Enhanced conversions for web enables you to improve the accuracy of your web conversion measurement by uploading conversion adjustments that contain transaction IDs and hashed user identifiers.
Make sure to review the Getting Started guide and implement the prerequisites for enhanced conversions for web before proceeding with implementation.
Usage flow
Here is the overall flow for uploading enhanced conversions for web in the Google Ads API.
Make sure you've implemented the prerequisites, which include the following:
Enable conversion tracking.
Accept the customer data terms.
Configure tagging on your website.
See Implement the prerequisites for detailed guidance.
Normalize and hash the user data, such as email address, phone number, and mailing address.
Put the normalized and hashed user data into
ConversionAdjustment
objects. For eachConversionAdjustment
, do the following:Set
order_id
to the order ID of the conversion to be adjusted, which should match the order ID that was sent by the tag.Populate
user_identifiers
with the normalized and hashed user data. If you have multiple user identifiers available, create a separateUserIdentifier
for each one, up to five identifiers.Set
adjustment_type
toENHANCEMENT
.Set
conversion_action
to the resource name of aConversionAction
with atype
ofWEBPAGE
. This should be the resource name of theConversionAction
you created when you implemented the prerequisites.(Optional) Populate
gclid_date_time_pair
for the most accurate measurement. Setconversion_date_time
to the date and time at which the conversion with the specifiedorder_id
occurred. Include the timezone offset and use the formatyyyy-mm-dd HH:mm:ss+|-HH:mm
, for example:2022-01-01 19:32:45-05:00
(ignoring daylight saving time) .(Optional) Set
user_agent
to the user agent of the request that sent the original conversion so the conversion and its enhancement are either both attributed as same-device or both attributed as cross-device.
Upload the
ConversionAdjustment
creation operations to theConversionAdjustmentUploadService
, settingpartial_failure
totrue
.Review your uploads.
Best practices
Keep the following best practices in mind when implementing enhanced conversions for web.
Include multiple identifiers if you have them
If you have the gclid for a conversion, we recommend sending it in addition to
the user_identifiers
for improved performance. Further, if you have more than
one UserIdentifier
for the conversion, including multiple can improve the
likelihood of a match. Include all identifiers on the same
ConversionAdjustment
.
Review partial failure errors when setting up your integration
When you're first setting up your enhanced conversions for web integration,
review and address any partial errors in the
partial_failure_error
field of the response. If there are issues in your setup, you can inspect this
field to investigate and address them. For more details and examples around
partial failure error handling, visit the dedicated partial failure
guide.
Once you've resolved any issues that surfaced in partial failure errors and your integration is complete, switch to using offline data diagnostics to regularly review the health of your conversions.
Batch multiple adjustments in a single request
If you have multiple adjustments to upload, batch the operations into one
UploadConversionAdjustmentsRequest
,
rather than sending an upload request per adjustment.
Check the quota
guide for
limits on the number of adjustments per request. If you want offline data
diagnostics to group a set of requests
under the same logical job, set the
job_id
of all the
requests to the same value.
Prepare data for upload
For privacy considerations, the following data must be hashed using SHA-256 before being uploaded:
- Email address
- Phone number
- First name
- Last name
- Street address
Don't hash the following data:
- Country
- State
- City
- Zip code
In order to standardize the hash results, you must do the following prior to hashing one of these values:
- Remove leading and trailing whitespaces.
- Convert the text to lowercase.
- Format phone numbers according to the E164 standard.
- Remove all periods (
.
) that precede the domain name ingmail.com
andgooglemail.com
email addresses.

Upload enhanced conversions
The following snippets demonstrate how to construct an enhancement adjustment
that contains an order ID, plus identifiers for email address, phone number, and
physical address, with standardization and hashing applied as required. As a
best practice, include gclid
on the adjustment if it's available.
Add user identifiers to the ConversionAdjustment
Java

Review your uploads
Use offline data diagnostics to review the overall health of your recent uploads. Note that upload success does not necessarily mean the uploads have matches.
When reporting on conversion metrics for your campaigns, refer to Mapping user
interface metrics to correlate Google Ads UI
metrics with Google Ads API reporting fields. You can also query the
conversion_action
resource to view the total
number of conversions and the total conversion value for a given conversion
action.
