You must ensure that this option is enabled on your acquirers

An Authorisation Only transaction gives an authorisation code for a
specific amount against a customer’s card without the capture of the
transaction details by the acquirer.
This facility is intended for merchants who wish to bank transactions
using a different system, or to check that the customer has enough
credit for a transaction.
The transaction does NOT debit the customers bank account or credit
your merchant account. The transaction value is NOT added to the
terminal totals. When an Authorisation Only transaction is done the
available credit on the customers bank account will be reduced by the
amount authorised.
Authorisation Only transactions may be submitted to the acquirer
through the Forced Transaction function. These transactions do not
include gratuities.
To perform an Authorisation Only transaction press the menu key twice,
then choose AUTH by pressing the F2 key.

Authorisation Only receipts carry the extra text of AUTHORISATION ONLY
to indicate that the transaction details are not captured by the acquirer.
Authorisation codes typically expire after 7 days (or 3-4 days for
Maestro cards). If the transaction is not submitted within that
time the customer’s available balance will be restored by the
authorised amount.
