updateToken

An optional token that you can use for optimistic locking. Firewall Manager returns a token to your requests that access the resource set. The token marks the state of the resource set resource at the time of the request. Update tokens are not allowed when creating a resource set. After creation, each subsequent update call to the resource set requires the update token.

To make an unconditional change to the resource set, omit the token in your update request. Without the token, Firewall Manager performs your updates regardless of whether the resource set has changed since you last retrieved it.

To make a conditional change to the resource set, provide the token in your update request. Firewall Manager uses the token to ensure that the resource set hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException. If this happens, retrieve the resource set again to get a current copy of it with a new token. Reapply your changes as needed, then try the operation again using the new token.
