# DescribeAccessPoints
Returns the description of a specific Amazon EFS access point if the `AccessPointId` is provided. If you provide an EFS `FileSystemId`, it returns descriptions of all access points for that file system. You can provide either an `AccessPointId` or a `FileSystemId` in the request, but not both.
This operation requires permissions for the `elasticfilesystem:DescribeAccessPoints` action.
## Request Syntax
```
GET /2015-02-01/access-points?AccessPointId=AccessPointId&FileSystemId=FileSystemId&MaxResults=MaxResults&NextToken=NextToken HTTP/1.1
```
## URI Request Parameters
The request uses the following URI parameters.
** [AccessPointId](#API_DescribeAccessPoints_RequestSyntax) **
(Optional) Specifies an EFS access point to describe in the response; mutually exclusive with `FileSystemId`.
Length Constraints: Maximum length of 128.
Pattern: `^(arn:aws[-a-z]*:elasticfilesystem:[0-9a-z-:]+:access-point/fsap-[0-9a-f]{8,40}|fsap-[0-9a-f]{8,40})$`
** [FileSystemId](#API_DescribeAccessPoints_RequestSyntax) **
(Optional) If you provide a `FileSystemId`, EFS returns all access points for that file system; mutually exclusive with `AccessPointId`.
Length Constraints: Maximum length of 128.
Pattern: `^(arn:aws[-a-z]*:elasticfilesystem:[0-9a-z-:]+:file-system/fs-[0-9a-f]{8,40}|fs-[0-9a-f]{8,40})$`
** [MaxResults](#API_DescribeAccessPoints_RequestSyntax) **
(Optional) When retrieving all access points for a file system, you can optionally specify the `MaxItems` parameter to limit the number of objects returned in a response. The default value is 100.
Valid Range: Minimum value of 1.
** [NextToken](#API_DescribeAccessPoints_RequestSyntax) **
`NextToken` is present if the response is paginated. You can use `NextMarker` in the subsequent request to fetch the next page of access point descriptions.
Length Constraints: Minimum length of 1. Maximum length of 128.
Pattern: `.+`

## Errors
** AccessPointNotFound **
Returned if the specified `AccessPointId` value doesn't exist in the requester's AWS account.
** ErrorCode **
The error code is a string that uniquely identifies an error condition. It is meant to be read and understood by programs that detect and handle errors by type.
** Message **
The error message contains a generic description of the error condition in English. It is intended for a human audience. Simple programs display the message directly to the end user if they encounter an error condition they don't know how or don't care to handle. Sophisticated programs with more exhaustive error handling and proper internationalization are more likely to ignore the error message.
HTTP Status Code: 404
** BadRequest **
Returned if the request is malformed or contains an error such as an invalid parameter value or a missing required parameter.
