JWT Auth Policy

The Open ID JWT Authentication policy allows you to authenticate incoming requests using an Open ID-compliant bearer token. It works with common authentication services like Auth0 (sample here) but should also work with any valid Open ID JWT token.

When configured, you can have Zuplo check incoming requests for a JWT token and automatically populate the ZuploRequest 's user property with a user object. This user object will have a sub property - taking the sub id from the JWT token. It will also have a data property populated by other data returned in the JWT token (including any claims).

See this document for more information about OAuth authorization in Zuplo.

Configuration

{
  "name": "my-open-id-jwt-auth-inbound-policy",
  "policyType": "open-id-jwt-auth-inbound",
  "handler": {
    "export": "OpenIdJwtInboundPolicy",
    "module": "$import(@zuplo/runtime)",
    "options": {
      "allowUnauthenticatedRequests": false,
      "audience": "$env(AUTH_AUDIENCE)",
      "issuer": "$env(AUTH_ISSUER)",
      "jwkUrl": "$env(JWK_URL)"
    }
  }
}

• name the name of your policy instance. This is used as a reference in your routes.
• policyType the identifier of the policy. This is used by the Zuplo UI. Value should be open-id-jwt-auth-inbound.
• handler/export The name of the exported type. Value should be OpenIdJwtInboundPolicy.
• handler/module the module containing the policy. Value should be $import(@zuplo/runtime).
• handler/options The options for this policy:
  • issuer
    [object Object]
  • audience
    [object Object]
  • jwkUrl
    [object Object]
  • secret
    [object Object]
  • allowUnauthenticatedRequests
    [object Object]

Note that sometimes the issuer and audience will vary between your environments (e.g. dev, staging and prod). We recommend storing these values in your environment variables and using $env(VARIABLE_NAME) to include them in your policy configuration.

note

Note you can have multiple instances of the same policy with different names if you want to have slightly different rules (such as settings for the allowUnauthenticatedRequests setting.

{
  "path": "/products/:123",
  "methods": ["POST"],
  "handler": {
    "module": "$import(./modules/products)",
    "export": "postProducts"
  },
  "corsPolicy": "None",
  "version": "none",
  "policies": {
    "inbound": ["your-jwt-policy-name"]
  }
}
