communicating between an external configuration tool and JIRA.

[Sonal Singh]

Hi 

I need to find out how a system communicates with jira, to be more clear, how can i send notifications to jira (say to update an issue status) without using emails. I am not sure if i have explained my question thoroughly but i basically want to do task B in JIRA when a task A in another system is completed. 

what are the communication channels used in JIRA for incoming notifications? TIA

Have your external system call the api to make updates to the issue.  e.g. if wanting to transition the issue, call:

https://developer.atlassian.com/cloud/jira/platform/rest/v3/#api-rest-api-3-issue-issueIdOrKey-transitions-post

To search for issues to update, use:

For updating the status of an issue, look at workflow triggers.  For more general stuff (but also including status change), your external system will need to poke Jira over its REST API

Thanks Nic! I understand the status update using triggers in workflow transitions but that takes place inside JIRA, what if I want to update the issue using an external system, like my code is complete in system A and then I want to update the status of an issue to say ready for deployment. How do I achieved that? Can you elaborate more on REST APIs? Which API should be used in such case?
