HELP: PowerBI table API export to Marketo

Hello,

I have a table built in PowerBI from two different datasets (user data and sales data connected together with email address) that I need to export into Marketo, I am building an automated email program that triggers emails upon a user hitting certain milestones. The data is updated daily into PowerBI and want to attach the fields/columns into Marketo as custom fields. What is the best way to get this data imported into Marketo from PowerBI? How can I automate this data gathering process? I have read that a Rest API would complete this but need clarification and assistance.  Any and all help is appreciated!

Thank you in advance.
