Formulas

A Formula is a Designer Element that allows for different computations in a mathematical format, similar to what is possible in Excel. Formulas have a dedicated Designer where they can be created and edited. After being saved a Formula can be used in a Flow through the Run Formula Step, or can be integrated into a Merge Text Field.

This feature eliminates the need to create complex Flows with mathematical steps to achieve business goals. Instead Formulas can be created and added into Flows via the Run Formula Step, or added into Rules.

Formula Designer is only available in v9.3+.
