Add policies to your functions to specify who has access to what.
Our policies are middlewares: a fragment of code that runs before the function runs itself. These policies can implement validation functionalities that provide features like security, resolve external data, etc., and have the benefit of saving you from having to code and maintain these functionalities on your own.
For now, we have only implemented policies in callable functions.
This video walks you through the process of adding and removing policies to your callable functions.
