Programmatically connect to Bitbucket/Bamboo from Jira for REST API use

Hi All,

As far as i saw, many people (include me) use REST API calls from Jira to GET/POST data from/to Bitbucket/Bamboo.

Most people are using hard coded credentials with Base64 Encode.

However, putting your credentials  hard coded (even in Base64 Encode format) is not the best practice, so i will share here a way that many users are not familiar with.

By using the following, you will be able to perform your REST API calls from Jira without putting credentials.

This will use the current login user credentials in Jira, to connect to Bitbucket/Bamboo

import com.atlassian.applinks.api.ApplicationLinkRequestFactory;
import com.atlassian.applinks.api.ApplicationLink;
import com.atlassian.applinks.api.ApplicationLinkService;
import com.atlassian.applinks.api.application.bamboo.BambooApplicationType;
import com.atlassian.applinks.api.application.bitbucket.BitbucketApplicationType;

In order to use this technique you will have to link Bitbucket/Bamboo to your Jira link applications.

And here is an example for how to use it:

/*to get the Bitbucket link*/
ApplicationLink getPrimaryBitbucketLinkLink() {
ApplicationLinkService applicationLinkService = ComponentLocator.getComponent(ApplicationLinkService.class);
final ApplicationLink bitbucketLink = applicationLinkService.getPrimaryApplicationLink(BitbucketApplicationType.class);

return bitbucketLink;

/*to get the Bamboo link*/
private ApplicationLink getPrimaryBambooLink() {
ApplicationLinkService applicationLinkService = ComponentLocator.getComponent(ApplicationLinkService.class);
final ApplicationLink bambooLink = applicationLinkService.getPrimaryApplicationLink(BambooApplicationType.class);

return bambooLink;

/*REST API GET request*/
private JSONObject getJsonData(ApplicationLink applicationLink, String restURL) throws Exception {
ApplicationLink appLink = applicationLink;
ApplicationLinkRequestFactory authenticatedRequestFactory = appLink.createAuthenticatedRequestFactory();

final Response[] res = new Response[1];

.createRequest(Request.MethodType.GET, restURL)
.addHeader("Content-Type", "application/json")
.execute(new ResponseHandler<Response>() {
public void handle(Response response) {
if (response.getStatusCode() != HttpURLConnection.HTTP_OK) {
try {
throw new Exception(response.getResponseBodyAsString());
} catch (Exception e) {
res[0] = response;

JSONObject jsonObject = new JSONObject(res[0].getResponseBodyAsString());

return jsonObject;

/*call the getJsonData function to get data from where we want*/
getJsonData(getPrimaryBitbucketLinkLink(), "/rest/api/latest/....")


Hope this will serve you well as it served me.

Feel free to reply my article and ask questions or share your thought with my methods.

Thanks for this - I'd been banging my head against the right way to make rest calls via the applinks for way too long today!

I was looking days till i figured it out.

That's why i felt like i have to post this article .

Glad it helped you :)

Hi Nir Haimov,

 Thank you for sharing this, if I can ask some more help, 

our requirement is to fill a JIRA custom field by accessing Bitbucket;  compare two tags in Bitbucket using REST API and get the JIRA issues used to commit between those tags. This fill may be required during a workflow transition.

So, how I can add your REST End point to a field behavior or to a Listener which will fill the JIRA custom field?

Thanks in advance

with warm regards



PS: in another use case I have one behavior to a single line text custom field like this

getFieldByName("Product 1 Branch").convertToSingleSelect([
ajaxOptions: [
url : getBaseUrl() + "/rest/scriptrunner/latest/custom/frnversions",
query: true,
formatResponse: "general"


which is accessing own JIRA dB and getting the projectversion based on user input. frnversions is the JIRA REST END Point for me in this case; I am looking for similar use case with Bitbucket access

Hi @Ramakrishnan S ,

As I understand you are using Scriptrunner,
I think it will be better and more simple if you use scripted field.

The method I mentioned in my article simply let you connect to Bitbucket/Bamboo without hard coded credentials, getting data with rest api and compare is pure code that need to be written.

Hi Nir Haimov,

 Thank you for the response, yes I am using script runner.

Let me try and give it a shot with your code as base


with warm regards
