Auth0

Auth0 API Skill

Overview

Auth0 provides Authentication as a Service. This skill focuses on the Management API for backend operations (users, roles, permissions).

Installation

npm install auth0
pip install auth0-python

Authentication

Authenticate against the Management API using an OAuth2 Machine-to-Machine (M2M) token fetched from your tenant's /oauth/token endpoint.

Core Concepts

• Tenant: Your isolated Auth0 instance.
• Connection: A source of users (e.g., Database, Google OAuth).
• Rules/Actions: Serverless functions triggered during authentication.

Common Workflows

1. Obtain a Management API Token (cache this).
2. Initialize ManagementClient.
3. Perform actions like client.users.update({ id }, data).

Error Handling

Catch API errors. Watch for HTTP 429 (Rate Limit Exceeded) and HTTP 400 (Validation Error, such as invalid password strength).

Security

Management API tokens have massive power. Ensure they are scoped strictly to the resources they need (e.g., read:users rather than update:users if only reading).

Rate Limits

Limits depend on your subscription tier. The Management API is strictly rate-limited; heavily cache user profiles in your own database.

Best Practices

Do not call the Management API on every user login. Use Auth0 Actions to inject custom claims into the ID Token instead.

Troubleshooting

If M2M token generation fails, verify that your Machine-to-Machine application is authorized to access the Auth0 Management API resource server.

Why use this skill

Use this when your agent works with auth0 — structured patterns beat pasted docs and prevent common hallucinations.

AI pitfalls

• Using outdated SDK or API versions from training data
• Inventing environment variable names
• Omitting error handling and retry logic

Production checklist

• [ ] Secrets in environment variables, not source code
• [ ] Error handling and logging in place
• [ ] Rate limits and timeouts configured
