```

## URI Request Parameters
<a name="API_GetLineageNode_RequestParameters"></a>

The request uses the following URI parameters.

 ** [domainIdentifier](#API_GetLineageNode_RequestSyntax) **   <a name="datazone-GetLineageNode-request-uri-domainIdentifier"></a>
The ID of the domain in which you want to get the data lineage node.  
Pattern: `dzd[-_][a-zA-Z0-9_-]{1,36}`   
Required: Yes

 ** [eventTimestamp](#API_GetLineageNode_RequestSyntax) **   <a name="datazone-GetLineageNode-request-uri-eventTimestamp"></a>
The event time stamp for which you want to get the data lineage node.

 ** [identifier](#API_GetLineageNode_RequestSyntax) **   <a name="datazone-GetLineageNode-request-uri-identifier"></a>
The ID of the data lineage node that you want to get.  
Both, a lineage node identifier generated by Amazon DataZone and a `sourceIdentifier` of the lineage node are supported. If `sourceIdentifier` is greater than 1800 characters, you can use lineage node identifier generated by Amazon DataZone to get the node details.
