Working with API & GraphQL Tools
API work usually involves more than sending a request. Schemas need to stay in sync, examples must match contracts, query complexity matters, and changes that look harmless can break existing consumers. The tools in this category are geared toward inspecting OpenAPI and GraphQL definitions, building requests, comparing schemas, and catching contract problems before they become integration bugs.
Keep generated requests and schema transformations tied to a known API version. OpenAPI 3.0, OpenAPI 3.1, Swagger 2.0, and GraphQL each have details that do not translate perfectly. When comparing versions, pay attention to required fields, nullability, enum changes, authentication schemes, status codes, and renamed operations rather than relying only on a textual diff.
Practical tips
- Validate the schema before generating examples or client-facing documentation from it.
- Treat removed fields, narrower enums, and new required parameters as potential breaking changes.
- For GraphQL, test realistic nested queries when reviewing depth or complexity limits.
- Keep example payloads free of real credentials, personal data, and production identifiers.
- After converting a schema version, run it through the tooling used by your actual clients or gateway.
