Instances and System Parameters API

Description of API:

Thomson Reuters ONESOURCE Tax Provision APIs provide provision calculations across multiple dimensions, to enable you to do extensive analysis of your data, while improving efficiencies throughout the tax provision process.

ONESOURCE Instances and System Parameters API is a REST web service that returns the instances you have access to and the active system parameters for each instance. This will allow you enhanced transparency on the instances you have access to, use them for other APIs, and see the system parameters present on each one of them.

The Instances API allows ONESOURCE Tax Provision users to retrieve a list of all instances that are available to them. The users will see the ID and name of the instances. The list can be filtered and sorted. The number of records returned per query can be limited (maximum 100) and the index of the first record can be modified so the users can see more than the first 100 instances.
