How to programatically check if a ticket is in a "closed" or "open" state?

[emanoel.moraes]

At the company I work we have many issue types and every issue type has different states, but all of the issue types have final states (closed). I would like to know if there is an endpoint that I can use to check if a ticket is in a closed or open state.

Get the issue with a call to

https://foobar.atlassian.net/rest/api/2/issue/FOO-123

and check the "statusCategory" embedded object:

"status": {
  "self": "https://foobar.atlassian.net/rest/api/2/status/10049",
  "description": "",
  "iconUrl": "https://foobar.atlassian.net/",
  "name": "Done",
  "id": "10049",
  "statusCategory": {
    "self": "https://midori-global.atlassian.net/rest/api/2/statuscategory/3",
    "id": 3,
    "key": "done",
    "colorName": "green",
    "name": "Done"
  }
  // ...

You will need to use Get issue endpoint.
