This document will help ProQuest OASIS customers prepare their Alma system for use with the Real Time Acquisitions (or Ordering) API to allow communication between OASIS and the customer’s Alma system to insert purchase order lines as items are ordered in OASIS.
The setup process will involve configuration on both the Alma and OASIS systems.  Information will need to be obtained from the ExLibris developer’s website and information will need to be sent to ProQuest.
The API will create the order line in the Purchase Order as well as create a brief bibliographic record which may be used in the OPAC or discovery systems.  That record is very brief. We highly recommend that you be set up to do a nightly load of “brief” MARC records from ProQuest OASIS to overlay those records to provide better access.
ExLibris calls this process RTO or Real Time Acquisitions and has also has documentation at


The OASIS Real Time Acquisitions API is a web service that can be used to order any title in the OASIS catalog via a programmatic script. Note: a software developer with basic-to-intermediate skill level may be required to write the code to invoke the OASIS Real Time Acquisitions API.


All requests to the OASIS Real Time Acquisitions API require an API key. This key is unique per customer and should not be shared or distributed to anyone outside of your organization.
To obtain this key, the system administrator must contact OASIS customer service to request the OASIS Real Time Acquisitions API key:


The OASIS Real Time Acquisitions API requires the API key and a series of parameters as defined in your account setup at ProQuest.
The OASIS Real Time Acquisitions API is invoked via a REST call, whereby the parameters are defined as key-value pairs.

Required Parameters
