Hello .
We've been working with the IT team to make adjustments regarding S2S you
sent in the last email. it was was helpful, as it says to use the following
for webpage conversions:
For that, we use the call to `uploadConversionAdjustments`, which is of
type WEBPAGE and has enhanced conversions enabled.
However, when we make the call, we get this error.
``` [
{
"partialFailureError": {
"code": 3,
"message": "Can't use enhanced conversions with the specified conversion
action., at conversion_adjustments[0].conversion_action",
"details": [
{
"@type": "
type.googleapis.com/google.ads.googleads.v22.errors.GoogleAdsFailure",
"errors": [
{
"errorCode": {
"conversionAdjustmentUploadError":
"CONVERSION_ACTION_NOT_ELIGIBLE_FOR_ENHANCEMENT"
},
"message": "Can't use enhanced conversions with the specified conversion
action.",
"trigger": {
"stringValue": "customers/1426266091/conversionActions/6479263156"
},
"location": {
"fieldPathElements": [
{
"fieldName": "conversion_adjustments",
"index": 0
},
{
"fieldName": "conversion_action"
}
]
}
]
}
]
"results": [
{}
]
"jobId": "7703933516919568597"
]
The answers I've seen from GPT and Google all say that it needs to have
enhanced settings enabled (which it does) and that it needs to be a webpage
(which it is). But we can't move beyond this step... can you help us with
this new error?
This is the call we made:
https://googleads.googleapis.com/v19/customers/1426266091:uploadConversionAdjustments
Bodysuit:
{ "customer_id": "1426266091", "conversion_adjustments": [ {
"conversion_action": "customers/1426266091/conversionActions/6479263156",
"adjustment_type": "ENHANCEMENT", "order_id": "123123123123123123123}",
"adjustment_date_time": "2025-11-10 12:46:07+01:00", "user_identifiers": [
{ "hashed_email": "example132123" }, { "hashed_phone_number":
"example_123123123" } ] } ], "partial_failure": true }
