#### Integration type

Email-based counterparty invitation and onboarding.

An Ospree user can request the activation of a counterparty VASP by entering its email address in the Accounts Directory. Ospree sends an automated invitation that directs the counterparty through registration and compliance onboarding.

The counterparty must receive the invitation, register with Ospree, provide the required compliance information, and pass Ospree’s review. Following approval, the inviting company must complete any applicable internal due diligence before initiating Travel Rule exchanges.
