, complete the following steps:

  1. Prepare destinations: Define the Destination objects for the destinations field of the ingestion request to specify the target account and conversion or event destination. See Prepare destinations for details.

  2. Prepare event data and identifiers: Construct each Event and include any required fields and identifiers. Normalize and SHA-256 hash any user contact information in userData according to the formatting guidelines, and optionally encrypt it. See Prepare event data for details.

  3. Build and send the ingestion request: Submit an events.ingest request containing your destinations, Event records, and encryptionInfo if you encrypted userData. Use validateOnly: true to test your payload for fast-fail errors before sending production data. See Send events for field requirements and code samples.

  4. Check request status and diagnostics: Check asynchronous processing status and review diagnostics with requestStatus.retrieve.

Conversion adjustments

To adjust a previously recorded conversion, send an event with the same transactionId as the original event. For details, see Conversion adjustments.

  • Adjust real-time conversion values: Send accurate financial updates (like restatements, upsells, or finalized cart totals) from your CRM to override the initial estimated value.
  • Enhance measurement accuracy: Supplement your conversions with missing user-provided data (like email or phone number) to mitigate signal loss, recover conversions that may be missed by the Google tag, and unlock better bidding.
