In Google Ads, a [conversion](https://support.google.com/google-ads/answer/6365) is a valuable user action---such as purchasing a product, submitting a lead form, calling your business, or visiting a physical store---that follows an ad interaction. [Conversion tracking](https://support.google.com/google-ads/answer/1722022) measures these customer interactions so you can evaluate campaign performance and optimize automated bidding. The Google Ads API lets you programmatically configure conversion actions, import offline conversion events, enhance or adjust recorded conversions, group actions into bidding and lifecycle goals, and monitor upload diagnostics. ## Choose your conversion workflow Use the following table to identify the [`ConversionActionType`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionActionTypeEnum.ConversionActionType.md.txt), API service, and implementation guide for your use case: | Task | Conversion action type | API service or resource | Implementation guide | |---|---|---|---| | **Verify account setup and create a conversion action** | `UPLOAD_CLICKS`, `WEBPAGE`,

[`NotAllowlistedError.CUSTOMER_NOT_ALLOWLISTED_FOR_THIS_FEATURE`](https://developers.google.com/google-ads/api/reference/rpc/v26/NotAllowlistedErrorEnum.NotAllowlistedError.md.txt#customer_not_allowlisted_for_this_feature) error if your Google Cloud project (or legacy [developer > token](https://developers.google.com/google-ads/api/docs/api-policy/developer-token), sunset on September 9, 2026) had no offline click conversion upload activity between December 17, 2025 and June 15, 2026. To integrate offline click conversions, enhanced conversions for leads, or store sales, use the **Data Manager API** ([offline conversions guide](https://developers.google.com/data-manager/api/devguides/events/google-ads/offline.md.txt) and [store sales guide](https://developers.google.com/data-manager/api/devguides/events/google-ads/store-sales.md.txt)). For details, see [Feature > deprecations](https://developers.google.com/google-ads/api/docs/deprecations#feature-deprecations). ## End-to-end conversion lifecycle A complete conversion management integration in the Google Ads API follows four stages: 1. **Verify account setup and create conversion actions** : Query [`Customer.conversion_tracking_setting`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionTrackingSetting.md.txt) to confirm the effective conversion account (`google_ads_conversion_customer`), verify that conversion tracking is active, configure [user consent](https://developers.google.com/google-ads/api/docs/conversions/getting-started.md.txt#configure_consent), and create a [`ConversionAction`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAction.md.txt) with the target [`ConversionActionType`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionActionTypeEnum.ConversionActionType.md.txt) and [`ConversionActionCategory`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionActionCategoryEnum.ConversionActionCategory.md.txt). 2. **Import conversion events** : Stream offline click or call conversions using [`ConversionUploadService`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadService.md.txt) with `partial_failure` set to `true`, supplement website conversions with `ENHANCEMENT` adjustments using [`ConversionAdjustmentUploadService`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAdjustmentUploadService.md.txt), or batch-upload store sales using [`OfflineUserDataJobService`](https://developers.google.com/google-ads/api/reference/rpc/v26/OfflineUserDataJobService.md.txt). 3. **Adjust and optimize conversions** : Retract or restate recorded conversions using [`ConversionAdjustmentUploadService`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAdjustmentUploadService.md.txt), attach [`ConversionCustomVariable`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionCustomVariable.md.txt) metadata, apply [conversion value rules](https://developers.google.com/google-ads/api/docs/conversions/conversion-value-rules.md.txt), and organize actions into [conversion goals](https://developers.google.com/google-ads/api/docs/conversions/goals/overview) and [lifecycle goals](https://developers.google.com/google-ads/api/docs/conversions/goals/lifecycle-goals.md.txt) to control bidding optimization. 4. **Monitor diagnostics and report performance** : Query [`offline_conversion_upload_client_summary`](https://developers.google.com/google-ads/api/fields/v26/offline_conversion_upload_client_summary.md.txt) and [`offline_conversion_upload_conversion_action_summary`](https://developers.google.com/google-ads/api/fields/v26/offline_conversion_upload_conversion_action_summary.md.txt) to inspect upload processing status and partial failure alerts. Query the [`customer`](https://developers.google.com/google-ads/api/fields/v26/customer.md.txt) or [`campaign`](https://developers.google.com/google-ads/api/fields/v26/campaign.md.txt) resources (optionally segmented by `segments.conversion_action`) to compare the `metrics.conversions` and `metrics.all_conversions` metrics, or query the [`conversion_action`](https://developers.google.com/google-ads/api/fields/v26/conversion_action.md.txt) resource to inspect `metrics.all_conversions` and last-conversion timestamps. ## Quickstart: Verify setup, create actions, and check health The following examples show the three most common queries and mutations needed to initialize and monitor conversion tracking. ### 1. Verify conversion tracking settings with GAQL Before creating a [`ConversionAction`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAction.md.txt) or uploading events, query the [`customer`](https://developers.google.com/google-ads/api/fields/v26/customer.md.txt) resource by using [`GoogleAdsService.SearchStream`](https://developers.google.com/google-ads/api/reference/rpc/v26/GoogleAdsService/SearchStream.md.txt) to determine which account manages conversions (`google_ads_conversion_customer`), whether customer data terms are accepted, and whether account-level enhanced conversions are turned on ([`EnhancedConversionsConfig`](https://developers.google.com/google-ads/api/reference/rpc/v26/EnhancedConversionsConfigEnum.EnhancedConversionsConfig.md.txt)): ```sql SELECT customer.conversion_tracking_setting.conversion_tracking_id, customer.conversion_tracking_setting.conversion_tracking_status, customer.conversion_tracking_setting.cross_account_conversion_tracking_id, customer.conversion_tracking_setting.google_ads_conversion_customer, customer.conversion_tracking_setting.accepted_customer_data_terms, customer.conversion_tracking_setting.enablement_setting, customer.conversion_tracking_setting.effective_enablement_setting FROM customer ``` Extract the `{customer_id}` from the `customers/{customer_id}` resource name returned in `google_ads_conversion_customer`, and issue all subsequent [`ConversionActionService`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionActionService.md.txt) and [`ConversionUploadService`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionUploadService.md.txt) requests against that customer ID. For full setup and cross-account hierarchy details, see [Getting started](https://developers.google.com/google-ads/api/docs/conversions/getting-started). ### 2. Create a conversion action Use [`ConversionActionService.MutateConversionActions`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionActionService/MutateConversionActions.md.txt) to create a [`ConversionAction`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAction.md.txt). The following example creates an `UPLOAD_CLICKS` conversion action with custom value and lookback settings: ### Java ```java private void runExample(GoogleAdsClient googleAdsClient, long customerId) { // Creates a ConversionAction. ConversionAction conversionAction = ConversionAction.newBuilder() // Note that conversion action names must be unique. If a conversion action already // exists with the specified conversion_action_name the create operation will fail with // a ConversionActionError.DUPLICATE_NAME error. .setName("Earth to Mars Cruises Conversion #" + getPrintableDateTime()) .setCategory(ConversionActionCategory.DEFAULT) .setType(ConversionActionType.WEBPAGE) .setStatus(ConversionActionStatus.ENABLED) .setViewThroughLookbackWindowDays(15L) .setValueSettings( ValueSettings.newBuilder() .setDefaultValue(23.41) .setAlwaysUseDefaultValue(true) .build()) .build(); // Creates the operation. ConversionActionOperation operation = ConversionActionOperation.newBuilder().setCreate(conversionAction).build(); try (ConversionActionServiceClient conversionActionServiceClient = googleAdsClient.getLatestVersion().createConversionActionServiceClient()) { MutateConversionActionsResponse response = conversionActionServiceClient.mutateConversionActions( Long.toString(customerId), Collections.singletonList(operation)); System.out.printf("Added %d conversion actions:%n", response.getResultsCount()); for (MutateConversionActionResult result : response.getResultsList()) { System.out.printf( "New conversion action added with resource name: '%s'%n", result.getResourceName()); } } } ``` ### C# ```c# public void Run(GoogleAdsClient client, long customerId) { // Get the ConversionActionService. ConversionActionServiceClient conversionActionService = client.GetService(Services.V26.ConversionActionService); // Note that conversion action names must be unique. // If a conversion action already exists with the specified name the create operation // will fail with a ConversionAction.DUPLICATE_NAME error. string ConversionActionName = "Earth to Mars Cruises Conversion #" + ExampleUtilities.GetRandomString(); // Add a conversion action. ConversionAction conversionAction = new ConversionAction() { Name = ConversionActionName, Category = ConversionActionCategory.Default, Type = ConversionActionType.Webpage, Status = ConversionActionStatus.Enabled, ViewThroughLookbackWindowDays = 15, ValueSettings = new ConversionAction.Types.ValueSettings() { DefaultValue = 23.41, AlwaysUseDefaultValue = true } }; // Create the operation. ConversionActionOperation operation = new ConversionActionOperation() { Create = conversionAction }; try { // Create the conversion action. MutateConversionActionsResponse response = conversionActionService.MutateConversionActions(customerId.ToString(), new ConversionActionOperation[] { operation }); // Display the results. foreach (MutateConversionActionResult newConversionAction in response.Results) { Console.WriteLine($"New conversion action with resource name = " + $"'{newConversionAction.ResourceName}' was added."); } } catch (GoogleAdsException e) { Console.WriteLine("Failure:"); Console.WriteLine($"Message: {e.Message}"); Console.WriteLine($"Failure: {e.Failure}"); Console.WriteLine($"Request ID: {e.RequestId}"); throw; } } ``` ### PHP ```php public static function runExample(GoogleAdsClient $googleAdsClient, int $customerId) { // Creates a conversion action. $conversionAction = new ConversionAction( [ // Note that conversion action names must be unique. // If a conversion action already exists with the specified conversion_action_name // the create operation will fail with a ConversionActionError.DUPLICATE_NAME error.

#### REST request To create the same [`ConversionAction`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionAction.md.txt) over REST, send a `POST` request to [`ConversionActionService.MutateConversionActions`](https://developers.google.com/google-ads/api/reference/rpc/v26/ConversionActionService/MutateConversionActions.md.txt): ```console POST https://googleads.googleapis.com/v26/customers/{customer_id}/conversionActions:mutate ``` ```json { "operations": [ { "create": { "name": "Earth to Mars Cruise Conversion", "type": "UPLOAD_CLICKS", "category": "DEFAULT", "status": "ENABLED", "primaryForGoal": true, "countingType": "ONE_PER_CLICK", "clickThroughLookbackWindowDays": "60", "valueSettings": { "defaultValue": 23.41, "defaultCurrencyCode": "USD", "alwaysUseDefaultValue": true } } } ] } ``` Once your conversion action is `ENABLED`, import conversion events or enhancements using the workflow for your conversion source (see [Import conversion events](https://developers.google.com/google-ads/api/docs/conversions/overview#import-guides)). ### 3. Monitor offline conversion upload health After uploading click conversions, call conversions, or conversion adjustments, query [`offline_conversion_upload_client_summary`](https://developers.google.com/google-ads/api/fields/v26/offline_conversion_upload_client_summary.md.txt) to check overall job status, success and pending rates, and error breakdowns across your recent uploads: ```sql SELECT offline_conversion_upload_client_summary.client, offline_conversion_upload_client_summary.status, offline_conversion_upload_client_summary.total_event_count, offline_conversion_upload_client_summary.successful_event_count, offline_conversion_upload_client_summary.success_rate, offline_conversion_upload_client_summary.pending_event_count, offline_conversion_upload_client_summary.pending_rate, offline_conversion_upload_client_summary.last_upload_date_time, offline_conversion_upload_client_summary.alerts FROM offline_conversion_upload_client_summary ``` Query [`offline_conversion_upload_conversion_action_summary`](https://developers.google.com/google-ads/api/fields/v26/offline_conversion_upload_conversion_action_summary.md.txt) for conversion action-level diagnostics (see [Monitor offline data diagnostics](https://developers.google.com/google-ads/api/docs/conversions/upload-summaries)), and refer to [Troubleshoot conversion imports](https://developers.google.com/google-ads/api/docs/conversions/troubleshooting) to resolve specific error codes. ## Guide directory by lifecycle stage Explore the full set of conversion management guides organized by lifecycle stage: ### 1.
