Pebble Template Syntax

All input fields in the Flow Designer use an open-source expression syntax called Pebble Templates: https://pebbletemplates.io/.

The following are supported symbols in Pebble Templates: ==, !=, <, >, <=, >=, +, -, *, / . To type custom variables in an expression, use this syntax: {{variable}}

Logic operators are also supported. For more information, see https://pebbletemplates.io/wiki/operator/logic/.

We recommend that you review the Pebble Template documentation before you use expressions in Flow Designer. For information on writing expressions, see the documents at: https://pebbletemplates.io/wiki/.

For example, in this basic condition use case, the expression checks to see if the caller’s AccountNumber is greater than or equal to a certain value. Based on how the expression evaluates for a given flow execution, the flow can take the True or the False path.
