JIRA REST APIs are for developers who want to integrate JIRA with other standalone or web applications and administrators who want to script interactions with the JIRA server.
The Atlassian REST APIs provide a standard interface for interacting with JIRA and our other applications.
REST APIs provide access to resources (data entities) via URI paths. To use a REST API, your application will make an HTTP request and parse the response. Your methods will be the standard HTTP methods like GET, PUT, POST and DELETE. REST APIs operate over HTTP(s) making it easy to use with any programming language or framework.
The input and output format for the JIRA REST APIs is JSON.
JIRA uses the Atlassian REST plugin to implement the JIRA APIs. The REST plugin is bundled with JIRA. You can add your own REST APIs to JIRA by creating a JIRA plugin that includes the REST plugin module. See the basic principles we employ in our REST API design.
