Welcome to M-Pesa PHP API

This project aims to provide an easy-to-use and up-to-date PHP wrapper for the M-Pesa Mozambique API.

Target version of M-Pesa API: v1x

Installation

Install using composer:

composer require abdulmueid/mpesa

Usage

1. Load the configuration from file.

   $config = \abdulmueid\mpesa\Config::loadFromFile('/path/to/config.php');

   See sample configuration file in examples folder.

2. Create a Transaction using the configuration.

   $transaction = new \abdulmueid\mpesa\Transaction($config);

3. Execute API operations and pass appropriate parameters.

   1. Initiate a C2B payment collection.

      $c2b = $transaction->c2b(
          float $amount,
          string $msisdn,
          string $reference,
          string $third_party_reference
      );

   2. Initiate a B2C payment.

      $b2c = $transaction->b2c(
          float $amount,
          string $msisdn,
          string $reference,
          string $third_party_reference
      );

   3. Initiate a B2B payment.

      $b2b = $transaction->b2b(
           float $amount,
           string $receiver_party_code,
           string $reference,
           string $third_party_reference
      );

   4. Initiate a reversal.

      $reversal = $transaction->reversal(
          float $amount,  
          string $transaction_id,
          string $third_party_reference
      );

   5. Query a transaction.

      $query = $transaction->query(
          string $query_reference,
          string $third_party_reference
      );

4. Check Response

   All transactions return the TransactionResponse object. The object has the following public methods:

   1. getCode() - Returns the response code i.e. INS-0

   2. getDescription() - Returns the description.

   3. getTransactionID() - Returns the transaction ID.

   4. getConversationID() - Returns the conversation ID.

   5. getTransactionStatus() - Returns the transaction status. Only populated when calling the query() transaction.

   6. getResponse() - Returns the full response JSON object as received from M-Pesa servers. Good for debugging any issues or undocumented behaviors of the M-Pesa API.

In a typical scenario, code to check for successful transactions should be as follows:

$c2b = $transaction->c2b(...);

if($c2b->getCode() === 'INS-0') {
    // Transaction Successful, Do something here
}

Testing

This repo provides Unit Tests to validate the objects and their interaction with M-Pesa.

To run tests,

1. Open the phpunit.xml file and add the require credentials/parameters as supplied by M-Pesa.
2. Run phpunit
3. Check the handset for USSD prompts to approve test transactions.

All tests use 1MT as the test amount.
