    $config = array(
        "env"                 => "sandbox",
        "consumerKey"         => "ss0sD2ANhjvhx_rHU0a6Xf8ROdYa",

    );
    coopSetup($config);

Usage

We recommend using the following helper functions

Check Account Balance

Account Balance Enquiry API will enable you to enquire about your own Co-operative Bank accounts' balance as at now for the specified account number

    $response = coopAccountBalance(
        $messageReference, 
        $accountNumber = null, 
        $callback = null
    );

Check AccountTransactions

Account Transactions Enquiry API will enable you to enquire about your own Co-operative Bank accounts' latest transactions for the specified account number and number of transactions to be returned

    $response = coopAccountTransactions(
        $messageReference, 
        $accountNumber, 
        $NoOfTransactions = '1', 
        $callback = null
    );

Get Exchange Rate

Exchange Rate Enquiry API will enable you to enquire about the current SPOT exchange rate for the specified currencies

    $response = coopExchangeRate(
        $messageReference, 
        $fromCurrencyCode = 'KES', 
        $toCurrencyCode = 'USD', 
        $callback = null
    );

IFT Account To Account Transfer

Internal Funds Transfer Account to Account API will enable you to transfer funds from your own Co-operative Bank account to other Co-operative Bank account(s)

    $response = coopIFTAccountToAccount(
        $messageReference, 
        $accountNumber, 
        $amount, 
        $transactionCurrency = 'KES', 
        $narration = 'Payment', 
        $destinations = array(), 
        $callback = null
    );

PesaLink Send To Account

PesaLink Send to Account Funds Transfer API will enable you to transfer funds from your own Co-operative Bank account to Bank account(s) in IPSL participating banks

    $response = coopPesaLinkSendToAccount(
        $messageReference, 
        $accountNumber, 
        $amount, 
        $transactionCurrency = 'KES', 
        $narration = 'Payment', 
        $destinations = array(), 
        $callback = null
    );

Check Transaction Status

This is a Transaction Status Enquiry Request interface called by an API consumer to APIM to enquire the status of an earlier requested transaction.

    $response = coopTransactionStatus(
        $messageReference, 
        $callback = null
    );

Callback functions

The last OPTIONAL argument in the functions above ($callback) allows you to add a callable function to process the API responses. You can either pass a defined function or a closure

Using A Defined Function

    function processCoopTransactionStatus($response) {
        // Do something with $response
    }
    $response = coopTransactionStatus($messageReference, 'processCoopTransactionStatus');

Using A Closure

    $response = coopTransactionStatus($messageReference, function ($response) {
        // Do something with $response
    });

Callback URL and Reconciling Data

Use the coopReconcile() helper function at your callback URL endpoint to process responses from the API, optionally passing a callable function to process the API responses. You can either pass a defined function or a closure

Using A Defined Function

    function processCoopTransactionStatusResponse($response) {
        // Do something with $response
    }
    $response = coopReconcile('processCoopTransactionStatusResponse');

Using A Closure

    $response = coopReconcile(function ($response) {
        // Do something with $response
    });

Test Cases

As a developer, the test cases will be available to you for download as you are creating the sandbox app.

The test cases are in place to ensure that you have well understood the API structure for requests and responses for our different APIs. These test cases are in an excel spreadsheet that you should fill in with the results from each of the test scenarios that you want to consume.

As the Test cases will cover all the APIs available, you will only be required to carry out the test cases for the APIs you had initially selected.

Go - Live

Once you have already tried out the APIs on our platform and have tested these against our test cases provided, you can make a formal request to go to production.

You will need to have the test cases duly filled, then send an email request, together with these filled in test cases, to our support team who will guide you on the next steps to enable you to get to production.

Send the email request and the test cases to digitalbanking@co-opbank.co.ke
