Microsoft Ads: Permissions issues guide

In this article, we will guide you on how to solve login failures and permission errors when connecting your Hub Account to Microsoft Ads

If you're encountering login failures or permission-related errors when trying to connect your Hub Account to Bing Ads through Dataslayer, the issue is often due to changes Microsoft made in mid-2021 to the authentication process.

How to successfully log in to Microsoft Ads

The login error is usually due to permission settings that need to be configured in Microsoft Azure. If the user account you're using to connect to Microsoft Ads through Dataslayer does not have the API User role assigned, Microsoft blocks the authentication attempt.

Assign the "API User" Role in Azure

To resolve this, follow these steps:

1. Access your Azure Active Directory associated with your Microsoft Ads account.

2. Locate the user account you're using for the connection.

3. Assign the "API User" role to this account.

Once the "API User" role is assigned, try logging in again. The process should now complete successfully without further issues.

If the issue persists after assigning the "API User" role, contact your IT administrator to confirm that the role has been correctly applied and that there are no other configuration issues.
