I have a few questions about contentId

Damon Williams

I am looking to use Confluence to store some content strings for another applicaiton, which will pull in the strings via the getContentById REST API.

What is assigned a contentId?  Can it be something smaller than a page?  Could I have a series of 10 strings on a page that each had a distinct contentId, such as if I put each one is a different macro?  Finally, how do I find the contentId for a piece of content?

Is this Confluence SERVER or Confluence CLOUD?

What is assigned a contentId

Any valid contentType. Out of the box, this includes Pages, Blog Posts, Comments, and Attachments.

Can it be something smaller than a page?

Well... Comments and Attachments I guess? 

Could I have a series of 10 strings on a page that each had a distinct contentId, such as if I put each one is a different macro?

Macros are not considered "contentTypes" so no, this is not supported out-of-the-box.

Finally, how do I find the contentId for a piece of content?

Use the API:

• The JAVA API includes the PageManager with getPageWithComments(String spaceKey, String pageTitle) method. This will return a Page object with a getContentId() method.
• The REST API includes a /content/ endpoint that allows you to specify a Space and a Page via Path Parameters: 

  /confluence/rest/api/content?title=myPage%20Title
  &spaceKey=TST

If you want to, you could extend ContentTypes in both Cloud or Server to add more flexibility for your use-case.
