In order for Alight Analytics to have access to your Hatch account, you'll need to create a connection on the Connect Page of ChannelMix Control Center.
Clients will need to provide a Username and Password to create the initial connection to pull data from the Hatch API.
Once you create the connection using the username and password, you'll add the ChannelMix profile you would like to use. When you add that profile you'll be asked to add the unique_brand for that profile. The only way that Hatch allows you to obtain this unique_brand_id is by reaching out to your Hatch contact and they should be able to provide you with that Brand Id.
