CreateNode with belongTo

• Params like create basicNode & versionedData but in objectSchema optional has belongTo If in objectSchema have belongTo will create query and return dataStructure of belongTo
• Must send : x-correlation-base-user-id : xxxx AND x-correlation-target-id : yyyy ( identifiers of that node)

CreateNode with extendObjtype

• create objectSchema that have objectType for create main node eg. objectType: objectA then upload To S3
• create objectSchemathat have extendObjtype for existParentNode eg. objectType: objectB then upload To S3
• Send parameter with identifiers’s objectType of extendObjtype for create Node

CreateNode with extendObjtype and targetNode

• create objectSchema that have objectType for create main node eg. objectType: objectA
• createNode extend with relationship that have relationshipSchema : requiredOnCreate = true to targetNode

CreateNode With systemGenerated

• not send userNode or userId when createNode
