Billing by batch size
For API flows, billing is based on how many entries are actually included in a mailing batch. The trigger window only decides when a batch is formed. If you do not have enough credit, the batch is not sent; the configuration remains in place and PostPal notifies you.
API flows are billed by the actual batch size. The relevant number is how many entries are really included in a mailing.
The trigger window only controls when PostPal forms a batch. It is not the basis for billing.
If your credit is not sufficient for a batch, it is not sent. The flow remains in place, and open entries can be processed again during a later run.
