API to create constraints in assembly using mate connectors or published surfaces

Kin

Is there any API available to create constraints using mate connectors or geometry attached to the component being instantiated in the assembly?

You can do an "add feature" to this endpoint if you want to add a constraint to an assembly.

If you want a sample of what the feature definition should look like, the easiest way is to manually add one to your model, and then do a get request to this endpoint. The structure in the get features request is the same as it is to add the feature to the assembly.
