TABLE OF CONTENTS

Introduction

Regarding the GO Distributor Push Model, there are two modes: Delta and Overlay.

  • Delta - It's an incremental update for the changed products and it supports up to 15 products per request. If the number of changed products exceeds 15, multiple push requests will be sent.
  • Overlay - All products undergo a full update whenever any product has an ARI change. 

How to identify the Push Mode

You can identify the push mode through the MessageType field in the request of AvailabilityPeer - ARI Push API. Below is an example for Delta mode, please notice that If the field is omitted in the request it means the message type is Overlay.

How it works

Refer to the sample below for clarification: There are a total of 4 products available for hotel GOH101, which are combined by roomId and rateId.

Overlay mode will push a full update for ALL products in one request for the hotel.
