Interface

You might like to use an interface to manage your API session, package your requests, and include authentication credentials.

In the example below, we use Pest, available at

https://github.com/educoder/pest

Here’s an code snippet that gets and displays FLAPI data (from the developer sandbox) in PHP

// Load the library (Pest folder must be in PHP's include path)
require_once 'Pest/PestJSON.php';
include '../data/flapi_credentials.php'; // e.g. contains: $flapi = [ ‘user’, ‘pass’ ];

// Init the library (put in your TC credentials here)
$apiClient = new PestJSON( 'https://dev.flyerlink.com/api.php' ); 
//  $apiClient->setupAuth( 'username', 'password' );
$apiClient->setupAuth($flapi[0],$flapi[1]);

// Make a simple get call (this returns tag types in JSON format)
try {
    $result = $apiClient->get('/product_categories/?format=json');
}
catch (Exception $e) {
    // Handle error. In practice there are several exception types,
    // which you can use to differentiate between different error conditions
    die( $e->getMessage() );
}

// Examine successful result
// This just outputs to the page; you'll want to present it nicely.
echo '<pre>';
print_r( $result );
echo '</pre>';
