Creating a child object (Record 'Alt in' Relationship)

The code

To add a new object to one of the child object collections on a TrimMainObject, for example adding a RecordRelationship to a Record, requires sending an array containing one or more objects to the appropriate collection. For Example, posting the code below to the Record endpoint will cause Record 9000000002 to be 'Alternately contained within' Record 9000008050.

{
    "Uri":9000000002, 
    "ChildRelationships":[
    {
        "RecordRelationshipRelatedRecord":9000008050,
        "RecordRelationshipRelationType": "IsAltIn"
    }]
}
