Engineering Lifecycle Management API Landing page constantchange.png"

Authors: RosaNaranjo, JimRuehlin, MichaelRowe
Build basis: 7.0.x


This is a landing page for the various API wiki pages that exist on Jazz.net as well as a central collective page of the known APIs that are available for integrating programmatically with our Engineering Lifecycle Management (ELM) products. It serves as a convenience for accessing API information about ELM products and is not guaranteed to have up-to-the-minute information. See the official API specifications for each ELM component for complete information.
Please see the IBM Support Statement for ELM APIs. APIs are supported differently than ELM products.
IBM strongly advises that any scripts that customers develop using APIs be tested in a staging environment prior to use in a production environment. Scripts can have unintended performance or other consequences and thus should be highly scrutinized prior to deployment on production systems. See API Automation Best Practices

General OSLC and ELM API information

Note all ELM servers have some level of API documentation located at

Global Configuration Management

GCM is a provider of global configurations as defined by the OSLC Configuration Management specification; EWM SCM, DOORS Next, and ETM are providers of local configurations. These applications implement the appropriate APIs from that specification.

Documentation for the Global Configuration Management REST API can be found at https://[server]:[port]/gc/doc/scenarios. You must have the GC application installed to access this link.

Engineering Requirements Management DOORS Next (DN)

This API is a collection of REST services that client applications use to create and update components, create new streams, create baselines, update a stream to match a baseline, and other operations. REST client applications can use the API to programmatically perform many of the operations that are usually done through the GCM web user interface.

Plain Java Client or Jazz APIs

The "official" Jazz API is available for download on the downloads page, in the Plain Zips section, under Plain Java Client Libraries and Plain Java Client Libraries API Documentation. The article Rational Team Concert plain Java API's is an introduction into how they work. Customers wishing to write process extensions for their Jazz implementation should begin with the RTC extensions workshop, the Process enactment workshop, and the OSLC workshop. This will help them better understand the various different options for extending and enhancing the Jazz solution, and will provide valuable insight into how to implement the needed customizations.
