get https://sandbox-api.spinwheel.io/v1/users//billingDetails
For customers who are not yet using our payments solutions, it can be helpful to access a user's billing details. A GET request to the above endpoint will return a billingDetails object with account numbers and the addresses for all the servicers connected to the user's account. The response may contain higher levels of specificity (such as an account number to make a payment on a particular loan) if the information has been provided by the servicer.
