How to Validate JSON API Responses

Problem: Ensure API responses are valid JSON and contain required fields.

Steps

1. Paste the response into JSON Formatter to check syntax.
2. Use JSON Viewer to inspect required fields.
3. For automated checks, extract key fields and compare against expected values using Text Compare.

Example

{"id":123,"status":"ok"}

Confirm id exists and is numeric; confirm status is expected.
