  title: Ozone Connect - Service Initiation APIs
  description: |
    This document provides an API description in [OpenAPI](https://spec.openapis.org/oas/v3.0.1.html) 
    for Service Initiation APIs for Ozone Connect.

    These APIs should be implemented by a Financial Institution so that Ozone can deliver Service Initiation capabilities to TPPs

    #### Changes#### Changes in VersionRelease 2024.37.0

    * Added `default` response to each operation to aid understanding of error handling requirements.

    * Added missing `description` properties through the document.

    * Removed `additionalProperties: true` as not required and causes tooling issues

    #### Changes in Version 2024.34.1

    * Removed propagateError field from the Error object.

    * Update exchangeRate and rateType properties

    * Refactored Security Scheme Objects to use common definitions across all API Hub APIs
    
    * Implemented the correct Security Requirements for this API description, reflecting security patterns available in API Hub

    #### Changes in Version 2024.34

    * Introduced new endpoint Get /payment-consents/{consentId}/refund.

    * Cosmetic changes - Request Response Changes

      summary: Make a payment
      description: |
        This API is called by Ozone Connect to instruct a Financial Institution to initiate a payment once it has received a payment
        instruction from a TPP that has passed all local validations.

        The Financial Institution must process the payment and indicate a failure response (if the payment fails technical validation) or a
        success response (if the payment passess technical validation and is submitted to the payment rails for processing)

        The Financial Institution must generate a unique `PaymentId` that can be sent on to the TPP as a reference for the payment.

        If the underlying consent has been patched with a `bankConnectToken`, then the token is passed in as the authorization header.
