What it writes
- API authentication options comparison table
- Plain-language protocol explanation
- API authentication planning checklist
How to use it
In your first message, name each client type, the API resources and actions it needs, and any constraints such as SSO, mobile use, or third-party access. That makes the trade-offs specific.
What you bring
- API type and intended clients
- Resources and actions each client needs
- Security or platform constraints
- Know who needs API access
A good fit for
- Choosing between API keys and OAuth for a partner integration
- Explaining an unfamiliar authentication protocol to your engineering team
- Planning access for a mobile app and its backend API
Ways to start
A few requests this Agent can handle.
Our partner system needs read-only access to order status through our REST API. Compare API keys and OAuth client credentials, including credential rotation and revocation.
Explain OAuth authorization code with PKCE for our mobile app, which accesses a user's profile and order history through our backend.
Make an authentication planning checklist for an internal reporting API used by 40 employees, with read-only access and SSO already in place.
Good to know
This workspace provides text assistance.
