Version 4.2 Update – XML API Guide

We are pleased to announce update v4.2 of our Instant World Booking API Guide.  This new release includes some new features for updating allocations and rates.  Specifically:

  1. API Function: setallocation now includes the ability to update rates without altering # units, and vice versa.  This enhancement provides greater flexibility in the calendar management process.  See section 3.3 of the XML API Guide for a description of these new features.
  2. API Function: createrooms now automatically returns the room id assigned to a new room type.  This enhancement allows users to eliminate the extra step of submitting separate XML requests to obtain the room id for a new room type.  See section 3.1.2 for more details.
