Secure Model APIs with Auth0 Resource Servers
PythonTo secure your Model APIs using Auth0, you will typically create a "Resource Server" in Auth0 which represents your API. A Resource Server is an OAuth 2.0 term and it refers to your API as a service that can authenticate access tokens. Once set up, your API will be able to validate incoming access tokens, ensure they're coming from an authenticated source, and grant or deny access to the resources it serves based on scopes or permissions included within these tokens.
In this Pulumi program, we will set up an Auth0 Resource Server by creating an instance of
auth0.ResourceServer
. This will involve specifying the identifier, which uniquely identifies your API, setting the signing algorithm to verify the tokens, and other specifics such as the token lifetime and scopes that define the permissions clients can request.Each scope is essentially a permission that is granted to the access token. For example, if your API has an endpoint to 'read' user information and another to 'write' user information, you could have two scopes:
read:user
andwrite:user
. Clients will request these scopes, and their tokens will be marked with them, allowing for fine-grained access control.Here's a basic Pulumi program in Python to create an Auth0 Resource Server:
import pulumi import pulumi_auth0 as auth0 # Create a new Resource Server (API) in Auth0. # The `identifier` should be a unique URI for the resource server, typically it is the base URL for your API. # The `scopes` define the different permissions that tokens can request or include. # Replace 'https://myapi.example.com/' with your actual API identifier, and define relevant scopes. resource_server = auth0.ResourceServer("my-api-resource-server", name="My API", identifier="https://myapi.example.com/", # The unique identifier for your API scopes=[ {"value": "read:user", "description": "Read user information"}, {"value": "write:user", "description": "Write user information"} ], signing_alg="RS256", # The recommended signing algorithm, using RS256 provides asymmetric signing. token_lifetime=86400, # Tokens validity in seconds (86400 seconds equals 24 hours). enforce_policies=True, # Whether to enforce the configured policies for this API. token_dialect="access_token", # The access token format, recommended to use 'access_token' explicitly. skip_consent_for_verifiable_first_party_clients=True # Typically true for machine to machine APIs. ) # Export the ID of the resource server, which is useful for integration and management. pulumi.export("resource_server_id", resource_server.id)
In the above code:
- We create a Resource Server with
auth0.ResourceServer
. - Set
name
to a friendly name for the Resource Server. - Set
identifier
to a unique URI that represents your API. - Define a list of
scopes
representing the specific actions/permissions clients can request. - Select
signing_alg
which determines the algorithm used to sign the tokens sent to your API.
This Pulumi resource will manage the creation, configuration, and lifecycle of your Auth0 Resource Server. When you run the program with Pulumi, it will provision this server on Auth0, allowing you to secure your own Model APIs with the created configurations.
Please visit the auth0.ResourceServer documentation for more information on the arguments and usage of this resource.
