Hi Frank,
I work with Yasar and will assist you. To access a customer's account with your application and use your own developer token to make API calls to manage that customer, you can first ask to
link their account to your manager account. When your request is granted your manager account with its developer token can then access the customer's account using your developer token, no need to give out your developer token to anyone if your customer is requesting access through your server app.
You can limit each customer to only access their accounts by putting in
login customer Id of the user's topmost manager account in each call you make for a customer.
To initiate this permission you don't need Oauth flow for a customer, the customer doesn't need their own access to API either. They can accept invitations for your manager account to manage their accounts in the UI by going to tools and settings -> access and security -> MANAGERS.
Feel free to get back to us.
Regards,
