Power Automate (WDL) function

or — Power Automate (WDL) function reference

Any condition true.

Syntax

wdl

or(expression1, expression2, ...)

wdl

or(equals(s, 'A'), equals(s, 'B'))

→ true / false

wdl

or(equals(item()?['Priority'], 'High'), equals(item()?['Priority'], 'Critical'))

→ true / false

wdl

or(empty(item()?['Email']), empty(item()?['Phone']))

→ true / false

Like and(), or() is variadic and accepts more than two conditions in a single call.
WDL doesn't document short-circuit evaluation for or()/and() — don't rely on a later argument never being evaluated to dodge an error in it; guard risky sub-expressions independently.
