Simulate how a set of IAM policies attached to an IAM entity works with a list of API actions and AWS resources to determine the policies' effective permissions. The entity can be an IAM user, group, or role. If you specify a user, then the simulation also includes all of the policies that are attached to groups that the user belongs to .

You can optionally include a list of one or more additional policies specified as strings to include in the simulation. If you want to simulate only policies specified as strings, use SimulateCustomPolicy instead.

You can also optionally include one resource-based policy to be evaluated with each of the resources included in the simulation.

The simulation does not perform the API actions, it only checks the authorization to determine if the simulated policies allow or deny the actions.

Note: This API discloses information about the permissions granted to other

users. If you do not want users to see other user's permissions, then consider allowing them to use SimulateCustomPolicy instead.

Context keys are variables maintained by AWS and its services that provide details about the context of an API query request. You can use the Condition element of an IAM policy to evaluate context keys. To get the list of context keys that the policies require for correct simulation, use GetContextKeysForPrincipalPolicy.

If the output is long, you can use the MaxItems and Marker parameters to paginate the results.
