About App ID when selecting Mobile ID of Customer Match

[國谷孝一]

Hello

I would like to ask you about Customer Match.

If I select Mobile ID for Customer Match, I will need to specify the App ID.

What is this App ID used for in Customer Match Processing?

Thank you very much

Hi,

Thank you for reaching out to us. I see that you're wondering what appID is used for in customer match. According to the documentation, the appID is a string that uniquely identifies a mobile application from which the data was collected to AdWords API. This means that the mobile application you specify via the appID will help supply collected data to the API for your CRM based user list. This field is required when creating CrmBasedUserList for uploading mobile advertising IDs. Let me know if you have further questions.

Thank you,
Bryan, Google Ads API Team
