Onboarding a Proxy Directory Operator onto Nexus

The PDO must provide Nexus with reference data on the available address types and input fields

Nexus needs to be aware of the different address types (such as IBAN, account, mobile) and address inputs available in each country, so that it can provide this information to Source PSPs through the Nexus APIs. Therefore when a new IPSO (or proxy service) is onboarded with Nexus, the IPSO must provide Nexus with reference data describing each address type and the input fields (address inputs) for that address type. This information can be provided via the Nexus Service Desk or APIs.

The IPS Operator is responsible for ensuring that the data is kept up to date.

PDO must onboard with the local IPS Operator

The Nexus Scheme expects the IPS Operator to take on the responsibility for connecting its instance of the Nexus Gateway to the domestic proxy directory, particularly where:

• The IPS Operator and the PDO are the same entity, AND/OR

• In each country that the IPS Operator provides payment services to, there is only one PDO

Cases where there are multiple IPSOs or multiple Proxy Directories in a particular country or jurisdiction may need to be handled differently. The approach to this scenario will be developed in a future phase of Nexus development.
