When sending an invoice to a customer’s mobile device, there are two available methods, determined by the value set in the TransmissionMethod field:1.
M (Mobile only):The invoice will be sent to the recipient via Viber. If the recipient does not have Viber, a fallback SMS will be sent after a short period.
2.
C (Email + Mobile): The invoice will be sent to both the customer’s email and Viber. If Viber is not available, a fallback SMS will be sent instead.
To enable invoice delivery via Viber/SMS, you must populate the "CustomerCellNumbers" field with the customer’s mobile number.💡
Supported Phone Number Format:
Phone numbers must be in international format.
Greek numbers should start with +30 or 69, followed by the 10-digit mobile number (e.g., +30
6912345678).
Landline numbers are not supported for SMS and Viber messaging.
Do not include spaces, dashes, or special characters (e.g., +306912345678 is correct, while +30-691-234-5678 is incorrect).
Important Note 1: When sending an invoice to a mobile device, attachments are not supported.
Important Note 2: SMS and Viber messaging are only supported within Greece (SMS messaging
will soon be supported for international numbers, while Viber messaging will be available in both
Greece and Cyprus)
Note: When sending an invoice to a mobile device, attachments are not supported.
