AWS Organizations API Reference
API Reference (API Version 2016-11-28)


Declines a handshake request. This sets the handshake state to DECLINED and effectively deactivates the request.

This operation can be called only from the account that received the handshake. The originator of the handshake can use CancelHandshake instead. The originator can't reactivate a declined request, but can re-initiate the process with a new handshake request.

After you decline a handshake, it continues to appear in the results of relevant APIs for only 30 days. After that it is deleted.

Request Syntax

{ "HandshakeId": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.


The unique identifier (ID) of the handshake that you want to decline. You can get the ID from the ListHandshakesForAccount operation.

The regex pattern for handshake ID string requires "h-" followed by from 8 to 32 lower-case letters or digits.

Type: String

Pattern: ^h-[0-9a-z]{8,32}$

Required: Yes

Response Syntax

{ "Handshake": { "Action": "string", "Arn": "string", "ExpirationTimestamp": number, "Id": "string", "Parties": [ { "Id": "string", "Type": "string" } ], "RequestedTimestamp": number, "Resources": [ { "Resources": [ "HandshakeResource" ], "Type": "string", "Value": "string" } ], "State": "string" } }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

For information about the errors that are common to all actions, see Common Errors.


You don't have permissions to perform the requested operation. The user or role that is making the request must have at least one IAM permissions policy attached that grants the required permissions. For more information, see Access Management in the IAM User Guide.

HTTP Status Code: 400


The target of the operation is currently being modified by a different request. Try again later.

HTTP Status Code: 400


The specified handshake is already in the requested state. For example, you can't accept a handshake that was already accepted.

HTTP Status Code: 400


We can't find a handshake with the HandshakeId that you specified.

HTTP Status Code: 400


You can't perform the operation on the handshake in its current state. For example, you can't cancel a handshake that was already accepted, or accept a handshake that was already declined.

HTTP Status Code: 400


The requested operation failed because you provided invalid values for one or more of the request parameters. This exception includes a reason that contains additional information about the violated limit:


Some of the reasons in the following list might not be applicable to this specific API or operation:

  • INVALID_PARTY_TYPE_TARGET: You specified the wrong type of entity (account, organization, or email) as a party.

  • INVALID_SYNTAX_ORGANIZATION_ARN: You specified an invalid ARN for the organization.

  • INVALID_SYNTAX_POLICY_ID: You specified an invalid policy ID.

  • INVALID_ENUM: You specified a value that is not valid for that parameter.

  • INVALID_FULL_NAME_TARGET: You specified a full name that contains invalid characters.

  • INVALID_LIST_MEMBER: You provided a list to a parameter that contains at least one invalid value.

  • MAX_LENGTH_EXCEEDED: You provided a string parameter that is longer than allowed.

  • MAX_VALUE_EXCEEDED: You provided a numeric parameter that has a larger value than allowed.

  • MIN_LENGTH_EXCEEDED: You provided a string parameter that is shorter than allowed.

  • MIN_VALUE_EXCEEDED: You provided a numeric parameter that has a smaller value than allowed.

  • IMMUTABLE_POLICY: You specified a policy that is managed by AWS and cannot be modified.

  • INVALID_PATTERN: You provided a value that doesn't match the required pattern.

  • INVALID_PATTERN_TARGET_ID: You specified a policy target ID that doesn't match the required pattern.

  • INPUT_REQUIRED: You must include a value for all required parameters.

  • INVALID_PAGINATION_TOKEN: Get the value for the NextToken parameter from the response to a previous call of the operation.

  • MAX_FILTER_LIMIT_EXCEEDED: You can specify only one filter parameter for the operation.

HTTP Status Code: 400


AWS Organizations can't complete your request because of an internal service error. Try again later.

HTTP Status Code: 400


You've sent too many requests in too short a period of time. The limit helps protect against denial-of-service attacks. Try again later.

HTTP Status Code: 400
