Frequently Asked Questions
- Can I test authenticated API endpoints?
- Yes. Add Authorization headers (Bearer token, API key, Basic auth) in the request headers field. Credentials are encrypted in transit and never stored.
- What is the difference between API Deep-Scan and a regular health check?
- A health check only verifies the endpoint returns 200 OK. API Deep-Scan validates the full response: correct status code, response body structure, header values, CORS configuration, authentication, and performance from multiple regions.
- Can I test GraphQL APIs?
- Yes. Set method to POST, Content-Type to application/json, and include your GraphQL query in the request body.
