Hi,

I'm experiencing an issue with duplicate conversions when using the CM360 API. I am uploading conversions (which are transactions) with a Click ID.

I am including an ordinal value which is the transaction ID concatenated with the Click ID (e.g. 'ORDER1|Cvwknheihd_11nudugdy3873ji) which is unique for each combination of transaction and click.

However once the conversions reach SA360, the conversion values are being duplicated. The documentation does not point to any solution to the problem so I'm wondering if there is any reason why the platform would be doing this?

Example of Conversion Being Uploaded:

FLOODLIGHT_CONFIGURATION_ID: 10333593
FLOODLIGHT_ACTIVITY_ID: 11928900
ORDINAL: P1002367571|CjwKCAjwo8-SBhAlEiwAopc9W2HEFi9eVQxZT3A9TNBzIW_AkKtygxMU6mON4OlV_qa6PzirC6d1-xoCi0IQAvD_BwE
GCLID: CjwKCAjwo8-SBhAlEiwAopc9W2HEFi9eVQxZT3A9TNBzIW_AkKtygxMU6mON4OlV_qa6PzirC6d1-xoCi0IQAvD_BwE
VALUE: 9.23
QUANTITY: 1
TIMESTAMP_MICROS: 1649718424000000

When the Data Reaches SA360 (Observed When Downloading the Conversions Report from the UI)

Single uploaded conversion becomes 2 conversions in SA360
Value and GCLID combination appears twice against different "Advertiser Conversion ID" and "Conversion ID" values

Any help would be greatly appreciated!

Thanks

Hello Sean,

Michael here from DCM API Team.

Ordinal values control how duplicate conversions are processed. If multiple conversions are inserted with the same Floodlight values, user identifier, and conversion date, the ordinal is used to determine whether:

The conversions are deduplicated and only one survives. This happens if all conversions have the same ordinal value.
The conversions are processed individually and all survive. This happens if all conversions have a different ordinal value.

The values themselves don't need to be meaningful. In general, using a fixed value (such as 1) for all conversions will enable deduplication. Using a random or unique value for each conversion will disable it.
