Actions defined by AWS IoT Things Graph

You can specify the following actions in the Action element of an IAM policy statement. Use policies to grant permissions to perform an operation in AWS. When you use an action in a policy, you usually allow or deny access to the API operation or CLI command with the same name. However, in some cases, a single action controls access to more than one operation. Alternatively, some operations require several different actions.

The Resource types column indicates whether each action supports resource-level permissions. If there is no value for this column, you must specify all resources ("*") in the Resource element of your policy statement. If the column includes a resource type, then you can specify an ARN of that type in a statement with that action. Required resources are indicated in the table with an asterisk (*). If you specify a resource-level permission ARN in a statement using this action, then it must be of this type. Some actions support multiple resource types. If the resource type is optional (not indicated as required), then you can choose to use one but not the other.

For details about the columns in the following table, see The actions table.

Actions	Description	Access level	Resource types (*required)	Condition keys	Dependent actions
AssociateEntityToThing	Associates a device with a concrete thing that is in the user's registry. A thing can be associated with only one device at a time. If you associate a thing with a new device id, its previous association will be removed.	Write			iot:DescribeThing iot:DescribeThingGroup
CreateFlowTemplate	Creates a workflow template. Workflows can be created only in the user's namespace. (The public namespace contains only entities.) The workflow can contain only entities in the specified namespace. The workflow is validated against the entities in the latest version of the user's namespace unless another namespace version is specified in the request.	Write
CreateSystemInstance	Creates an instance of a system with specified configurations and Things.	Tagging		aws:RequestTag/${TagKey} aws:TagKeys
CreateSystemTemplate	Creates a system. The system is validated against the entities in the latest version of the user's namespace unless another namespace version is specified in the request.	Write
DeleteFlowTemplate	Deletes a workflow. Any new system or system instance that contains this workflow will fail to update or deploy. Existing system instances that contain the workflow will continue to run (since they use a snapshot of the workflow taken at the time of deploying the system instance).	Write	Workflow*
DeleteNamespace	Deletes the specified namespace. This action deletes all of the entities in the namespace. Delete the systems and flows in the namespace before performing this action.	Write
DeleteSystemInstance	Deletes a system instance. Only instances that have never been deployed, or that have been undeployed from the target can be deleted. Users can create a new system instance that has the same ID as a deleted system instance.	Write	SystemInstance*
DeleteSystemTemplate	Deletes a system. New system instances can't contain the system after its deletion. Existing system instances that contain the system will continue to work because they use a snapshot of the system that is taken when it is deployed.	Write	System*
DeploySystemInstance	Deploys the system instance to the target specified in CreateSystemInstance.	Write	SystemInstance*
DeprecateFlowTemplate	Deprecates the specified workflow. This action marks the workflow for deletion. Deprecated flows can't be deployed, but existing system instances that use the flow will continue to run.	Write	Workflow*
DeprecateSystemTemplate	Deprecates the specified system.	Write	System*
DescribeNamespace	Gets the latest version of the user's namespace and the public version that it is tracking.	Read
DissociateEntityFromThing	Dissociates a device entity from a concrete thing. The action takes only the type of the entity that you need to dissociate because only one entity of a particular type can be associated with a thing.	Write			iot:DescribeThing iot:DescribeThingGroup
GetEntities	Gets descriptions of the specified entities. Uses the latest version of the user's namespace by default.	Read
GetFlowTemplate	Gets the latest version of the DefinitionDocument and FlowTemplateSummary for the specified workflow.	Read	Workflow*
GetFlowTemplateRevisions	Gets revisions of the specified workflow. Only the last 100 revisions are stored. If the workflow has been deprecated, this action will return revisions that occurred before the deprecation. This action won't work for workflows that have been deleted.	Read	Workflow*
GetNamespaceDeletionStatus	Gets the status of a namespace deletion task.	Read
GetSystemInstance	Gets a system instance.	Read	SystemInstance*
GetSystemTemplate	Gets a system.	Read	System*
GetSystemTemplateRevisions	Gets revisions made to the specified system template. Only the previous 100 revisions are stored. If the system has been deprecated, this action will return the revisions that occurred before its deprecation. This action won't work with systems that have been deleted.	Read	System*
GetUploadStatus	Gets the status of the specified upload.	Read
ListFlowExecutionMessages	Lists details of a single workflow execution	List
ListTagsForResource	Lists all tags for a given resource	List	SystemInstance
SearchEntities	Searches for entities of the specified type. You can search for entities in your namespace and the public namespace that you're tracking.	Read
SearchFlowExecutions	Searches for workflow executions of a system instance	Read	SystemInstance*
SearchFlowTemplates	Searches for summary information about workflows.	Read
SearchSystemInstances	Searches for system instances in the user's account.	Read
SearchSystemTemplates	Searches for summary information about systems in the user's account. You can filter by the ID of a workflow to return only systems that use the specified workflow.	Read
SearchThings	Searches for things associated with the specified entity. You can search by both device and device model.	Read
TagResource	Tag a specified resource	Tagging	SystemInstance
				aws:RequestTag/${TagKey} aws:TagKeys
UndeploySystemInstance	Removes the system instance and associated triggers from the target.	Write	SystemInstance*
UntagResource	Untag a specified resource	Tagging	SystemInstance
				aws:TagKeys
UpdateFlowTemplate	Updates the specified workflow. All deployed systems and system instances that use the workflow will see the changes in the flow when it is redeployed. The workflow can contain only entities in the specified namespace.	Write	Workflow*
UpdateSystemTemplate	Updates the specified system. You don't need to run this action after updating a workflow. Any system instance that uses the system will see the changes in the system when it is redeployed.	Write	System*
UploadEntityDefinitions	Asynchronously uploads one or more entity definitions to the user's namespace.	Write

Resource types defined by AWS IoT Things Graph

The following resource types are defined by this service and can be used in the Resource element of IAM permission policy statements. Each action in the Actions table identifies the resource types that can be specified with that action. A resource type can also define which condition keys you can include in a policy. These keys are displayed in the last column of the table. For details about the columns in the following table, see The resource types table.

Resource types	ARN	Condition keys
Workflow	arn:${Partition}:iotthingsgraph:${Region}:${Account}:Workflow/${NamespacePath}
System	arn:${Partition}:iotthingsgraph:${Region}:${Account}:System/${NamespacePath}
SystemInstance	arn:${Partition}:iotthingsgraph:${Region}:${Account}:Deployment/${NamespacePath}	aws:ResourceTag/${TagKey}

Condition keys for AWS IoT Things Graph

AWS IoT Things Graph defines the following condition keys that can be used in the Condition element of an IAM policy. You can use these keys to further refine the conditions under which the policy statement applies. For details about the columns in the following table, see The condition keys table.

To view the global condition keys that are available to all services, see Available global condition keys.

Condition keys	Description	Type
aws:RequestTag/${TagKey}	Filters access by a key that is present in the request the user makes to the thingsgraph service.	String
aws:ResourceTag/${TagKey}	Filters access by a tag key and value pair.	String
aws:TagKeys	Filters access by the list of all the tag key names present in the request the user makes to the thingsgraph service.	String
