# ListPermissions
Retrieves a list of available Amazon RAM permissions that you can use for the supported resource types.
**Note**
Always check the `NextToken` response parameter for a `null` value when calling a paginated operation. These operations can occasionally return an empty set of results even when there are more results available. The `NextToken` response parameter value is `null` *only* when there are no more results to display.
## Request Syntax
```
POST /listpermissions HTTP/1.1
Content-type: application/json
{
"maxResults": number,
"nextToken": "string",
"permissionType": "string",
"resourceType": "string"
}
```
## URI Request Parameters
The request does not use any URI parameters.
## Request Body
The request accepts the following data in JSON format.
** [maxResults](#API_ListPermissions_RequestSyntax) **
Specifies the total number of results that you want included on each page of the response. If you do not include this parameter, it defaults to a value that is specific to the operation. If additional items exist beyond the number you specify, the `NextToken` response element is returned with a value (not null). Include the specified value as the `NextToken` request parameter in the next call to the operation to get the next part of the results. Note that the service might return fewer results than the maximum even when there are more results available. You should check `NextToken` after every operation to ensure that you receive all of the results.
Type: Integer
Valid Range: Minimum value of 1. Maximum value of 500.
Required: No
** [nextToken](#API_ListPermissions_RequestSyntax) **
Specifies that you want to receive the next page of results. Valid only if you received a `NextToken` response in the previous request. If you did, it indicates that more output is available. Set this parameter to the value provided by the previous call's `NextToken` response to request the next page of results.
Type: String
Required: No
** [permissionType](#API_ListPermissions_RequestSyntax) **
Specifies that you want to list only permissions of this type:
+ `AWS` – returns only Amazon managed permissions.
+ `LOCAL` – returns only customer managed permissions
+ `ALL` – returns both Amazon managed permissions and customer managed permissions.
If you don't specify this parameter, the default is `All`.
Type: String
Valid Values: `ALL | AWS_MANAGED | CUSTOMER_MANAGED`
Required: No
** [resourceType](#API_ListPermissions_RequestSyntax) **
Specifies that you want to list only those permissions that apply to the specified resource type. This parameter is not case sensitive.
For example, to list only permissions that apply to Amazon EC2 subnets, specify `ec2:subnet`. You can use the [ListResourceTypes](API_ListResourceTypes.md) operation to get the specific string required.
Type: String
Required: No
## Response Syntax
```
HTTP/1.1 200
Content-type: application/json
{
"nextToken": "string",
"permissions": [
{
"arn": "string",
"creationTime": number,
"defaultVersion": boolean,
"featureSet": "string",
"isResourceTypeDefault": boolean,
"lastUpdatedTime": number,
"name": "string",
"permissionType": "string",
"resourceType": "string",
"status": "string",
"tags": [
{
"key": "string",
"value": "string"
}
],
"version": "string"
}
]
}
```
## Response Elements
If the action is successful, the service sends back an HTTP 200 response.
The following data is returned in JSON format by the service.
** [nextToken](#API_ListPermissions_ResponseSyntax) **
If present, this value indicates that more output is available than is included in the current response. Use this value in the `NextToken` request parameter in a subsequent call to the operation to get the next part of the output. You should repeat this until the `NextToken` response element comes back as `null`. This indicates that this is the last page of results.
Type: String
** [permissions](#API_ListPermissions_ResponseSyntax) **
An array of objects with information about the permissions.
Type: Array of [ResourceSharePermissionSummary](API_ResourceSharePermissionSummary.md) objects
## Errors
