MeF Resiliency Update for MeF ATS With the Filing Season 2022 R10.5 release we are introducing new functionality: In the event of major outages, the portal component of the testing system will be able to accept submissions in a limited capacity. Only Login, Logout and Send Submissions services will be active. All other services will be unavailable during outages. The testing system will be able to return receipts for submissions. A2A Transmitters will see some changes with two new fields (Deposit ID and Receipt ID) as part of Send Submissions Response. Deposit ID is a message level field and Receipt ID is a submission level field; both fields are defined as alphanumeric 80 characters. We recommend that transmitters save these new fields to their system. There is a possibility of multiple acknowledgements for a single submission. Only one acknowledgement will be primary. All other acknowledgements will be secondary and result in a duplicate error. States and IFA users will not be impacted by this change.
