This section describes how PSPs should send and receive payments, in significant detail. It is intended for developers who will integrate a PSP's app and payment processing systems with Nexus.

For a simpler overview of how the Nexus payment process would appear to an end-user, and how the payment itself is processed, please see [SHORT REPORT].

For the payment process from the perspective of the PSP, continue to:

  • Sending payments requires updates to a PSP's app, as well as changes to the data included ina payment instruction

  • Receiving payments requires updates to the PSP's payment processing and sanctions screening workflows

For a much more detailed description on how payments are processed once they have been sent by the PSP to the local IPS, see:
