# Delete a buy instruction

Retires a buy instruction you no longer intend to use, so a fiat payment arriving later with
its memo can never mint against it. Because instructions never expire, this is the only way
to retire an unused one - an abandoned instruction left alone stays UNUSED and claimable
indefinitely.

Deletion is permanent and there is no un-delete: create a new instruction with a new id,
which gets a new memo. Transactions already produced from the instruction are unaffected and
keep their fiatInstructionId and memo.

Only your own UNUSED buy instructions can be deleted. A redemption (FIAT) instruction is
reported as 404, since this operation only addresses your CRYPTO instructions.
