This document summarizes a webinar about implementing APIs that interoperate with ISO 20022. The webinar discussed how ISO 20022 and API payments infrastructure will coexist and need to be aligned. It provided an example API for making a credit transfer or payment initiation. It also demonstrated applying an ISO 20022 and SEPA business rules policy to API requests and responses using an API platform. The webinar emphasized designing APIs aligned with ISO 20022 and emerging standards, defining business rules, and applying rules at the API layer for compliance.

• For ISO 20022 and emerging API standards
• For specific payments infrastructures e.g. SEPA
• For your own bank, and specific services at the bank
• Publish API and rules documentation
• Apply the rules at the API Layer
