How to get tickets from Jira using JavaScript

This tutorial is part of a series on building product integrations.

If you've ever worked on a software team, you've probably come across Jira, a project management tool that’s useful when it comes to tracking and streamlining tasks. It’s popular with teams that need to track bugs, issues, and manage agile projects. What’s great about Jira is its ability to work well with other digital tools; you can use the Jira API to access ticket data for analysis with other systems.

A common example we see at Merge is developers who want to pull tickets from a customer’s Jira system to automate ticket management or minimize manual labor. For the rest of this article, we’ll dig into how to do this by using the Jira API:

  • How to set up authentication
  • How to pull normalized data from Jira, specifically using fetch requests to pull tickets
  • The benefits of a single API endpoint to access third-party ticketing platforms

Setting up authentication

For authenticating with the Jira API, you'll need to include an HTTP header in your requests. This header should be in the format `Authorization: {Email Address}:{API-KEY}`. Here, `{Email Address}` is your Jira account email and `{API-KEY}` is the API key generated from your Jira account. Both of these values should be base64-encoded.

This is how you can generate the base64-encoded string of your email and API key in JavaScript:


var email = 'your-email@example.com';
var token = 'your-api-token';
var buff = new Buffer(email + ':' + token);
var base64data = buff.toString('base64');
console.log('Encoded Token: ' + base64data);

The resulting string will be used in the `Authorization` header of your requests. You’ll first need to install the `node-fetch` and `btoa` libraries using the command `npm install node-fetch btoa` in your terminal or command line interface.


const fetch = require("node-fetch");
const btoa = require("btoa");

Next, create a function that will get the tickets from Jira. The function will take in three arguments: `email`, `apiKey`, and `domain`.


async function fetchTickets(email, apiKey, domain) {
  const base64auth = btoa(`${email}:${apiKey}`);
  const headers = {
    "Authorization": `Basic ${base64auth}`
  };

  let startAt = 0;
  let maxResults = 50;
  let tickets = [];

  while (true) {
    const response = await fetch(`https://${domain}.atlassian.net/rest/api/3/search?expand=renderedFields&startAt=${startAt}&maxResults=${maxResults}`, { headers });
    const data = await response.json();

    tickets = tickets.concat(data.issues);

    if (!data.issues.length) {
      break;
    }

    startAt += maxResults;
  }

  return tickets;
}

To use this function, you can call it in your application and pass in your email, API key, and domain associated with your Jira account.


fetchTickets('YOUR-EMAIL', 'YOUR-API-KEY', 'YOUR-DOMAIN')
  .then(tickets => console.log(tickets))
  .catch(err => console.log(err));

This function will continuously pull data from the Jira API until there are no more tickets to retrieve. Tickets are returned as an array of JSON objects. Below is an example of an individual item returned by this API Endpoint:
