# Automatically Calculated Context Vars

### Automatically Calculated Context Vars
When the Peach system sends messages it automatically calculates context variables.
These context variables can be referenced in the template content. For example, when the system
sends `autopayEnabled` it includes the populated context variables `paymentMethod`, `paymentMethodLastFour`,
and `paymentSchedule`.
