This example demonstrates how you can use the new AWS HTTP API (Announced Dec. 2019) and the built in JSON Web Token Authorization it offers. In this case, I've shown how to do so assuming that you've already been working with a tool like Cognito, Auth0 or Okta and have an issuerUrl and audience to add into the code.
Depending on your implementation and the tool, the audience could be something like an Auth0 API ID or a Cognito App Client ID.
