Call external REST API from workflow transition

I have in-house system which needed to be updated according to JIRA issue transit through workflows. 

I've tried below codes with scriptrunner post-function but having no luck. (getting stackoverflow error) 

If I cannot call the external REST services from JIRA, another way is to poll regularly from our in-house system. 

(or JIRA creates JSON file then process it via batch process?) 

Any help will be appreciated. 

import groovy.json.JsonSlurper;
import groovy.json.StreamingJsonBuilder;
import com.atlassian.jira.ComponentManager;
import com.atlassian.jira.issue.CustomFieldManager;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.IssueManager;
import com.atlassian.jira.component.ComponentAccessor;
import com.atlassian.jira.issue.Issue;
import org.apache.commons.codec.binary.Base64;

CustomFieldManager customFieldManager = ComponentAccessor.getCustomFieldManager();
def issue = issue as Issue
def issueStatus = issue.status;
// find custom fields
def cf2 = customFieldManager.getCustomFieldObjects(issue).find { == 'Original Call Log ID'};
def issueCalllog = issue.getCustomFieldValue(cf2);
def body_req = [
    "record.char_20": issueStatus,
    "record.char_21": issueCalllog
def baseURL = "http://rd0013:daniel12@";
URL url;
url = new URL(baseURL);
URLConnection connection = url.openConnection();
/*connection.requestMethod = "POST" */
connection.doOutput = true 
connection.setRequestProperty("Content-Type", "application/json;charset=UTF-8")
connection.outputStream.withWriter("UTF-8") { new StreamingJsonBuilder(it, body_req) }

Hi I would not recommend to go down this part. Look at setting up a JIRA webhook instead that send POST to your in-house system and do GET on what you need from JIRA when this occur.

Good luck!

thanks for advice.

trialled PoC on this approach and seems to be working.


Your welcome! Happy to share insights :smile:


Hi Niclas,

My task is like create Index on Elasticsearch whenever Ticket is created in Jira.

To create Index in Elasticsearch we need to pass some JSON which contains static JSON. but not related to JIRA ticket.

Is Weebhook pass JSON for me?

You can't get JIRA to send a custom JSON so this is not possible. You can track

You could see if any plugin enables this or just let middleware receive the push from JIRA and let that do what you need in Elasticsearch.

Good luck!

Thanks Niclas for quick reply

Hi Daniel,

I suppose you can try to use the Have a look at Jamie's asnswer

The above example makes a call to an external JIRA instance, but you can modify it. Hope that helps.
