From an integration perspective, CDQ web services are the most important component of the CDQ infrastructure. They provide the technical link between your business applications and the CDQ cloud services. We follow the REST design principle for web services which allows for lightweight interface design and easy integration. Of course, all web services are also available at WSDL interfaces.
The end-of-life of the CDL API (Legacy) is planned for March 2021. As of this date, no access nor support of any kind will be available for this API.
