|  Field  |  Type  |  Description  |
| --- | --- | --- |
|  id  |  String  |  The database ID of the pull request change. `Read-only`.  |
|  author  |  [User](api-entity-User.html)  |  The author of the pull request change. `Read-only`.  |
|  userNotFoundReason  |  Byte  |  The reason code that explains why the pull request change author could not be associated with a YouTrack user account. A value of `0` means that the author was resolved or no YouTrack user resolution reason was recorded.

|  hubUserNotFoundReason  |  Byte  |  The reason code that explains why the pull request change author could not be associated with a Hub user account. A value of `0` means that the author was resolved or no Hub user resolution reason was recorded. A non-zero value identifies the failed Hub-side lookup, such as no Hub user profile with a matching VCS username, more than one matching profile, or a matching user who is not available as an issue committer. `Read-only`.  |
|  fetched  |  Long  |  The date when the pull request change was fetched from the repository to YouTrack. `Read-only`.  |
|  state  |  [PullRequestState](api-entity-PullRequestState.html)  |  The pull request state after the change. `Read-only`. `Can be null`.  |
|  reopened  |  Boolean  |  True if the pull request was reopened by this change, otherwise false. `Read-only`.  |
|  pullRequest  |  [PullRequest](api-entity-PullRequest.html)  |  The pull request that contains the change. `Read-only`.  |
