====== Teamamerica Delta API Documentation ======


Welcome to the Teamamerica Delta API Interface Guide. 
We hope you will have a smooth and successful integration to our system.


==== Overview ====

This Delta API significantly reduces the need for clients to perform millions of searches daily and enables efficient synchronization by ensuring the client maintains the up-to-date hotel inventory data. This API provides a list of changes that have been created, updated, or deleted within a specified time frame. The response is available in XML and JSON formats and serves two key purposes:

  - **Cache Updates:** The API returns date ranges that require cache updates on the client side, which should be refreshed using the **XML5+ PriceSearch** API.
  - **Inventory Updates:** The API provides availability statuses within specific date ranges, indicating which dates went on **OnRequest** or **ClosedOut**.

**Pre-requirement: To use this API, you must first cache the full TA portfolio through XML5+.**

Development Rest EndPoint: http://devxml40.volateam.com:8081/TaDeltaApi/TeamAmerica/

**Note:** **Only whitelisted IP addresses will be granted access to this endpoint**. Please ensure that the relevant IP addresses are whitelisted to avoid any disruption in service.
