Updating the link of issues using JIRA API

Hey mates,

I am trying to add/update the link in issue using JIRA API. But i am getting Bad request (error 400)


JSON code:

"update": {
"issuelinks": [{
"type": {
"name": "Relates"
"inwardIssue": {
"key": "XPTO-29432"
"OutwardIssue": {
"key": "XPTO-29072"


URI: https://XPTO.jira.com/rest/api/2/issueLink 


Code i am using to PUT

HttpPut put = new HttpPut(uri);
put.setHeader("Content-Type", "application/json");
put.setHeader("Authorization", "Basic " + args.getJiraAuthToken());
HttpEntity entity = new ByteArrayEntity(json.getBytes("UTF-8"));
HttpResponse response = httpClient.execute(put);


my json object is the one i tell u in this text.


Do you have any idea what is going on? I already try with POST but still not working.

You can install on your Jira instance Rest Api Browser Addon  and check if your json is correct. If your Json is not correct Jira will return you a message about the error.

Or you can add to your code something like this to see the exact message of the error:

 BufferedReader br = new BufferedReader(
new InputStreamReader((response.getEntity().getContent())));

String output;
while ((output = br.readLine()) != null) {


Thank you :)
I am getting this message erro:

Code: 400

{"errorMessages":[],"errors":{"issuelinks":"Field 'issuelinks' cannot be set. It is not on the appropriate screen, or unknown."}}

i change my uri to: https://xpto.jira.com/rest/api/2/issue/XPTOISSUE-29432

You need to use a different REST API for linking issues. You can read about it here:


Thank you :) its working.
