Gets a list of all of the context keys referenced in the input policies. The policies are supplied as a list of one or more strings. To get the context keys from policies associated with an IAM user, group, or role, use GetContextKeysForPrincipalPolicy.

Context keys are variables maintained by Amazon Web Services and its services that provide details about the context of an API query request. Context keys can be evaluated by testing against a value specified in an IAM policy. Use GetContextKeysForCustomPolicy to understand what key names and values you must supply when you call SimulateCustomPolicy. Note that all parameters are shown in unencoded form here for clarity but must be URL encoded to be included as a part of a real HTML request.
