If you create a class that extends flask.ext.admin.contrib.sqla.ModelView, you can override the on_model_change method.

See http://flask-admin.readthedocs.org/en/latest/api/mod_model/#flask.ext.admin.model.BaseModelView.on_model_change

For example, something like this:

from flask.ext.admin.contrib.sqla import ModelView

from my_app import app, db
from models import MyModel


class MyModelView(ModelView):
    ...

    def on_model_change(self, form, model, is_created):
        # Custom code to call URL
        # Custom code to save to DB
        ...

admin = Admin(app)
admin.add_view(MyModelViewView(MyModel, db.session))
