Tiny keeps the child record as the source of truth, then uses narrow data paths for account access, subscription billing, account email, 837P submissions, acknowledgments, and payment returns.
Some systems expose an online connection. EI Hub work still relies on controlled file exchange, so Tiny Solutions treats the file, status, and return record as one traceable handoff.
Tiny Solutions does not pretend that a portal upload is a live online connection. The product keeps the submission and return evidence together so staff can see what happened next.
Tiny Solutions does not currently publish general API credentials or promise an online connection that the product does not provide. Agency exports and the documented handoffs remain the dependable route today.
