Use JIRA webhook data in Google Script Project - json

Question

I am trying to get the following to work: A JSON is sent to my Google Script - Now I want to get specific values from that JSON Message and store them into specific rows of one specific Google Spreadsheet. So far so good, this is what I have :
function doPost(response) {
var sheets = SpreadsheetApp.openById('MY SHEET ID');
var dataAll = JSON.parse(response.getContentText());
var nR = getNextRow(sheets) + 1;
// RECORD DATA IN SPREADSHEET
sheets.getRangeByName('timestamp').getCell(nR,1).setValue(new Date());
sheets.getRangeByName('ticket_id').getCell(nR,1).setValue(dataAll);
}
function getNextRow(sheets) {
var timestamps = sheets.getRangeByName("timestamp").getValues();
for (i in timestamps) {
if(timestamps[i][0] == "") {
return Number(i);
break;
}}}
It should store the response and put it into a blank cell of the range "timestamp". But nothing happens at this point.
This is the JSON ( Body ) from JIRA:
{"timestamp":1483576902984,"webhookEvent":"jira:issue_created","issue_event_type_name":"issue_created","user":{"self":"https://xxx.atlassian.net/rest/api/2/user?username=admin","name":"admin","key":"admin","emailAddress":"test#mail.at","avatarUrls":{"48x48":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=48","24x24":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=24","16x16":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=16","32x32":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=32"},"displayName":"Max Mustermann [Administrator]","active":true,"timeZone":"Europe/Berlin"},"issue":{"id":"10057","self":"https://xxx.atlassian.net/rest/api/2/issue/10057","key":"TA-58","fields":{"issuetype":{"self":"https://xxx.atlassian.net/rest/api/2/issuetype/10104","id":"10104","description":"A problem which impairs or prevents the functions of the product.","iconUrl":"https://xxx.atlassian.net/secure/viewavatar?size=xsmall&avatarId=10303&avatarType=issuetype","name":"Bug","subtask":false,"avatarId":10303},"timespent":null,"project":{"self":"https://xxx.atlassian.net/rest/api/2/project/10000","id":"10000","key":"TA","name":"Test Area","avatarUrls":{"48x48":"https://xxx.atlassian.net/secure/projectavatar?avatarId=10324","24x24":"https://xxx.atlassian.net/secure/projectavatar?size=small&avatarId=10324","16x16":"https://xxx.atlassian.net/secure/projectavatar?size=xsmall&avatarId=10324","32x32":"https://xxx.atlassian.net/secure/projectavatar?size=medium&avatarId=10324"}},"customfield_10110":null,"fixVersions":[],"customfield_10111":null,"aggregatetimespent":null,"customfield_10112":"Not started","resolution":null,"customfield_10113":null,"customfield_10114":null,"customfield_10104":null,"customfield_10105":null,"customfield_10106":null,"customfield_10107":null,"customfield_10108":null,"customfield_10109":null,"resolutiondate":null,"workratio":-1,"lastViewed":null,"watches":{"self":"https://xxx.atlassian.net/rest/api/2/issue/TA-58/watchers","watchCount":0,"isWatching":false},"created":"2017-01-05T01:41:42.903+0100","priority":{"self":"https://xxx.atlassian.net/rest/api/2/priority/3","iconUrl":"https://xxx.atlassian.net/images/icons/priorities/medium.svg","name":"Medium","id":"3"},"customfield_10100":null,"customfield_10101":null,"customfield_10102":null,"customfield_10103":null,"labels":[],"timeestimate":null,"aggregatetimeoriginalestimate":null,"versions":[],"issuelinks":[],"assignee":null,"updated":"2017-01-05T01:41:42.903+0100","status":{"self":"https://xxx.atlassian.net/rest/api/2/status/10000","description":"","iconUrl":"https://xxx.atlassian.net/","name":"To Do","id":"10000","statusCategory":{"self":"https://xxx.atlassian.net/rest/api/2/statuscategory/2","id":2,"key":"new","colorName":"blue-gray","name":"To Do"}},"components":[],"timeoriginalestimate":null,"description":"super alles neu","timetracking":{},"customfield_10005":null,"attachment":[],"aggregatetimeestimate":null,"summary":"super alles neu","creator":{"self":"https://xxx.atlassian.net/rest/api/2/user?username=admin","name":"admin","key":"admin","emailAddress":"test#mail.at","avatarUrls":{"48x48":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=48","24x24":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=24","16x16":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=16","32x32":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=32"},"displayName":"Max Mustermann [Administrator]","active":true,"timeZone":"Europe/Berlin"},"subtasks":[],"reporter":{"self":"https://xxx.atlassian.net/rest/api/2/user?username=admin","name":"admin","key":"admin","emailAddress":"test#mail.at","avatarUrls":{"48x48":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=48","24x24":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=24","16x16":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=16","32x32":"https://secure.gravatar.com/avatar/3d238d8be45bd26982fa09ae2f891c3f?d=mm&s=32"},"displayName":"Max Mustermann [Administrator]","active":true,"timeZone":"Europe/Berlin"},"customfield_10000":"{}","aggregateprogress":{"progress":0,"total":0},"customfield_10001":null,"customfield_10115":null,"customfield_10116":"0|i0005r:","environment":null,"duedate":null,"progress":{"progress":0,"total":0},"comment":{"comments":[],"maxResults":0,"total":0,"startAt":0},"votes":{"self":"https://xxx.atlassian.net/rest/api/2/issue/TA-58/votes","votes":0,"hasVoted":false},"worklog":{"startAt":0,"maxResults":20,"total":0,"worklogs":[]}}}}
However, I don't want to have the whole JSON in my cell, I only want to have specific obejcts/id from within the JSON. How do I call them ?

Answer 1

After tons of research, this is a solution that works for me (in my case):
function doPost(response) {
var sheets = SpreadsheetApp.openById('SHEET_ID');
// retrieve data from JIRA Payload and store them into "data"
var json = response.postData.contents;
var data = JSON.parse(json);
// index values from "data" and store them into seperate variables
// for example:
var ticket_id = data.issue.key;
var priority_name = data.issue.fields.priority.name;
var summary = data.issue.fields.summary;
This two lines:
var json = response.postData.contents;
var data = JSON.parse(json);
Made it possible to read the body and index all the specific parameters I want.

Answer 2

Here is an example:
/*
* webhookHandler: JIRA webhook callback function
*/
function webhookHandler(response) {
var data = response.getAs("application/json");
//logs out data in dev console
console.log(data);
var spreadsheet = SpreadsheetApp.openById("<spreadsheet id>");
var cellRange = spreadsheet.getRangeByName("<some range name>");
var cell = cellRange.getCell(0 /*row index*/, 0/*column index*/);
cell.setValue(data.ticket_id/*index the JSON object returned by response*/);
}
