API Testing Examples

Review practical endpoint, payload and error-handling examples that support backend quality.

What this example shows

API testing examples should show more than a successful request. Useful checks include auth, required fields, invalid payloads, response status, schema consistency and clear error messages.

Example situations

✓ Missing required field returns unclear error
✓ Expired state produces inconsistent response
✓ Response schema differs between success and failure paths

Copyable example block

Endpoint: POST /api/v1/offers
Checks:
- Auth required
- Missing required fields
- Invalid numeric boundaries
- Response status codes
- Error message clarity
Result: inconsistent validation response when amount exceeds max boundary
