Travel API Integration in PHP XML JSON Hotels Flights Payments

Travel API Essentials

A travel API exposes search, pricing, booking and post-booking operations for inventory such as hotels, flights, cars, activities and packages. Responses are typically XML or JSON with auth via keys, OAuth or supplier tokens. See also What is API Integration?

check_circle Operations: Search • Price/Revalidate • Book • Issue/Ticket • Cancel/Refund
check_circle Data: rooms/fares rules, availability, rate plans, ancillaries, policies
check_circle Transport: XML/JSON, pagination, caching, idempotent booking

Travel API integration module in PHP (XML/JSON)

Travel API integration in PHP

Fast answer: Use JSON where possible; fall back to XML/XSD for GDS/bedbanks. Implement search → price/revalidate → book → issue/refund with idempotency on “book”.
What you get: Hotel & Flight API integration, live rates/availability, commissions/markups, payments for agencies & OTAs (VCCs, 3-DS), logs, retries.
Time to go-live: 2–4 weeks per supplier incl. sandbox, certification, production cutover.

Travel API Hub

One place to connect GDS, bedbanks, tours, cars and payments with unified flows (search→price→book→issue/refund) and shared logging, retries and observability.

Travel API Integration in PHP (JSON)

<?php
$payload = [
  "origin" => "LHE", "destination" => "DXB",
  "departDate" => "2025-11-15", "adults" => 1
];
$ch = curl_init("https://sandbox.example.com/api/v1/air/search");
curl_setopt_array($ch, [
  CURLOPT_POST => true,
  CURLOPT_HTTPHEADER => ["Content-Type: application/json","Authorization: Bearer YOUR_TOKEN"],
  CURLOPT_POSTFIELDS => json_encode($payload),
  CURLOPT_RETURNTRANSFER => true, CURLOPT_TIMEOUT => 30,
]);
$res = curl_exec($ch);
if (curl_errno($ch)) throw new Exception(curl_error($ch));
$data = json_decode($res, true); // handle results
?>

Best practices: retries with exponential backoff, request IDs for tracing, idempotency keys on “book”, circuit breakers for supplier downtime.

Hotel Search (XML pattern)

<SearchRequest>
  <Destination>DXB</Destination>
  <CheckIn>2025-11-15</CheckIn>
  <Nights>3</Nights>
  <Rooms><Room adults="2" children="0"/></Rooms>
</SearchRequest>

Use supplier-specific XSDs; normalize room types, rate plans and cancellation rules before caching.

XML vs JSON for Travel APIs

XML

Legacy GDS/bedbanks, strict XSDs, verbose payloads, strong schemas, good for complex fare rules.

Amadeus Travelport Sabre

JSON

Modern REST, smaller payloads, faster to parse, easier in JS/PHP. Prefer JSON where suppliers provide parity.

How to automate payment APIs in travel agencies

Choose gateway strategy: VCCs for suppliers, cards with 3-DS for B2C, payouts/wallets for B2B.
Implement auth & webhooks (payment_intent, capture, refund, dispute) with retries/backoff.
Map PNR/booking IDs to payment IDs for reconciliation; generate vouchers after capture.
Automate refunds and partial captures per fare/cancellation rules.
Minimize PCI scope (tokenization, hosted fields) and enable risk tools.
