# Create or retrieve funding instructions for a customer cash balance

Retrieve funding instructions for a customer cash balance. If funding instructions do not yet exist for the customer, new funding instructions will be created. If funding instructions have already been created for a given customer, the same funding instructions will be retrieved. In other words, we will return the same funding instructions each time.
