this is my code for links:

  this.diagram.linkTemplate = $(
      go.Link,
      {
      
        reshapable: this.allowEdit,
        resegmentable: this.allowEdit,
        relinkableFrom: this.allowEdit,
        relinkableTo: this.allowEdit,
        fromSpot: go.Spot.AllSides,
      },
      $(go.Shape),
      $(go.Shape, { toArrow: 'Standard' })
    );

Add this Binding to your link template:

    new go.Binding("points").makeTwoWay()

Are you using the Model.toJson method and Model.fromJson static function to serialize your model? If so, it should just work.

If not, then you’ll have to save the Link.points List of Points yourself somehow, and then restore them in an “InitialLayoutCompleted” DiagramEvent listener.
