Files for API Testing

A collection of sample files designed for testing REST APIs, GraphQL endpoints, webhook handlers, and data exchange services. Includes realistic JSON payloads, XML documents, CSV exports, and webhook event data in various sizes. Test request/response handling, content negotiation, payload parsing, error responses, and rate limiting with these files.

Frequently Asked Questions

What file sizes should I test API endpoints with?

Test with small payloads (1–10KB) for functional testing, medium payloads (100KB–1MB) for performance testing, and large payloads (10MB+) for timeout and memory testing.

How do I test API error handling?

Send invalid JSON, malformed XML, empty payloads, and oversized files to your endpoints. Verify that your API returns proper HTTP status codes (400, 413, 415) with descriptive error messages.
