Why use Response Schema Validator?
Contracts drift: mobile clients expect fields APIs no longer send. Validate a JSON payload against JSON Schema draft-07 to catch missing properties, wrong types, and enum violations before deploy, especially for public partner APIs.
Practical tips
- Start with required fields only, then tighten optional properties gradually.
- Keep schemas in version control next to OpenAPI or AsyncAPI docs.
- Use JSON Diff on responses when schemas fail to spot unexpected removals.
Common questions
- Which JSON Schema version?
- Draft-07 as noted in-tool. Newer drafts may need feature checks in your validator library.
- Does this validate GraphQL responses?
- It validates arbitrary JSON. For GraphQL query syntax use GraphQL Query Validator.
