Policy Validation and Dependencies
The following table lists the following:
- Policy dependencies; whether a policy must be used in conjunction with another particular policy.
- Conflicting or incompatible policies.
- Whether a policy can be included multiple times in a single API. If a policy cannot be included multiple times in a single API, API Gateway selects one, depending on the precedence of the policy at the enforcement level, for the effective policy and processes at run-time.
