Learn how to make the REST API requests to Jira Server and Data Center using basic authentication with a username and password. If you’re looking for information about Jira Cloud basic authentication, check out the deprecation notice.
Jira’s REST API is protected by the same restrictions that are provided via Jira’s standard web interface. This means that if you do not log in, you are accessing Jira anonymously. Furthermore, if you log in and do not have permission to view something in Jira, you will not be able to view it using the Jira REST API either.
Basic authentication provides a simple mechanism to do authentication when experimenting with the REST API, writing a personal script, or for use by a bot. However, as basic authentication repeatedly sends the username and password on each request, which could be cached in the web browser, it is not the most secure method of authentication we support.
We recommend you use OAuth over basic authentication for most cases. OAuth requires more work to implement, but it uses a token-based workflow that is much more secure.
To send a request using basic authentication, you'll need the following:
We will use the cURL command in Terminal or Command Prompt, but any other tool to send requests can be used. Note, if you are using a version of Windows prior to Windows 10 you will need to install cURL.
Most client software for sending requests automatically generate the authorization header when you provide a username and password.
For example, in cURL you can specify a username and password combination with the argument to send a request to a Jira site as follows:
curl -u username:password -X GET -H "Content-Type: application/json" http://localhost:8080/rest/api/2/issue/createmeta
If you need, you can construct and send the basic authorization header yourself as follows:
For example, if your username and password are both fred then the string "fred:fred" encodes to ZnJlZDpmcmVk in Base64. You can then make a request with cURL specifying the authorization header with as follows:
curl -H "Authorization: Basic ZnJlZDpmcmVk" -X GET -H "Content-Type: application/json" http://localhost:8080/rest/api/2/issue/createmeta
Once you’re comfortable making simple requests, there are a couple of topics you may need to consider further for your use-case.
Because Jira permits a default level of access to anonymous users, it does not supply a typical authentication challenge.
Some HTTP client software expect to receive an authentication challenge before they send an authorization header. This means that the software may not behave as expected. In this case, you may need to configure the software to supply the authorization header, as described above, rather than rely on its default mechanism.
CAPTCHA is a tool that can distinguish a human being from an automated agent such as a web spider or robot. CAPTCHA is triggered after several consecutive failed login attempts, after which the user is required to interpret a distorted picture of a word and type that word into a text field with each subsequent login attempt. If CAPTCHA has been triggered, you cannot use Jira's REST API to authenticate with the Jira site.
If CAPTCHA was triggered you will receive an error response from Jira when making requests through the REST API. You can determine if CAPTCHA is causing the error by checking if there is an header with a value of in the response. If present, this means the application rejected the login without even checking the password. While this is the most common indication that Jira's CATPCHA feature has been triggered, you can also check the number of failed login attempts for the bot-user in Jira's user administration.
