Google Ads Conversion Adjustments

Google Tag Manager Server Container

I’m starting to get my hands on Google Ads Conversion Adjustments

I find that everything is clear except for a few information.

How do I retrieve the user data (ENHANCEMENT) so that Google can merge the data?

I should create a variable that gets the value, otherwise I should create tags for each individual request.

I’m not sure I understand your question correctly.
In the incoming request on which you want this tag to work there should be user data, you take this data through variables, add it to the tag and thus when triggered it will be sent to the specified conversion action id.

I’m just starting to get my hands on this configuration and I wanted to understand if just
Google Ads Id, Order Number was enough or if other information was needed too.

I would like to be able to send the payment change from pending to paid from the CRM.
Thanks

Yes, the order number is sufficient for identification, the same one you send when the initial conversion takes place.

Hi stape community,

we are currently testing Google Ads Conversion Adjustments in server GTM and we are running into an issue when trying to retract conversions.

We are using the Google Ads Conversion Adjustments flow and sending a request like this:

{
“conversionAdjustments”: [
{
“conversionAction”: “customers/3600715821/conversionActions/7587047161”,
“adjustmentType”: “RETRACTION”,
“orderId”: 3308369,
“adjustmentDateTime”: “2026-05-11 10:48:09+00:00”
}
],
“partialFailure”: true,
“validateOnly”: false
}

The request returns HTTP 200, but in the response we get:

NO_CONVERSION_ACTION_FOUND
The conversion action specified in the adjustment request cannot be found. Make sure it’s available in this account.

The full error points to:
conversion_adjustments[0].conversion_action
customers/3600715821/conversionActions/7587047161

What is important in our case:

  • we are using the same customer/account context

  • the same conversion action setup works correctly with the Google Data Manager API template

  • conversions are being created correctly there

  • the issue only appears when trying to use Conversion Adjustments / RETRACTION

Could you please help me figure out where the problem might be?

If needed, I can also share more details about the exact Stape template configuration.

Thanks.
