Way back in October 2010 we released JIRA 4.2 and the first real REST API for JIRA. We continued to add to it over 4.3 and 4.4. By February 2012 we felt confident in the direction our REST API was going and removed the alpha and beta labels from it in JIRA 5.0. The scope of the API continued to expand over subsequent releases: 5.1, 5.2, and now 6.0. With the continued growth of our REST APIs we've made the decision to officially deprecate the SOAP and XML-RPC remote APIs.
Deprecating SOAP and XML-RPC means that developers have a clear and consistent message from us about how they should be interacting with JIRA remotely. They won't build up code relying on SOAP and then be disappointed when new features don't get added or bugs don't get fixed. No false hope and no bullshit: REST is the future.
Of course, we know that there is a lot of existing code out there so we're not going to take out SOAP behind the woodshed and shoot it immediately.
SOAP and XML-RPC will continue to work without change during the JIRA 6.x lifecycle, however we won't be spending any more effort on bugfixing or feature requests. When JIRA 7.0 is released the code will be removed from JIRA and they will become unsupported by Atlassian.
- The remote APIs provided by the rpc-jira-plugin. The full list can be found here: http://docs.atlassian.com/rpc-jira-plugin/latest/. The JiraSoapService and JiraXmlRpcService are the most commonly used interfaces from the deprecated plugin.
- The rpc-soap and rpc-xmlrpc plugin module descriptors. These module descriptors can be used by plugins to provide custom SOAP and XML-RPC endpoints. If you want to extend JIRA with custom remote APIs you should use the REST Plugin Module Type.
Right now the JIRA REST API has pretty good coverage of the SOAP API but it isn't 100% complete. Atlassian is absolutely committed to making every feature of the SOAP API available in the REST API. Making that happen is a precondition of removing the SOAP and XML-RPC APIs from JIRA. We will be working toward that goal during the 6.x and 7.0 development cycles.
