If you are engaging an agency like Discosloth to run Google Shopping ads, you will need to grant access to your Google Merchant Center account, in order for us to configure your product feed.
Sign into Google Merchant Center, and click the Tools icon, then click Account Access.
Click the blue + button, and add the email address (for Discosloth, this is email@example.com). Now, click Add User.
Next, select the access level (for agencies, we will need Admin level in order to link products and make changes to Merchant Center). Click save.
Now, we should have the needed access to your Google Merchant Center account in order to run ads!
