I would like to link JIRA up to an existing system to pull data in automatically.
I can think of two ways of doing this:
1) We click on a link in our existing system which sends a JSON REST API request to a HTTP endpoint on JIRA which raises an Issue in JIRA Software and sets some fields based on the JSON values we provide.
2) We open an issue manually type in JIRA, key in a reference number, and click a button which makes a JSON REST API request to a HTTP endpoint hosted by our system, asking for some more details for that reference number and fills in other fields based on that call.
Are either of these possible? All documentation on JSON importing seems to suggest saving it to a local file and important it but that seems a little clunky - would much rather have a REST call lookup if possible.
Thanks,
Barry
