API Specifications and Policy Contracts
Align API specifications with configured policy inputs, accepted token and payload forms, intercepted methods and gateway-generated responses.
Identify any change(s) required to an API specification to reflect the application of an API policy with specific characteristics.
~7 min read · 5 practice questions
What the exam expects
- Update an API contract when a policy changes required request credentials or accepted structure.
- Document policy-generated responses as well as implementation responses.
- Check whether a gateway policy intercepts a method the implementation expects to receive.
- Align token representations and constraints with the selected validation policy.
An API specification describes the consumer-facing contract; a RAML trait reuses method requirements; a policy configuration determines runtime enforcement; JWS is the signed JWT representation supported by this validator; a structural limit constrains an XML request's shape or content lengths (Client ID Enforcement, JWT Validation, XML protection).
Key facts
Credential placement
- Detail
- Match the specification to the configured extraction location.
Reusable requirement
- Detail
- A trait can declare required fields and be applied with
is.
REST quota exhaustion
- Detail
- Standard Rate Limiting rejects excess requests with HTTP 429.
Quota metadata
- Detail
- Enabled exposure adds limit, remaining quota and reset information.
Protected OPTIONS
- Detail
- CORS handles it as preflight rather than forwarding to the application.
JWT representation
- Detail
- JWT Validation supports JWS, not JWE.
XML attribute allowance
- Detail
- Per element, excluding namespace declarations.
XML rejection
- Detail
- Structural-policy rejection returns HTTP 400.
- When a downstream flow needs a claim after JWT Validation succeeds, which property path exposes it?
- When interpreting Maximum Comment Length for XML, what does the setting measure?
- Why does an XML node-depth limit not bound the length of a text node?
