Nested dictionaries

Hello,

I am new at django and in over my head I think.  I am trying to create a kind of shim that will accept JSON from a webhook POST, work with the data using Python, and then POST some new JSON to another API.  I have successfully worked through tutorials that have "flat" data, and I have looked at the documentation on serializing nested data, but I don't see how to write the models to work with the serializers.  Does anyone know of a tutorial that demonstrates working with nested dictionaries?

Thank you,

Dave E.
