# SourceRevisionOverride
<a name="API_SourceRevisionOverride"></a>

A list that allows you to specify, or override, the source revision for a pipeline execution that's being started. A source revision is the version with all the changes to your application code, or source artifact, for the pipeline execution.

**Note**  
For the `S3_OBJECT_VERSION_ID` and `S3_OBJECT_KEY` types of source revisions, either of the types can be used independently, or they can be used together to override the source with a specific ObjectKey and VersionID.
