Overview

This release introduces significant updates and improvements to the API, enhancing transaction processing, standardizing data formats, and expanding support for payouts and pay-ins across multiple currencies.

​
Breaking Changes

The API has been upgraded to Version 4 (V4) to improve stability, security, and performance. This version includes some changes that should be considered when migrating from the previous version.

​
Standardized Amount Handling

  • Updated both collection and disbursement APIs to use absolute amounts.
    Previously: Payout amounts were multiplied by 100.
    Sample V3 API Payout Request for 50 XOF:
{
        "client_id": "client_id",
        "params": {
            "amount": "5000",
            "city": "CustomerCity",
            "client_callback_url": "https://webhook.site/url",
            "country_id": "2",
            "currency": "XOF",
            "email": "john.doe@example.com",
            "first_name": "John",
            "last_name": "Doe",
            "line1": "CustomerStreet",
            "mobile": "22991600649",
            "mtn": [
                {
                    "phone_number": "22991600649"
                }
            ],

            "payment_reference": "",
            "postal_code": "192.0.0.1",
            "third_party_reference_1": ""
        },
        "salt": "mySalt123",
        "sender": "Integration name",
        "timestamp": "Timestamp value",
        "signature":"XxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxX"
    }
Now: All amounts are passed in their absolute form to maintain consistency across all transactions.

                }
            ],
            "payment_method_type": "mtn",
