If you would like OnlineNaira to help install this API into your website, please send us an email here.

PHP API - Client Side.

Below is a description for all fields which you can use. For successful payment process you should use the following parameters:
member* OnlineNaira Username - this is one parameter that the user cannot change in OnlineNaira. Once set at signup, it remains the same throughout the life of the account. It is unique and it forms the most important identification for members. This parameter must be set for your integration to work.

  use "donation" if this is a donation
  use "subscription" if this product is subscription and repeats
  use "payment" if this is a simple payment transaction

pid unique transaction identification or some number that uniquely identifies the event - this is optional.

OnlineNaira will send you an automated email notification after every successful payment, but if you want to have a deeper integration with OnlineNaira, the unotify must be set to a url that will handle call-back parameters.
* these parameters are mandatory.

Notes - All payments in OnlineNaira are in Naira (NGN), but you should display your local currency in your shop while setting the country parameter to the 3 digit ISO code (ISO-4217 ) before parsing to OnlineNaira.

Accept Payments

With OnlineNaira API, you will get paid from buyer's account balance, but buyer would be able to fund their account with cash, bank wire or any cards issued in Nigeria. They would also be able to fund their accounts with eCurrencies such as bitcoins, ethereum, Neteller, PerfectMoney, etc

Here's an example of the api implementation if you are looking to receive deposits on your website.

<form method=post action="">
<input type=hidden name=member value="ADESIYAN">
<input type=hidden name=action value="payment">
<input type=hidden name=product value="Deposit for Service">
<input type=text name=price value="">
<input type=hidden name=country value="NGN">
<input type=hidden name=apikey value="adesiyan">
<input type=hidden name=ureturn value="">
<input type=hidden name=unotify value="">
<input type=hidden name=ucancel value="">
<input type=hidden name=comments value="Deposit for Service">
<input type=image src="">

Using Other Currencies

If you prefer to collect money with OnlineNaira in other currencies, pls be sure to set the country parameter.

Example - To display the Ghanaian Currency, USD, use the following line
<input type="hidden" name="country" value="USD">

It is better to display $, £ or € on the merchant website and let the OnlineNaira API auto convert the money to NGN. NGN fluctuates, but our API tracks the fluctuation so the correct NGN/$/£/€ conversion is used at all times.

Automated Withdrawals

curl url -
Four fields are required
*secret_apikey - this is different from the apikey, this is a secret key, and should be kept private. Pls login to generate key here -
*sender - username of the sender
*receiver - username of the receiver
*amount - amount to send in NGN

The auto withdrawal in our API will enable all your users to do withdrawals by themselves when they want. The withdrawal will initially happen on your platform without calling the OnlineNaira API. When you confirm from your backend, our API would be called (for auto withdrawal, our API is called once) and user is paid. This gives you complete control of the withdrawal process without login into OnlineNaira.

Currency Setting

If you sell in any currency order than the Nigerian Naira (NGN), you should set the country parameter. The OnlineNaira API has built-in features to allow you to sell in any currency, but you will need to set the country parameter to tell OnlineNaira that you are selling in a currency order than the Naira. If you do not set the country parameter, OnlineNaira will treat all your receipts as if you were selling in Naira (NGN). Alternatively, if you sell in dollars ($), please set your action
