In order for Alight Analytics to have access to your Basis By Centro account, you'll need to create a connection on the Connect Page of ChannelMix Control Center.
In order to create that connection, clients will need to have a username and password with API access. They will also need to have a Client ID and Client Secret. All of these can be obtained by reaching out to your Centro representative. Once you have them you can create the connection in the Control Center. Once the connection is made, you should then see a list of Brands that should have a 1:1 relationship with ChannelMix profiles.
The standard datasets are activatable but as always feel free to submit a request if you have any questions.
