Has the behavior of the sandbox changed? We have tests calling https://www.testvantivcnp.com/sandbox/communicator/online that were working that have suddenly started to fail. RegisterToken requests that are passed an order id are no longer returning it. We were processing an echeck sales request with account number 123456 and routing number 322172797. Previously it was returning a partial approval and now it is returning "Approved".
Hi,
The sandbox has been updated with new features and bug fixes so that it can respond with accurate messages based on the request. Features are available here: Developers | Vantiv
You can try sending the request and response xml to sdksupport@vantiv.com and we can take a look further to see what's going on with your request.
Thanks,
Swapnil
