How to query the linked Confluence space of a Jira Cloud project using the REST API?

[Peter Velosy]

Dear Community,

After linking a Jira Cloud project with a Confluence space (Project pages -> Connect), how can I query the key/id of the associated Confluence space using the Jira (or Confluence) REST API?

Many thanks!

There isn't a way to get this from the REST API that I am aware of but you can get it through the Atlassian GraphQL gateway with a couple of queries:

      query GetAllJiraProjects(
        $cloudId: ID!, 
        $first: Int, 
        $after: String
      ) {
        jira {
          allJiraProjects(
            cloudId: $cloudId,
            filter: {}, 
            first: $first, 
            after: $after
          ) {
            edges {
              node {
                id
                name
              }
            }
            pageInfo {
              hasNextPage
              endCursor
            }
          }
        }
      }

      query GetConnectedConfluenceSpaces($projectARI: ID!) {
        devOps {
          ariGraph {
            relationships(
              filter: {from: $projectARI, type: "project-documentation-entity"}
              sort: {lastUpdatedSortDirection: DESC}
            ) {
              nodes {
                to {
                  id
                  data {
                    ... on ConfluenceSpace {
                      id
                      name
                    }
                  }
                }
              }
            }
          }
        }
      }

Variables:

• $cloudId - A UUID-like string used in Atlassian Cloud (i.e. xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)
• $projectARI - starts with "ari:cloud:jira::", followed by "project/" (i.e. ari:cloud:jira:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx:project/xxxxx)
• $first - how many records to return
• $after - starting position used for pagination (put endcursor here)

Hi @Peter Velosy  my name is Habib I shall do my best to help you with the question.

To query the key/id of the associated Confluence space using the Jira or Confluence REST API, follow these steps:

1. First, obtain the Jira Cloud project key and the Confluence Cloud space key.

2. Make a GET request to the Jira REST API endpoint that returns information about the project. The endpoint is in the following format:
```
https://your-domain.atlassian.net/rest/api/2/project/{projectKey}
```
Replace `{projectKey}` with the actual key of your Jira Cloud project.

3. In the response, look for a field called `projectCategory`. This field contains a nested object with a `projectCategoryKey` field. The value of `projectCategoryKey` is the key of the Confluence Cloud space associated with the Jira Cloud project.

4. Make a GET request to the Confluence REST API endpoint that returns information about the space. The endpoint is in the following format:
```
https://your-domain.atlassian.net/wiki/rest/api/space/{spaceKey}
```
Replace `{spaceKey}` with the actual key of your Confluence Cloud space.

5. In the response, look for a field called `key`. The value of `key` is the key of the Confluence Cloud space associated with the Jira Cloud project.

Alternatively, you can also use the Jira REST API to get the Confluence space key by making a GET request to the following endpoint:
```
https://your-domain.atlassian.net/rest/jira/latest/project/{projectKey}/properties/confluenceHome
```
Replace `{projectKey}` with the actual key of your Jira Cloud project.

The response will contain a `value` field, which is a URL that points to the Confluence Cloud space homepage. The space key is the last part of the URL, after the `/display/` path.

I hope this helps. 
thank you

The Project Category is a different entity than the Confluence space associated with the Jira project. Maybe in your case, the two ID-s accidentally match up, but this is not the case on my end.

By the way, I have a strong suspect that you (provided that you are a human at all) generated this response with ChatGPT. Please refrain from spamming this expert forum this way. If you are a human who uses ChatGPT for researching information, please double-check if the response is correct and if it makes sense, as it is often not the case with language models.
