# About the Comment Content Revisions API

The Comment Content Revisions API retrieves earlier versions of a comment's rich
content.

With the Comment Content Revisions API, you can:

- List the saved earlier content versions of a comment.
- Build an edit-history view alongside the comment's current content.

A revision is a saved earlier content version, not the current comment object or
its optimistic-concurrency `revision` number. Read the current content using the
[Comments API](https://dev.wix.com/docs/api-reference/crm/community/feedback-moderation/comments/comments/introduction.md). The history response can contain no revisions for a comment that
has not yet produced a saved earlier version.

## Before you begin

It's important to note the following points before starting to code:

- Provide the comment ID and authentication for its site. Each request checks access to the current comment, including requests for subsequent pages. A denied or missing comment fails the request.
- History can contain content that differs from the current comment. Updates are asynchronous, so a recent edit might not appear immediately.
- Deleting a comment triggers deletion of its history. Don't use this API as a permanent audit archive or draft store.

## Pagination and sorting

List Comment Content Revisions defaults to 20 entries, sorted by history record creation time
ascending. `createdDate` is the supported sorting field. Use the cursor in
`pagingMetadata.cursors.next` to load subsequent pages. Omit `sort` on subsequent
pages: the cursor retains the original ordering, but a supplied unsupported sort
field still fails validation.

The returned `createdDate` uses the saved content's date when available, falling
back to the history record's creation date. It is not necessarily the time the
history service stored the entry.

## Use cases
