Overview
Constructs a service interface object. Each API operation is exposed as a function on service.
Service Description
Amazon Verified Permissions is a permissions management service from Amazon Web Services. You can use Verified Permissions to manage permissions for your application, and authorize user access based on those permissions. Using Verified Permissions, application developers can grant access based on information about the users, resources, and requested actions. You can also evaluate additional information like group membership, attributes of the resources, and session context, such as time of request and IP addresses. Verified Permissions manages these permissions by letting you create and store authorization policies for your applications, such as consumer-facing web sites and enterprise business systems.
Verified Permissions uses Cedar as the policy language to express your permission requirements. Cedar supports both role-based access control (RBAC) and attribute-based access control (ABAC) authorization models.
For more information about configuring, administering, and using Amazon Verified Permissions in your applications, see the Amazon Verified Permissions User Guide.
For more information about the Cedar policy language, see the Cedar Policy Language Guide.
When you write Cedar policies that reference principals, resources and actions, you can define the unique identifiers used for each of those elements. We strongly recommend that you follow these best practices:
-
Use values like universally unique identifiers (UUIDs) for all principal and resource identifiers.
For example, if user
jane
leaves the company, and you later let someone else use the namejane
, then that new user automatically gets access to everything granted by policies that still referenceUser::"jane"
. Cedar can’t distinguish between the new user and the old. This applies to both principal and resource identifiers. Always use identifiers that are guaranteed unique and never reused to ensure that you don’t unintentionally grant access because of the presence of an old identifier in a policy.Where you use a UUID for an entity, we recommend that you follow it with the // comment specifier and the ‘friendly’ name of your entity. This helps to make your policies easier to understand. For example: principal == User::"a1b2c3d4-e5f6-a1b2-c3d4-EXAMPLE11111", // alice
-
Do not include personally identifying, confidential, or sensitive information as part of the unique identifier for your principals or resources. These identifiers are included in log entries shared in CloudTrail trails.
Several operations return structures that appear similar, but have different purposes. As new functionality is added to the product, the structure used in a parameter of one operation might need to change in a way that wouldn't make sense for the same parameter in a different operation. To help you understand the purpose of each, the following naming convention is used for the structures:
-
Parameter type structures that end in
Detail
are used inGet
operations. -
Parameter type structures that end in
Item
are used inList
operations. -
Parameter type structures that use neither suffix are used in the mutating (create and update) operations.
Sending a Request Using VerifiedPermissions
var verifiedpermissions = new AWS.VerifiedPermissions();
verifiedpermissions.batchIsAuthorized(params, function (err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
Locking the API Version
In order to ensure that the VerifiedPermissions object uses this specific API, you can
construct the object by passing the apiVersion
option to the constructor:
var verifiedpermissions = new AWS.VerifiedPermissions({apiVersion: '2021-12-01'});
You can also set the API version globally in AWS.config.apiVersions
using
the verifiedpermissions service identifier:
AWS.config.apiVersions = {
verifiedpermissions: '2021-12-01',
// other service API versions
};
var verifiedpermissions = new AWS.VerifiedPermissions();

Property Details
Method Details
batchIsAuthorized(params = {}, callback) ⇒ AWS.Request
Makes a series of decisions about multiple authorization requests for one principal or resource. Each request contains the equivalent content of an
IsAuthorized
request: principal, action, resource, and context. Either theprincipal
or theresource
parameter must be identical across all requests. For example, Verified Permissions won't evaluate a pair of requests wherebob
viewsphoto1
andalice
viewsphoto2
. Authorization ofbob
to viewphoto1
andphoto2
, orbob
andalice
to viewphoto1
, are valid batches.The request is evaluated against all policies in the specified policy store that match the entities that you declare. The result of the decisions is a series of
Allow
orDeny
responses, along with the IDs of the policies that produced each decision.The
entities
of aBatchIsAuthorized
API request can contain up to 100 principals and up to 100 resources. Therequests
of aBatchIsAuthorized
API request can contain up to 30 requests.Note: TheBatchIsAuthorized
operation doesn't have its own IAM permission. To authorize this operation for Amazon Web Services principals, include the permissionverifiedpermissions:IsAuthorized
in their IAM policies.batchIsAuthorizedWithToken(params = {}, callback) ⇒ AWS.Request
Makes a series of decisions about multiple authorization requests for one token. The principal in this request comes from an external identity source in the form of an identity or access token, formatted as a JSON web token (JWT). The information in the parameters can also define additional context that Verified Permissions can include in the evaluations.
The request is evaluated against all policies in the specified policy store that match the entities that you provide in the entities declaration and in the token. The result of the decisions is a series of
Allow
orDeny
responses, along with the IDs of the policies that produced each decision.The
entities
of aBatchIsAuthorizedWithToken
API request can contain up to 100 resources and up to 99 user groups. Therequests
of aBatchIsAuthorizedWithToken
API request can contain up to 30 requests.Note: TheBatchIsAuthorizedWithToken
operation doesn't have its own IAM permission. To authorize this operation for Amazon Web Services principals, include the permissionverifiedpermissions:IsAuthorizedWithToken
in their IAM policies.createIdentitySource(params = {}, callback) ⇒ AWS.Request
Adds an identity source to a policy store–an Amazon Cognito user pool or OpenID Connect (OIDC) identity provider (IdP).
After you create an identity source, you can use the identities provided by the IdP as proxies for the principal in authorization queries that use the IsAuthorizedWithToken or BatchIsAuthorizedWithToken API operations. These identities take the form of tokens that contain claims about the user, such as IDs, attributes and group memberships. Identity sources provide identity (ID) tokens and access tokens. Verified Permissions derives information about your user and session from token claims. Access tokens provide action
context
to your policies, and ID tokens provide principalAttributes
.Tokens from an identity source user continue to be usable until they expire. Token revocation and resource deletion have no effect on the validity of a token in your policy store
Note: To reference a user from this identity source in your Cedar policies, refer to the following syntax examples.- Amazon Cognito user pool:
Namespace::[Entity type]::[User pool ID]|[user principal attribute]
, for exampleMyCorp::User::us-east-1_EXAMPLE|a1b2c3d4-5678-90ab-cdef-EXAMPLE11111
. - OpenID Connect (OIDC) provider:
Namespace::[Entity type]::[principalIdClaim]|[user principal attribute]
, for exampleMyCorp::User::MyOIDCProvider|a1b2c3d4-5678-90ab-cdef-EXAMPLE22222
.
Note: Verified Permissions is eventually consistent . It can take a few seconds for a new or changed element to propagate through the service and be visible in the results of other Verified Permissions operations.createPolicy(params = {}, callback) ⇒ AWS.Request
Creates a Cedar policy and saves it in the specified policy store. You can create either a static policy or a policy linked to a policy template.
-
To create a static policy, provide the Cedar policy text in the
StaticPolicy
section of thePolicyDefinition
. -
To create a policy that is dynamically linked to a policy template, specify the policy template ID and the principal and resource to associate with this policy in the
templateLinked
section of thePolicyDefinition
. If the policy template is ever updated, any policies linked to the policy template automatically use the updated template.
Note: Creating a policy causes it to be validated against the schema in the policy store. If the policy doesn't pass validation, the operation fails and the policy isn't stored.Note: Verified Permissions is eventually consistent . It can take a few seconds for a new or changed element to propagate through the service and be visible in the results of other Verified Permissions operations.createPolicyStore(params = {}, callback) ⇒ AWS.Request
Creates a policy store. A policy store is a container for policy resources.
Note: Although Cedar supports multiple namespaces, Verified Permissions currently supports only one namespace per policy store.Note: Verified Permissions is eventually consistent . It can take a few seconds for a new or changed element to propagate through the service and be visible in the results of other Verified Permissions operations.createPolicyTemplate(params = {}, callback) ⇒ AWS.Request
Creates a policy template. A template can use placeholders for the principal and resource. A template must be instantiated into a policy by associating it with specific principals and resources to use for the placeholders. That instantiated policy can then be considered in authorization decisions. The instantiated policy works identically to any other policy, except that it is dynamically linked to the template. If the template changes, then any policies that are linked to that template are immediately updated as well.
Note: Verified Permissions is eventually consistent . It can take a few seconds for a new or changed element to propagate through the service and be visible in the results of other Verified Permissions operations.deleteIdentitySource(params = {}, callback) ⇒ AWS.Request
Deletes an identity source that references an identity provider (IdP) such as Amazon Cognito. After you delete the identity source, you can no longer use tokens for identities from that identity source to represent principals in authorization queries made using IsAuthorizedWithToken. operations.
deletePolicy(params = {}, callback) ⇒ AWS.Request
Deletes the specified policy from the policy store.
This operation is idempotent; if you specify a policy that doesn't exist, the request response returns a successful
HTTP 200
status code.deletePolicyStore(params = {}, callback) ⇒ AWS.Request
Deletes the specified policy store.
This operation is idempotent. If you specify a policy store that does not exist, the request response will still return a successful HTTP 200 status code.
deletePolicyTemplate(params = {}, callback) ⇒ AWS.Request
Deletes the specified policy template from the policy store.
This operation also deletes any policies that were created from the specified policy template. Those policies are immediately removed from all future API responses, and are asynchronously deleted from the policy store.
getIdentitySource(params = {}, callback) ⇒ AWS.Request
Retrieves the details about the specified identity source.
getPolicyTemplate(params = {}, callback) ⇒ AWS.Request
Retrieve the details for the specified policy template in the specified policy store.
getSchema(params = {}, callback) ⇒ AWS.Request
Retrieve the details for the specified schema in the specified policy store.
isAuthorized(params = {}, callback) ⇒ AWS.Request
Makes an authorization decision about a service request described in the parameters. The information in the parameters can also define additional context that Verified Permissions can include in the evaluation. The request is evaluated against all matching policies in the specified policy store. The result of the decision is either
Allow
orDeny
, along with a list of the policies that resulted in the decision.isAuthorizedWithToken(params = {}, callback) ⇒ AWS.Request
Makes an authorization decision about a service request described in the parameters. The principal in this request comes from an external identity source in the form of an identity token formatted as a JSON web token (JWT). The information in the parameters can also define additional context that Verified Permissions can include in the evaluation. The request is evaluated against all matching policies in the specified policy store. The result of the decision is either
Allow
orDeny
, along with a list of the policies that resulted in the decision.At this time, Verified Permissions accepts tokens from only Amazon Cognito.
Verified Permissions validates each token that is specified in a request by checking its expiration date and its signature.
Tokens from an identity source user continue to be usable until they expire. Token revocation and resource deletion have no effect on the validity of a token in your policy store
listIdentitySources(params = {}, callback) ⇒ AWS.Request
Returns a paginated list of all of the identity sources defined in the specified policy store.
listPolicies(params = {}, callback) ⇒ AWS.Request
Returns a paginated list of all policies stored in the specified policy store.
listPolicyStores(params = {}, callback) ⇒ AWS.Request
Returns a paginated list of all policy stores in the calling Amazon Web Services account.
listPolicyTemplates(params = {}, callback) ⇒ AWS.Request
Returns a paginated list of all policy templates in the specified policy store.
putSchema(params = {}, callback) ⇒ AWS.Request
Creates or updates the policy schema in the specified policy store. The schema is used to validate any Cedar policies and policy templates submitted to the policy store. Any changes to the schema validate only policies and templates submitted after the schema change. Existing policies and templates are not re-evaluated against the changed schema. If you later update a policy, then it is evaluated against the new schema at that time.
Note: Verified Permissions is eventually consistent . It can take a few seconds for a new or changed element to propagate through the service and be visible in the results of other Verified Permissions operations.updateIdentitySource(params = {}, callback) ⇒ AWS.Request
Updates the specified identity source to use a new identity provider (IdP), or to change the mapping of identities from the IdP to a different principal entity type.
Note: Verified Permissions is eventually consistent . It can take a few seconds for a new or changed element to propagate through the service and be visible in the results of other Verified Permissions operations.updatePolicy(params = {}, callback) ⇒ AWS.Request
Modifies a Cedar static policy in the specified policy store. You can change only certain elements of the UpdatePolicyDefinition parameter. You can directly update only static policies. To change a template-linked policy, you must update the template instead, using UpdatePolicyTemplate.
Note:- If policy validation is enabled in the policy store, then updating a static policy causes Verified Permissions to validate the policy against the schema in the policy store. If the updated static policy doesn't pass validation, the operation fails and the update isn't stored.
- When you edit a static policy, you can change only certain elements of a static policy:
- The action referenced by the policy.
- A condition clause, such as when and unless.
- Changing a policy from a static policy to a template-linked policy.
- Changing the effect of a static policy from permit or forbid.
- The principal referenced by a static policy.
- The resource referenced by a static policy.
- To update a template-linked policy, you must update the template instead.
Note: Verified Permissions is eventually consistent . It can take a few seconds for a new or changed element to propagate through the service and be visible in the results of other Verified Permissions operations.updatePolicyStore(params = {}, callback) ⇒ AWS.Request
Modifies the validation setting for a policy store.
Note: Verified Permissions is eventually consistent . It can take a few seconds for a new or changed element to propagate through the service and be visible in the results of other Verified Permissions operations.updatePolicyTemplate(params = {}, callback) ⇒ AWS.Request
Updates the specified policy template. You can update only the description and the some elements of the policyBody.
Changes you make to the policy template content are immediately (within the constraints of eventual consistency) reflected in authorization decisions that involve all template-linked policies instantiated from this template.
Note: Verified Permissions is eventually consistent . It can take a few seconds for a new or changed element to propagate through the service and be visible in the results of other Verified Permissions operations.waitFor(state, params = {}, callback) ⇒ AWS.Request
Waits for a given VerifiedPermissions resource. The final callback or 'complete' event will be fired only when the resource is either in its final state or the waiter has timed out and stopped polling for the final state.
