# API Reference for Storage Gateway In addition to using the console, you can use the AWS Storage Gateway API to programmatically configure and manage your gateways. This section describes the AWS Storage Gateway operations, request signing for authentication and the error handling. For information about the regions and endpoints available for Storage Gateway, see [AWS Storage Gateway Endpoints and Quotas](https://docs.aws.amazon.com/general/latest/gr/sg.html) in the *AWS General Reference*. **Note** You can also use the AWS SDKs when developing applications with Storage Gateway. The AWS SDKs for Java, .NET, and PHP wrap the underlying Storage Gateway API, simplifying your programming tasks. For information about downloading the SDK libraries, see [Sample Code Libraries](https://aws.amazon.com/code). **Topics** + [AWS Storage Gateway Required Request Headers](#AWSStorageGatewayHTTPRequestsHeaders) + [Signing Requests](#AWSStorageGatewaySigningRequests) + [Error Responses](#APIErrorResponses) + [Storage Gateway API Actions](#AWSStorageGatewayAPIOperations) ## AWS Storage Gateway Required Request Headers This section describes the required headers that you must send with every POST request to AWS Storage Gateway. You include HTTP headers to identify key information about the request including the operation you want to invoke, the date of the request, and information that indicates the authorization of you as the sender of the request. Headers are case insensitive and the order of the headers is not important. The following example shows headers that are used in the [ActivateGateway](https://docs.aws.amazon.com/storagegateway/latest/APIReference/API_ActivateGateway.html) operation. ``` POST / HTTP/1.1 Host: storagegateway.us-east-2.amazonaws.com Content-Type: application/x-amz-json-1.1 Authorization: AWS4-HMAC-SHA256 Credential=AKIAIOSFODNN7EXAMPLE/20120425/us-east-2/storagegateway/aws4_request, SignedHeaders=content-type;host;x-amz-date;x-amz-target, Signature=9cd5a3584d1d67d57e61f120f35102d6b3649066abdd4bf4bbcf05bd9f2f8fe2 x-amz-date: 20120912T120000Z x-amz-target: StorageGateway_20120630.ActivateGateway ``` The following are the headers that must include with your POST requests to AWS Storage Gateway. Headers shown below that begin with "x-amz" are AWS-specific headers. All other headers listed are common header used in HTTP transactions. | Header | Description | | --- | --- | | Authorization | The authorization header contains several of pieces of information about the request that allow AWS Storage Gateway to determine if the request is a valid action for the requester. The format of this header is as follows (line breaks added for readability): 
Authorization: AWS4-HMAC_SHA456 
Credentials=YourAccessKey/yyymmdd/region/storagegateway/aws4_request, 
SignedHeaders=content-type;host;x-amz-date;x-amz-target, 
Signature=CalculatedSignature
In the preceding syntax, you specify *YourAccessKey*, the year, month, and day (*yyyymmdd*), the *region*, and the *CalculatedSignature*. The format of the authorization header is dictated by the requirements of the AWS V4 Signing process. The details of signing are discussed in the topic [Signing Requests](#AWSStorageGatewaySigningRequests). | | Content-Type | Use `application/x-amz-json-1.1` as the content type for all requests to AWS Storage Gateway. 
Content-Type: application/x-amz-json-1.1
| | Host | Use the host header to specify the AWS Storage Gateway endpoint where you send your request. For example, `storagegateway.us-east-2.amazonaws.com` is the endpoint for the US East (Ohio) region. For more information about the endpoints available for AWS Storage Gateway, see [AWS Storage Gateway Endpoints and Quotas](https://docs.aws.amazon.com/general/latest/gr/sg.html) in the *AWS General Reference*. 
Host: storagegateway.region.amazonaws.com
| | x-amz-date | You must provide the time stamp in either the HTTP `Date` header or the AWS `x-amz-date` header. (Some HTTP client libraries don't let you set the `Date` header.) When an `x-amz-date` header is present, the AWS Storage Gateway ignores any `Date` header during the request authentication. The `x-amz-date` format must be ISO8601 Basic in the YYYYMMDD'T'HHMMSS'Z' format. If both the `Date` and `x-amz-date` header are used, the format of the Date header does not have to be ISO8601. 
x-amz-date: YYYYMMDD'T'HHMMSS'Z'
| | x-amz-target | This header specifies the version of the API and the operation that you are requesting. The target header values are formed by concatenating the API version with the API name and are in the following format. 
x-amz-target: StorageGateway_APIversion.operationName
The *operationName* value (e.g. "ActivateGateway") can be found from the API list, [API Reference for Storage Gateway](#AWSStorageGatewayAPI). | ## Signing Requests Storage Gateway requires that you authenticate every request you send by signing the request. To sign a request, you calculate a digital signature using a cryptographic hash function. A cryptographic hash is a function that returns a unique hash value based on the input. The input to the hash function includes the text of your request and your secret access key. The hash function returns a hash value that you include in the request as your signature. The signature is part of the `Authorization` header of your request. After receiving your request, Storage Gateway recalculates the signature using the same hash function and input that you used to sign the request. If the resulting signature matches the signature in the request, Storage Gateway processes the request. Otherwise, the request is rejected. Storage Gateway supports authentication using [AWS Signature Version 4](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html). The process for calculating a signature can be broken into three tasks: + [Task 1: Create a Canonical Request](https://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html) Rearrange your HTTP request into a canonical format. Using a canonical form is necessary because Storage Gateway uses the same canonical form when it recalculates a signature to compare with the one you sent. + [Task 2: Create a String to Sign](https://docs.aws.amazon.com/general/latest/gr/sigv4-create-string-to-sign.html) Create a string that you will use as one of the input values to your cryptographic hash function. The string, called the *string to sign*, is a concatenation of the name of the hash algorithm, the request date, a *credential scope* string, and the canonicalized request from the previous task. The *credential scope* string itself is a concatenation of date, region, and service information. + [Task 3: Create a Signature](https://docs.aws.amazon.com/general/latest/gr/sigv4-calculate-signature.html) Create a signature for your request by using a cryptographic hash function that accepts two input strings: your *string to sign* and a *derived key*. The *derived key* is calculated by starting with your secret access key and using the *credential scope* string to create a series of Hash-based Message Authentication Codes (HMACs). ### Example Signature Calculation The following example walks you through the details of creating a signature for [ListGateways](https://docs.aws.amazon.com/storagegateway/latest/APIReference/API_ListGateways.html). The example could be used as a reference to check your signature calculation method. The example assumes the following: + The time stamp of the request is "Mon, 10 Sep 2012 00:00:00" GMT. + The endpoint is the US East (Ohio) region. The general request syntax (including the JSON body) is: ``` POST / HTTP/1.1 Host: storagegateway.us-east-2.amazonaws.com x-amz-Date: 20120910T000000Z Authorization: SignatureToBeCalculated Content-type: application/x-amz-json-1.1 x-amz-target: StorageGateway_20120630.ListGateways {} ``` The canonical form of the request calculated for [[Task 1: Create a Canonical Request](https://docs.aws.amazon.com/general/latest/gr/sigv4-create-canonical-request.html)](#SignatureCalculationTask1) is: ``` POST / content-type:application/x-amz-json-1.1 host:storagegateway.us-east-2.amazonaws.com x-amz-date:20120910T000000Z x-amz-target:StorageGateway_20120630.ListGateways content-type;host;x-amz-date;x-amz-target 44136fa355b3678a1146ad16f7e8649e94fb4fc21fe77e8310c060f61caaff8a ``` The last line of the canonical request is the hash of the request body. Also, note the empty third line in the canonical request. This is because there are no query parameters for this API (or any Storage Gateway APIs). The *string to sign* for [[Task 2: Create a String to Sign](https://docs.aws.amazon.com/general/latest/gr/sigv4-create-string-to-sign.html)](#SignatureCalculationTask2) is: ``` AWS4-HMAC-SHA256 20120910T000000Z 20120910/us-east-2/storagegateway/aws4_request 92c0effa6f9224ac752ca179a04cecbede3038b0959666a8160ab452c9e51b3e ``` The first line of the *string to sign* is the algorithm, the second line is the time stamp, the third line is the *credential scope*, and the last line is a hash of the canonical request from Task 1. For [[Task 3: Create a Signature](https://docs.aws.amazon.com/general/latest/gr/sigv4-calculate-signature.html)](#SignatureCalculationTask3), the *derived key* can be represented as: ``` derived key = HMAC(HMAC(HMAC(HMAC("AWS4" + YourSecretAccessKey,"20120910"),"us-east-2"),"storagegateway"),"aws4_request") ``` If the secret access key, wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY, is used, then the calculated signature is: ``` 6d4c40b8f2257534dbdca9f326f147a0a7a419b63aff349d9d9c737c9a0f4c81 ``` The final step is to construct the `Authorization` header. For the demonstration access key AKIAIOSFODNN7EXAMPLE, the header (with line breaks added for readability) is: ``` Authorization: AWS4-HMAC-SHA256 Credential=AKIAIOSFODNN7EXAMPLE/20120910/us-east-2/storagegateway/aws4_request, SignedHeaders=content-type;host;x-amz-date;x-amz-target, Signature=6d4c40b8f2257534dbdca9f326f147a0a7a419b63aff349d9d9c737c9a0f4c81 ``` ## Error Responses **Topics** + [Exceptions](#APIGeneralExceptions) + [Operation Error Codes](#APIOperationErrorCodes) + [Error Responses](#RESTErrorResponses) This section provides reference information about AWS Storage Gateway errors. These errors are represented by an error exception and an operation error code. For example, the error exception `InvalidSignatureException` is returned by any API response if there is a problem with the request signature. However, the operation error code `ActivationKeyInvalid` is returned only for the [ActivateGateway](https://docs.aws.amazon.com/storagegateway/latest/APIReference/API_ActivateGateway.html) API. Depending on the type of error, Storage Gateway may return only just an exception, or it may return both an exception and an operation error code. Examples of error responses are shown in the [Error Responses](#RESTErrorResponses). ### Exceptions The following table lists AWS Storage Gateway API exceptions. When an AWS Storage Gateway operation returns an error response, the response body contains one of these exceptions. The `InternalServerError` and `InvalidGatewayRequestException` return one of the operation error codes [Operation Error Codes](#APIOperationErrorCodes) message codes that give the specific operation error code. | Exception | Message | HTTP Status Code | | --- | --- | --- | | IncompleteSignatureException | The specified signature is incomplete. | 400 Bad Request | | InternalFailure | The request processing has failed due to some unknown error, exception or failure. | 500 Internal Server Error | | InternalServerError | One of the operation error code messages [Operation Error Codes](#APIOperationErrorCodes). | 500 Internal Server Error | | InvalidAction | The requested action or operation is invalid. | 400 Bad Request | | InvalidClientTokenId | The X.509 certificate or AWS Access Key ID provided does not exist in our records. | 403 Forbidden | | InvalidGatewayRequestException | One of the operation error code messages in [Operation Error Codes](#APIOperationErrorCodes). | 400 Bad Request | | InvalidSignatureException | The request signature we calculated does not match the signature you provided.

Check that your JSON payload is well-formed. | 400 Bad Request | | ServiceUnavailable | The request has failed due to a temporary failure of the server. | 503 Service Unavailable | | SubscriptionRequiredException | The AWS Access Key Id needs a subscription for the service. | 400 Bad Request | | ThrottlingException | Rate exceeded. | 400 Bad Request | | TooManyRequests | Too many requests. | 429 Too Many Requests | | UnknownOperationException | An unknown operation was specified. Valid operations are listed in [Storage Gateway API Actions](#AWSStorageGatewayAPIOperations). | 400 Bad Request | | UnrecognizedClientException | The security token included in the request is invalid. | 400 Bad Request | | ValidationException | The value of an input parameter is bad or out of range. | 400 Bad Request | ### Operation Error Codes The following table shows the mapping between AWS Storage Gateway operation error codes and APIs that can return the codes. All operation error codes are returned with one of two general exceptions—`InternalServerError` and `InvalidGatewayRequestException`—described in [Exceptions](#APIGeneralExceptions). | Operation Error Code | Message | Operations That Return this Error Code | | --- | --- | --- | | ActivationKeyExpired | The specified activation key has expired. |

there is an error, the response header information contains: + Content-Type: application/x-amz-json-1.1 + An appropriate `4xx` or `5xx` HTTP status code The body of an error response contains information about the error that occurred. The following sample error response shows the output syntax of response elements common to all error responses. ``` { "__type": "String", "message": "String", "error": { "errorCode": "String", "errorDetails": "String" } } ``` The following table explains the JSON error response fields shown in the preceding syntax. **\$1\$1type** One of the exceptions from [Exceptions](#APIGeneralExceptions). *Type*: String **error** Contains API-specific error details. In general errors (i.e., not specific to any API), this error information is not shown. *Type*: Collection **errorCode** One of the operation error codes . *Type*: String **errorDetails** This field is not used in the current version of the API. *Type*: String **message** One of the operation error code messages. *Type*: String #### Error Response Examples The following JSON body is returned if you use the DescribeStorediSCSIVolumes API and specify a gateway ARN request input that does not exist. ``` { "__type": "InvalidGatewayRequestException", "message": "The specified volume was not found.", "error": { "errorCode": "VolumeNotFound" } } ``` The following JSON body is returned if Storage Gateway calculates a signature that does not match the signature sent with a request. ``` {   "__type": "InvalidSignatureException",   "message": "The request signature we calculated does not match the signature you provided." } ``` ## Storage Gateway API Actions For a list of Storage Gateway operations, see [Actions](https://docs.aws.amazon.com/storagegateway/latest/APIReference/API_Operations.html) in the *AWS Storage Gateway API Reference*.
