Authentication

Iron Functions API supports two levels of Authentication in two seperate scopes, using JWT tokens for authentication.

  • Service level authentication
  • Route level authentication.

Service level authentication

This authenticates all requests made to the server from any client. Service level authentication is set by the JWT_AUTH_KEY environment variable. If you set with variable within the server context, the server will look for a valid JWT token in every request. For use with the fn tool, you also need to set this environment variable within fn tool context while calling a command.

Route level authentication

Route level authentication is applied whenever a function call made to a specific route. You can check Quick Example for JWT Authentication for an example.
