i am trying to develop add on for jira cloud,can i do it with technology other than node?
You can use any technology you want, as long as you can make REST API calls and build UI elements you are good to go. We are aware that most of our examples are in Node.JS but please don’t let that stop you.
I wrote a blog post about this a little while back: https://medium.com/@robertmassaioli/integrating-with-atlassian-connect-ea8912a58788
You might be interested in reading through that. It tells you how to make any web service an Atlassian Cloud App.
I would really love that. Could you give me some advice and resources so i could do that because i like to think i am good in php.
If you going to make a Cloud App with PHP first need this: https://github.com/firebase/php-jwt and with Zend Framework is easily to make REST API calls with HTTP client: https://framework.zend.com/manual/1.10/en/zend.http.client.html
