# Overview

The File Payments API Profile describes the flows for File Payments, which allows a Payment Initiation Service Provider ('PISP') to:

  • Register an intent to stage a file-payment consent.
  • Subsequently submit the file-payment for processing.
  • Optionally retrieve the status of a file-payment consent or file-payment resource.

This profile should be read in conjunction with a compatible Read/Write Data API Profile, a compatible Payment Initiation API Profile and compatible individual resources.

# Document Overview

This document consists of the following parts:

# Overview

File Payments allow a file of payments to be uploaded to an ASPSP for payment initiation.

The high-level flow for file-payments follow the flow for all other payment-order types (as described in the Basics > Overview Section of Payment Initiation API Profile) however, with an additional step to upload the file. The step for staging the payment-order consent is broken into two steps:

  • POST metadata of the file-payment for payment initiation.
  • POST the file of the file-payment for payment initiation.

# Steps

Step 1: Agree File Payment-Order Initiation.

Step 2a: Setup File Payment-Order Consent (Metadata):

  • The PISP connects to the ASPSP that services the PSU's payment account and creates a new file-payment-consent resource. This JSON message contains the Metadata of the file payments file. The ASPSP responds with a ConsentId.
  • This step is carried out by making a POST request to the file-payment-consent resource.

Step 2b: Setup File Payment-Order Consent (Upload File):

  • The PISP uploads the payment file to the file-payment-consent endpoint with ConsentId obtained in Step 2a.
  • ASPSP verifies the payment file against the hash of payment file received in the file-payment-consent Metadata in Step 2a.
  • ASPSP responds with 200 OK.
  • This step completes the file-payment-consent creation.

Step 3: Authorise Consent.

Step 4: Create Payment-Order.

Step 5: Get Consent/Payment-Order/Payment-Details Status:

  • A PISP may optionally request the Status of the file-payment-consent.
  • A PISP may optionally request File uploaded to file-payment-consent, for verification.
  • A PISP may optionally request the Status of the file-payment.
  • A PISP may optionally request a report in a file format, on the status of the individual payments in file-payments, if the ASPSP makes this available.
  • A PISP may optionally request the detail status of the individual payments in file-payments, if the ASPSP makes this available.
