Initiate Transfers

Single Transfers

To initiate a single transfer, you will need to send a request to the endpoint below:

This endpoint is protected with OAuth 2.0 Bearer token. To find out more about authorization for Monnify endpoints, check Here.

Endpoint URL: {{base_url}}/api/v2/disbursements/single

HTTP Method: POST

The {{base_url}} for the test is https://sandbox.monnify.com but when you go live, it changes to the live URL

Below is a sample request for initiating a single transfer:

Initiate Transfer (Single)

{
    "amount": 20,
    "reference":"ben9-jlo00hdhdjjdfjoj--i",
    "narration":"Test01",
    "destinationBankCode": "057",
    "destinationAccountNumber": "2085096393",
    "currency": "NGN",
    "sourceAccountNumber": "8016472829",
    "destinationAccountName": "Marvelous Benji"
}

If the merchant does not have Two Factor Authentication (2FA) enabled, the transaction will be processed instantly and the response will be as follows:

Initiate Transfer (Single) Response 2FA Disabled

{
    "requestSuccessful": true,
    "responseMessage": "success",
    "responseCode": "0",
    "responseBody": {
        "amount": 20,
        "reference": "ben9-jlo00hdhdjjdfjoj--i",
        "status": "SUCCESS",
        "dateCreated": "2022-11-03T14:13:38.140+0000",
        "totalFee": 0.00,
        "sessionId": "090405221103151339936348270655",
        "destinationAccountName": "Marvelous Benji",
        "destinationBankName": "Zenith bank",
        "destinationAccountNumber": "2085096393",
        "destinationBankCode": "057"
    }
}

If the merchant has Two Factor Authentication (2FA) enabled, a One Time Password (OTP) will be sent to the designated email address(es). That OTP will need to be supplied via the VALIDATE OTP REQUEST before the transaction can be approved. If 2FA is enabled, the response will be as follows:

Initiate Transfer (Single) Response 2FA Enabled

{
    "requestSuccessful": true,
    "responseMessage": "success",
    "responseCode": "0",
    "responseBody": {
        "amount": 20,
        "reference": "ben9-jlo00hdhdjjdfjoji",
        "status": "PENDING_AUTHORIZATION",
        "dateCreated": "2022-11-03T14:11:12.659+0000",
        "totalFee": 0.00,
        "destinationAccountName": "Marvelous Benji",
        "destinationBankName": "Zenith bank",
        "destinationAccountNumber": "2085096393",
        "destinationBankCode": "057"
    }
}

To simulate a failed disbursement transaction on the sandbox environment, you should use this destination account number: 0035785417 and destination bank code: 044. Here is a sample request:

Initiate Transfer (Single) Failed Disbursement Transaction Request

The response will be as follows:

Initiate Transfer (Single) Failed Disbursement Transaction Response

Processing Transfers Asynchronously

You can easily process transfer to your users asynchronously (by simply setting the “async” parameter to true in your request body) so that your server doesn’t have to wait for Monnify to get the final status of the transfer. When transfers are processed asynchronously, a pending status is returned in the response body, so we recommend that you have a disbursement webhook setup on your end(see here for setup; Webhooks) to receive the final status of the transfer. However you can also requery the transfer to check its status(Transfer Status).

Bulk Transfers

To initiate a bulk transfer, you will need to send a request to the endpoint below:

This endpoint is protected with OAuth 2.0 Bearer token

Bulk transfers allows you send a single request with a list of disbursements you want to be processed. Below is a sample request for initiating a bulk transfer

Initiate Transfer (Bulk)

If the merchant does not have Two Factor Authentication (2FA) enabled, the transaction will be processed instantly and the response will be as follows:

Initiate Transfer (Bulk) Response 2FA Disabled

If the merchant has Two Factor Authentication (2FA) enabled, a One Time Password (OTP) will be sent to the designated email address(es). That OTP will need to be supplied via the VALIDATE OTP REQUEST before the transaction can be approved. If 2FA is enabled, the response will be as follows:

Initiate Transfer (Bulk) Response 2FA Enabled
