Create an exchange for an account #

This section contains information on how to create an exchange for a reseller partner or client account. The creation of an exchange serves as the “hand-shake” between Dwolla and a trusted ecosystem partner. The creation of an exchange requires a _link to the exchange partner and tokenized data which encapsulates limited permissioned access between an ecosystem partner and Dwolla.
