# Effectuate a MED refund debit

> Effectuates the refund DEBIT at SPI for an accepted refund: posts a balanced PENDING Midaz double-entry (contestado debit, clearing credit) and generates the pacs.004. The debit commits on the settlement reconcile poll. The precondition (accepted AND not-yet-effectuated) is checked before any ledger touch; a non-accepted or already-effectuated request returns a coded 422 and a re-delivery is an idempotent no-double-post echo. An unknown id returns a coded 404.
