This section explains how to execute payouts using Niobi’s Payment API, covering various payment channels and the payout process.

To start making payments using these methods, ensure that your Niobi account is set up and verified. Refer to the ‘Setting up a Niobi Account’ section in the Getting Started section for detailed steps on account creation and setup.

​

You will then generate a signature using the parameters above and proceed to make an api request using the payload. On successful payment, you will receive a callback response with the transaction details. Please find a detailed description of the callback response under Callback URL Section.

Please note that all live transactions made through our API are subject to a transaction fee.

Sample Flow

This section provides a high-level overview of how to integrate with the Disbursements API.

1

Initiating the Unified Disbursements API Request

To begin, generate a signature for your api request using the generate signature api endpoint and initiate a payout transaction by making an API request.

Sample API Request

{
        "client_id": "client_id",
        "params": {
            "amount": "500",
            "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_method_type": "mtn",
            "payment_reference": "",
            "postal_code": "192.0.0.1",
            "third_party_reference_1": ""
        },
        "salt": "mySalt123",
        "sender": "Integration name",
        "timestamp": "Timestamp value",
        "signature":"XxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxX"
    }

Handling Transaction Status

Once the transaction has been processed, you have two options for managing the transaction status:

  1. Receiving a Callback. A callback response containing the transaction details will be sent to your configured URL. You can set up an endpoint on your front end to handle this callback and update the user interface accordingly, such as displaying success or failure messages based on the transaction outcome. See more about callback responses here

    Sample Callback Response

    "client_id": "Your client id",
"params": {
"account": "80xxxxx3",
"account_number": "",
"amount": 10,
"currency" : "KES",
"fee": 5,
"message": "Payment was transferred successfully.",
"mobile": "254123456789",
"paybill_number": "",
"payee": "JohnDoe 123",
"payment_channel": "Send Money",
"payment_reference": "OID51",
"payoutId": "bd8f51a2-xxxx-xxxx-xxxx-xxxxx9a",
"ref": "SII6ZH9PU0",
"statusCode": "000000",
"third_party_reference_1": "TRANS1",
"third_party_reference_2": null,
"transaction_date": "2024-09-18 00:00:00",
"transaction_detail": "Disbursement made through M-Pesa Send Money",
"type": "Pay out"
},
"salt": "salt value",
"sender": "Integration name",
"timestamp": 123,
"signature": "7xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxb"
}

  2. Constantly Querying Transaction Status. Alternatively, you can query the transaction status endpoint periodically (recommended for 2 minutes) to check for updates on the transaction status.
