BookingEngine XML API Documentation

Introduction

Levart uses a subset of the Open Travel Alliance (OTA) XML specifications for the BookingEngine API. Levart has made use of the latest "2015B" version of the specifications for this implementation. The full OTA documentation including all schemas can be downloaded from http://www.opentravel.org/Specifications/Default.aspx

The OTA XML messages are implemented over the SOAP v1.2 protocol over a secure TLS1.2, HTTPS connection and are additionally protected with HTTP Basic authentication (via HTTP header). A username and password will be supplied to you for access in the introductory email from Levart.

Levart also provides a WSDL (Web Services Definition Language) file that describes the usage of the XML web services over SOAP including all XML schemas.

Generic Error Response (OTA_ErrorRS)

You may get an OTA_ErrorRS message in return instead of the expected OTA message if an error occurs early on in the parsing or authorization process.
