Zephyr for Jira Server exposes its data via a REST API which allows you to access the data programmatically and build your own integrations. The API is entirely HTTP-based. You can use the API to:

  • Integrate with test automation tools.

  • Integrate with continuous integration tools.

  • Create extensive custom reports for testing.

  • Integrate with business intelligence tools.

  • Use the testing data for other purposes.

For example, you can build an integration that would create a test in a separate tool or system and add it to Zephyr for Jira Server or create a test execution cycle and update the status of a test execution run after it has been executed in an automation tool.

Previously, to access Zephyr for Jira Server REST API, you had to install an additional plugin (ZAPI). As of October 2020, the API is available out-of-the-box, and the ZAPI plugin is no longer needed.


Follow the link below to view the API documentation along with code examples for cURL, C#, JavaScript, Node.js, Python, PHP, and Ruby.

Using the API, you can:

  • Get information about users, projects, releases, tests and execution cycles.

  • Create new tests and test execution cycles.

  • Update tests and test execution status.

  • Add attachments to existing execution cycles.

  • Run ZQL queries and retrieve search results.

Base URL

The base URL for API calls is:


For example, POST /jira/rest/zapi/latest/cycle means a POST request to http://localhost:2990/jira/rest/zapi/latest/cycle, which creates a new cycle.

JSON requests

Most operations that accept a request body expect it in the JSON format.

POST and PUT request containing a JSON request body must include the Content-Type header:

Content-Type: application/json

Rate limits

  • 1,000 requests per hour.

  • 24,000 requests per day.


  • There are pagination limits.

  • Encoding affects status character counts.
