If a premium MT message cannot be delivered due to billing reasons (for example, end user out of credit), the MX Telecom SMS Gateway will normally resubmit the message to the carrier at regular intervals, up to the expiry time of the message. This increases revenue by improving delivery success rates.
However, to enable partners to have more control over premium billing, this behaviour can be disabled on a per-message or per-account basis. This behaviour is known as single-shot billing.
Enabling single-shot billing
On a per-message basis
Individual messages can be marked as single-shot billed via additional parameters in the message-sending interfaces.
- HTTP interface: using the billingsingleshot parameter. See the HTTP API Reference for more details.
- For other interfaces, please contact us for more details.
On a per-account basis
- Please contact us to have single-shot billing enabled on all messages through one or more of your SMS Gateway accounts.
Single-shot billing is only supported on carriers where MX Telecom has control of the billing process. These are shown in the table below. Click here for a table of carrier codes.
On most other carriers, the message is held by the carrier until it can be billed, or until it expires.
