SMS variables

Each SMS type supports a specific set of variables. The info icon shows the variables supported for that specific SMS type.

VariableDescription
{{link}}The URL to the signing or payment page
{{number}}Invoice number
{{duedate}}Date the invoice is due
{{amount}}Payment amount
{{name}}Your company name
One SMS message consists of 160 characters. If your text exceeds this limit, a warning '> 1 sms' is displayed, meaning the message will be sent (and billed) as multiple text messages. Keep this in mind when using variables, since these are converted to their actual value before the message is sent and may add more characters than expected.
