In some embodiments, the partner interface 402 is an exchange interface for facilitating one or more communications between a partner platform 420 and the exchange platform 102. The partner interface 402 may define one or more communication instructions, message definitions, and/or the like for facilitating one or more request messages and/or response messages between a partner platform 420 and the exchange platform 102. The partner interface 402, for example, may include an API that defines (i) requests to the exchange platform 102 from a computing entity acting as a partner platform 420 and/or (ii) requests from the exchange platform 102 to the partner platform 420. For example, the partner interface 402 may define one or more registration messages, session messages, transaction messages, and/or the like for facilitating an exchange of value for the partner.
