RocketROI allows you the option to update the permissions that you need to create and work with your campaigns.
You will find it on your User Profile, below on the left of the Side Menu.
Then, you just have to choose the platform you want to have permissions to work with on RocketROI.
For example, if you are going to create and work with Shopping campaigns from RocketROI, select the "Google Shopping" channel, and it will ask you to add the Merchant ID.
