Frequently Asked Questions

What is the Open Integration Platform?

This is a program that provides the ability for third-parties (both vendors and customers) to build integrations into CCH Axcess products. This could include integration with common data as well as services specific to products, such as accessing files in CCH Axcess Document.

How will I benefit from becoming an Open Integration Platform partner?

You will benefit from integrations built into current (or future) applications you use along with CCH Axcess products. You also will have the ability to sign up as a partner and build your own integrations - either into third-party applications or into customer-built internal products that you use.

What value does the Open Integration Platform offer?

The Open Integration Platform extends Wolters Kluwer’s “Best in Process™” strategy to third-party applications by extending common data and common services to applications outside the CCH Axcess Suite. This results in greater efficiencies and productivity, as well as increases the overall ROI you will realize from Wolters Kluwer products.

What types of integrations are available?

Integrations are available for client and staff data, CCH Axcess Document linking and viewing, linking to projects in CCH Axcess™ Workstream, importing and exporting of CCH Axcess™ Tax return data, and silent login for unattended automation.
