In some embodiments, a system instrument identifier is a unique identifier for representing a service provider instrument 518 within the exchange platform 102. The system instrument identifier, for example, may include a sequence of numeric, alpha-numeric, any/or any other characters or symbols that represent the service provider instrument 518 to the exchange platform 102 without exposing the persistent credentials 514 of the service provider instrument 518. In some examples, the system instrument identifier may include a UUID. In some examples, the system instrument identifier may include at least one of the system identifiers 512.
