# TagResource
<a name="API_TagResource"></a>

Assigns one or more tags (key-value pairs) to the specified Amazon Verified Permissions resource. Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values. In Verified Permissions, policy stores can be tagged.

Tags don't have any semantic meaning to AWS and are interpreted strictly as strings of characters.

You can use the TagResource action with a resource that already has tags. If you specify a new tag key, this tag is appended to the list of tags associated with the resource. If you specify a tag key that is already associated with the resource, the new tag value that you specify replaces the previous value for that tag.

You can associate as many as 50 tags with a resource.

For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).

 ** AccessDeniedException **   
You don't have sufficient access to perform this action.  
HTTP Status Code: 400

 ** InternalServerException **   
The request failed because of an internal error. Try your request again later  
HTTP Status Code: 500

 ** ResourceNotFoundException **   
The request failed because it references a resource that doesn't exist.    
 ** resourceId **   
The unique ID of the resource referenced in the failed request.  
 ** resourceType **   
The resource type of the resource referenced in the failed request.
HTTP Status Code: 400

 ** ThrottlingException **   
The request failed because it exceeded a throttling quota.    
 ** quotaCode **   
The quota code recognized by the AWS Service Quotas service.  
 ** serviceCode **   
The code for the AWS service that owns the quota.
HTTP Status Code: 400

 ** TooManyTagsException **   
No more tags be added because the limit (50) has been reached. To add new tags, use `UntagResource` to remove existing tags.  
HTTP Status Code: 400

 ** ValidationException **   
The request failed because one or more input parameters don't satisfy their constraint requirements. The output is provided as a list of fields and a reason for each field that isn't valid.  
The possible reasons include the following:  
+  **UnrecognizedEntityType** 

  The policy includes an entity type that isn't found in the schema.
+  **UnrecognizedActionId** 

  The policy includes an action id that isn't found in the schema.
+  **InvalidActionApplication** 

  The policy includes an action that, according to the schema, doesn't support the specified principal and resource.
+  **UnexpectedType** 

  The policy included an operand that isn't a valid type for the specified operation.
+  **IncompatibleTypes** 

  The types of elements included in a `set`, or the types of expressions used in an `if...then...else` clause aren't compatible in this context.
+  **MissingAttribute** 

  The policy attempts to access a record or entity attribute that isn't specified in the schema. Test for the existence of the attribute first before attempting to access its value. For more information, see the [has (presence of attribute test) operator](https://docs.cedarpolicy.com/policies/syntax-operators.html#has-presence-of-attribute-test) in the *Cedar Policy Language Guide*.
+  **UnsafeOptionalAttributeAccess** 

  The policy attempts to access a record or entity attribute that is optional and isn't guaranteed to be present. Test for the existence of the attribute first before attempting to access its value. For more information, see the [has (presence of attribute test) operator](https://docs.cedarpolicy.com/policies/syntax-operators.html#has-presence-of-attribute-test) in the *Cedar Policy Language Guide*.
+  **ImpossiblePolicy** 

  Cedar has determined that a policy condition always evaluates to false. If the policy is always false, it can never apply to any query, and so it can never affect an authorization decision.
+  **WrongNumberArguments** 

  The policy references an extension type with the wrong number of arguments.
+  **FunctionArgumentValidationError** 

  Cedar couldn't parse the argument passed to an extension type. For example, a string that is to be parsed as an IPv4 address can contain only digits and the period character.  
 ** fieldList **   
The list of fields that aren't valid.
HTTP Status Code: 400
