How to Fetch Air Travel Data Using Sabre API in PHP

Initialize the Sabre API Client

• Ensure that you have the Sabre API SDK for PHP installed in your project. You can integrate it using Composer:

composer require sabre

• Construct the client and set up authentication. You'll need the credentials provided by Sabre:

use Sabre\Client;
use Sabre\Configuration;

// Create a configuration object
$config = new Configuration();
$config->setEnvironment(Configuration::ENVIRONMENT_PRODUCTION);
$config->setCredentials('your_client_id', 'your_client_secret');

// Initialize the Sabre client
$client = new Client($config);

Fetch Air Travel Data

• Define the parameters for your travel query, such as origin, destination, departure dates, etc.:

// Define flight search parameters
$params = [
    'origin' => 'JFK',
    'destination' => 'LAX',
    'departureDate' => '2023-12-25',
    'returnDate' => '2024-01-05',
    'limit' => 10,
    'currency' => 'USD'
];

• Use Sabre's flight search method. Handle potential exceptions to manage API limits and errors effectively:

try {
    $response = $client->get('/v1/offers/flights', $params);
    if ($response->isSuccess()) {
        $data = $response->getData();
        // Process the retrieved flight data
        foreach ($data['offers'] as $offer) {
            echo "Flight Id: " . $offer['id'] . "\n";
            // More data handling here
        }
    } else {
        echo "Error: " . $response->getStatus() . " - " . $response->getMessage();
    }
} catch (Exception $e) {
    echo "Exception: " . $e->getMessage();
}

Utilize the Parsed Data

• Format and display fetched data according to your application’s needs. Below is a basic example of printing flight offers:

// Example of processing the response data
foreach ($data['offers'] as $offer) {
    $price = $offer['price']['totalPrice']['amount'] ?? 'NA';
    $currency = $offer['price']['totalPrice']['currencyCode'] ?? 'USD';
    echo "Flight ID: " . $offer['id'] . "<br>";
    echo "Price: " . $price . " " . $currency . "<br>";
    echo "<hr>";
}

• Implement this output into your web page for better presentation and user interaction quality by using HTML templating or insertion directly into HTML elements with PHP.

Handle API Rate Limits and Errors

• Monitor the API usage to ensure compliance with Sabre's rate limitations. Utilize caching strategies and efficient retrieval techniques to avoid hitting these limits:

// Basic example of handling rate limits using sleep
try {
    // Make API call
} catch (RateLimitException $e) {
    echo "Rate limit hit. Sleeping for a few seconds.";
    sleep(5);
    // Retry the API call here
}

• Implement error logging and alerting mechanisms to detect and resolve issues in real-time:

if ($response->isError()) {
    error_log("API Error: " . $response->getErrorMessage());
}

Integrate the Data with Your Application’s Logic

• Finally, make sure to integrate the Sabre data with your application’s business logic. Example implementations include generating user interfaces or triggers based on the flight data.

// Sample integration with business logic
if ($data) {
    // Save data to database or cache
    saveFlightOffersToDB($data['offers']);
}

// Example function definition
function saveFlightOffersToDB($offers) {
    // Database logic to save offers
}

• This step enables further actions like user notifications or business rule enforcement related to the obtained travel data.
