A merchant does not obtain authorization for a $30 transaction but sends the clearing message anyway. Galileo is obligated to post all settlements, even if they do not have a matching authorization. This is similar to the transaction shown in <a href="doc:card-transaction-examples#settlement-of-an-expired-authorization" target="_blank">Settlement of an Expired Authorization</a> in _Card Transaction Examples_.
To simulate a force-post, do not create an authorization first and then expire it. In <<glossary:CV>>, you simulate a settlement, and then the simulator creates and backs out an authorization before posting the settlement. This type of transaction is a true force-post, which is transaction type (otype) `
M`. Also see:
