# Episodes_ListEpisodeRevisions

`GET /v1/accounts/{account}/datasets/{dataset}/episodes/{episode}/revisions`

An episode's edits, newest first, then the recording as revision 0; an
episode nobody edited lists nothing. The history is the take's: the same
through any dataset that holds it.

- Base URL: `https://junction-api.qualiastudios.dev`
- Authentication: an API key in the `X-API-Key` header

## Parameters

- `account` (path, string, required): The account id.
- `dataset` (path, string, required): The dataset id.
- `episode` (path, string, required): The episode id.
- `pageSize` (query, integer (int32)): At most this many; 0 means 50, the maximum is 500.
- `pageToken` (query, string): From a previous response's next_page_token.
- `revisions` (query, array of integer (int32)): Optional exact revisions (at most two, nonnegative). Cannot be combined
  with page_token. Missing revisions are omitted, never replaced by head.

## Responses

- `200` OK: `application/json` `qualia.v1.ListEpisodeRevisionsResponse`
- `default` Default error response: `application/json` `google.rpc.Status`

  description: |-
    One edit of a take's content, kept for good: what the history
    in the episode studio lists. A revision holds the whole state after the
    edit, not the change: a field the edit did not set holds the recording's
    value, as Episode reads it. What changed is its difference from the
    revision before it. Revision 0 is the recording itself, before any edit,
    so the first edit's changes read against it. Rulings (keep, reject) are
    not revisions.
