"edwinmugendi/sapamapay": "master"

Run composer update to pull down the latest version.

Or run

composer require edwinmugendi/sapamapay

Without composer. Download the source code and require_once the autoload.php

require_once __DIR__ . '/../vendor/autoload.php';

##Testing Update the $api variable to the API you want to run.

<?php

require_once __DIR__ . '/../vendor/autoload.php'; // Autoload files using Composer autoload

##Authentication First call the generate_token to get the access token After getting the access token, set it in the AccessToken index in the $configs to make other calls.

##Configurations The $configs parameters has the following indices

• AccessToken - The access token. Get the access to ken by running calling the `generate_token' API
• Environment - Can be sandbox (when testing your app) or live (when your app is in production)
• Content-Type - Should always be application/json
• Verbose - (Optional) for easy debugging, set this index to run your code in verbose mode ie echo and var dump parameters
• Url - (Optional), this overrides the endpoint. By default we use https://sandbox.safaricom.co.ke/ and https://api.safaricom.co.ke/ for sandbox and live respecitvely. Don't forget the forward slush as the end(/)

$configs = array(
    'AccessToken' => 'ACCESSTOKEN',
    'Environment' => 'sandbox',
    'Content-Type' => 'application/json',
    'Verbose' => 'true', //THIS
);

##Response The response has the following indices

• Environment - live or sandbox
• Name - The name of the API called
• HttpVerb - get or post
• HttpStatusCode - HTTP status code
• HttpStatusMessage - HTTP status message
• Message - Custom Message
• Response - Response array
• Endpoint - URL called
• Parameters - Parameters passed to the URL
• ExpectedResponse - Expected Reponse Parameters as documents in the API
