session.version ASCII Text OPTIONAL

Use this field to implement optimistic locking of the session content.

To use optimistic locking, record session.version when you make your decisions, and then pass that value in session.version when you submit your request operation to the gateway.

If session.version provided by you does not match that stored against the session, the gateway will reject the operation with error.cause=INVALID_REQUEST.
