Successful JSON and status-only responses vary by operation. The service does not declare a stable response schema for this operation; do not assume a collection envelope or undocumented fields. ## OpenAPI ````yaml /openapi-shield.json post /shield/domains/{domain_id}/default-rule-overrides openapi: 3.1.0 info: title: Aptranet Cloud Shield API version: 1.0.0 description: >- Public project-scoped API. Use the access key and secret together. Browser-only organization administration is documented separately. Request schemas and query parameters follow the service operation allowlist. Plan entitlements apply in addition to API permissions. Some analytics and action responses have operation-specific JSON shapes; where the implementation provides no stable response contract, the reference deliberately does not invent one. servers: - url: https://api.aptranet.com security: - bearerAuth: [] apiSecret: [] paths: /shield/domains/{domain_id}/default-rule-overrides: post: tags: - Cloud Shield Policy Overrides summary: Create a policy override description: >- Project-scoped operation.
