AWS Organizations
API Reference


Sends an invitation to another account to join your organization as a member account. AWS Organizations sends email on your behalf to the email address that is associated with the other account's owner. The invitation is implemented as a Handshake whose details are in the response.


  • You can invite AWS accounts only from the same seller as the master account. For example, if your organization's master account was created by Amazon Internet Services Pvt. Ltd (AISPL), an AWS seller in India, you can invite only other AISPL accounts to your organization. You can't combine accounts from AISPL and AWS or from any other AWS seller. For more information, see Consolidated Billing in India.

  • If you receive an exception that indicates that you exceeded your account limits for the organization or that the operation failed because your organization is still initializing, wait one hour and then try again. If the error persists after an hour, contact AWS Support.

This operation can be called only from the organization's master account.

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


You can't invite an existing account to your organization until you verify that you own the email address associated with the master account. For more information, see Email Address Verification in the AWS Organizations User Guide.

HTTP Status Code: 400


Your account isn't a member of an organization. To make this request, you must use the credentials of an account that belongs to an organization.

HTTP Status Code: 400


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

HTTP Status Code: 400


A handshake with the same action and target already exists. For example, if you invited an account to join your organization, the invited account might already have a pending invitation from this organization. If you intend to resend an invitation to an account, ensure that existing handshakes that might be considered duplicates are canceled or declined.

HTTP Status Code: 400


AWS Organizations couldn't perform the operation because your organization hasn't finished initializing. This can take up to an hour. Try again later. If after one hour you continue to receive this error, contact AWS Support.

HTTP Status Code: 400


The requested operation would violate the constraint identified in the reason code.


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

  • ACCOUNT_NUMBER_LIMIT_EXCEEDED: You attempted to exceed the limit on the number of accounts in an organization. Note that deleted and closed accounts still count toward your limit.


    If you get this exception immediately after creating the organization, wait one hour and try again. If after an hour it continues to fail with this error, contact AWS Support.

  • ALREADY_IN_AN_ORGANIZATION: The handshake request is invalid because the invited account is already a member of an organization.

  • HANDSHAKE_RATE_LIMIT_EXCEEDED: You attempted to exceed the number of handshakes that you can send in one day.

  • INVITE_DISABLED_DURING_ENABLE_ALL_FEATURES: You can't issue new invitations to join an organization while it's in the process of enabling all features. You can resume inviting accounts after you finalize the process when all accounts have agreed to the change.

  • ORGANIZATION_ALREADY_HAS_ALL_FEATURES: The handshake request is invalid because the organization has already enabled all features.

  • ORGANIZATION_FROM_DIFFERENT_SELLER_OF_RECORD: The request failed because the account is from a different marketplace than the accounts in the organization. For example, accounts with India addresses must be associated with the AISPL marketplace. All accounts in an organization must be from the same marketplace.

  • ORGANIZATION_MEMBERSHIP_CHANGE_RATE_LIMIT_EXCEEDED: You attempted to change the membership of an account too quickly after its previous change.

  • PAYMENT_INSTRUMENT_REQUIRED: You can't complete the operation with an account that doesn't have a payment instrument, such as a credit card, associated with it.

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:

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

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

  • INVALID_ENUM: You specified an invalid value.

  • 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.

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

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

  • 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.

  • INVALID_ROLE_NAME: You provided a role name that isn't valid. A role name can't begin with the reserved prefix AWSServiceRoleFor.

  • INVALID_SYNTAX_ORGANIZATION_ARN: You specified an invalid Amazon Resource Name (ARN) for the organization.

  • INVALID_SYNTAX_POLICY_ID: You specified an invalid policy ID.

  • INVALID_SYSTEM_TAGS_PARAMETER: You specified a tag key that is a system tag. You can’t add, edit, or delete system tag keys because they're reserved for AWS use. System tags don’t count against your tags per resource limit.

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

  • 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.

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