We are encountering an "Invalid Provider ID" error when trying to link our mobile measurement platform to Google Ads for app conversion tracking. This occurs in the Google Ads UI when selecting "Other provider" as the "App analytics provider" and entering our Google Ads Manager Account Customer ID as the "Provider ID," as described in the official Google documentation.

Problem:

When attempting to link as "Other provider," the Google Ads UI returns the error: "The Provider ID that you entered isn't valid." This happens specifically when we enter our 10-digit Google Ads Manager Account Customer ID (used for our Google Ads API developer token) into the "Enter your provider's ID" field.:

"The Provider ID that you entered isn't valid."

This error occurs specifically when entering the Google Ads Manager Account Customer ID as the "Provider ID" after selecting "Other provider" from the "App analytics provider" dropdown during the Google Ads UI linking process. This process is described in the official Google documentation (linked below).

Steps to Reproduce:

1. In the Google Ads UI, navigate to Conversion actions.

2. Select "+ New conversion action."

3. Choose "App" as the conversion source.

4. Select "Third-party app analytics."

5. Choose the relevant app platform (e.g., "Google Play").

6. Select the specific app.

7. In the "App analytics provider" dropdown, choose "Other provider."

8. In the "Enter your provider's ID" field, enter the 10-digit Customer ID of our (Linkrunner's) Google Ads Manager Account (the account used to obtain our Google Ads API developer token). We are entering this ID without dashes.

9. Click "Create link ID."

10. Error: The message "The Provider ID that you entered isn't valid." is displayed.

Official Documentation Reference:

We are following the official Google documentation for App Conversion Tracking and Remarketing API, specifically the section on Link IDs. The documentation explicitly states:

"To create a link ID associated with your unique developer token, select Other provider from the app analytics provider dropdown. In the input box labeled Enter your provider's ID enter the external customer ID associated with the Google Ads manager account where you applied for your developer token. Enter the ID without dashes (ex. 1234567890 for an account ID shown as 123-456-7890 in the Google Ads UI)."

Official Documentation Link:

We understand from this documentation that the "Provider ID" should be our Google Ads Manager Account's Customer ID. We are encountering an error despite following these instructions.

Context:

We are trying to understand why we are getting this "Invalid Provider ID" error. We have verified the following:

• Correct Customer ID: We have confirmed multiple times that we are using the accurate 10-digit Customer ID of our Google Ads Manager Account.

• ID Format: We are entering the ID without dashes, as instructed.

• Cross-Customer Issue: This issue is reproducible across multiple customer Google Ads accounts, indicating it is not specific to a single account configuration.

• Multiple Attempts: We have retried the linking process several times to ensure accuracy.
