Mambu Payments (formerly Numeral) enables customers to migrate and manage their historical payment operations, giving them full visibility of their payment history and control over R transactions.

Process

Mambu Payments (formerly Numeral) offers 4 CSV file templates used to import payment orders, incoming payments, return requests, and direct debit mandates. The remaining of this guide explains how to populate these files.

Once populated and received, Mambu Payments (formerly Numeral) will import, test, and validate data in a test environment before repeating the import into a production environment.

Payment types

Use cases

Credit transfer / instant payments

Importing a credit transfer incoming payment from <13 months ago to potentially receive a Recall / RRO on it
Importing a credit transfer incoming payment from <3 days ago to potentially send a Return on it (SCT only)
Importing a credit transfer payment order from <3 days ago to potentially receive a Return on it (SCT only)
Importing a credit transfer payment order from <13 months ago to potentially send a Recall / RRO on it
Importing an incoming return request (Recall / RRO) from <15 days to reply to it with a positive / negative response
Importing an outgoing return request (Recall / RRO) from <15 days to be sure to properly catch its positive / negative response

Direct debit payments

Importing direct debit mandates (outgoing or incoming)
Importing a direct debit incoming payment from <13 months ago to potentially send a Return / Refund on it
Importing a direct debit incoming payment from <5 days ago to potentially receive a reversal on it
Importing a direct debit payment order <13 months ago to potentially receive a Return / Refund on it
Importing a direct debit payment order from <5 days ago to potentially send a reversal on it

CSV templates

Templates contain mandatory and optional columns. See the full description of each columns for import type below
Each entry must contain an id column filled with a unique internal ID (ideally a UUID v4, but it can also be a custom format). Return requests will be imported after payment orders and incoming payments, as their related_payment_id column must reference the id column of payment orders or incoming payments previously imported
Files can contain up to 100,000 entries each
CSV separator used is ";". Make sure to escape this character or encapsulate all strings that could include this character with double quotes
