When configuring rules inside a condition step, you choose an operator that defines how the field value is compared to the target value. This page lists every available operator, organized by category.
Comparison operators
Comparison operators evaluate a single field against a target value. These are the operators you select when adding a rule to a branch.
IN vs. IS ONE OF
Both IN and IS ONE OF check whether a value matches one of several options. The difference is in how you provide the list:
- IN — You enter a comma-separated set of values directly in the rule.
- IS ONE OF — You select from a predefined list of known values for that field (for example, a list of supported card brands or currencies).
Use IS ONE OF when the field has a known set of valid options. Use IN when you need to specify arbitrary values.
Logical operators
Logical operators control how multiple rules within a branch are combined.
AND
When rules are combined with AND, all rules in the group must be true for the branch to match.
Example: To match high-value EUR transactions, combine two rules with AND:
- Amount
> 1000 AND
- Currency =
EUR
Both conditions must be true for the branch to activate.
When rules are combined with OR, the branch matches if at least one rule in the group is true.
Example: To match transactions from any Nordic country, combine rules with OR:
- Country =
SE OR
- Country =
NO OR
- Country =
DK OR
- Country =
FI
The branch activates if the country matches any of these values.
For this particular example, using a single rule with the IN or IS ONE OF operator would be simpler: Country IN SE, NO, DK, FI.
NOT
The NOT operator negates an individual rule. When NOT is enabled on a rule, the rule matches when its comparison is not true.
Example: Amount NOT > 1000 matches transactions where the amount is 1000 or less.
You can combine NOT with any comparison operator. Enable it using the NOT toggle on the rule row in the settings panel.
Building advanced rule groups
You can combine logical and comparison operators to create sophisticated branching logic:
- Add multiple rules to a branch to test several fields at once.
- Choose AND or OR between rules using the logic toggle.
- Enable NOT on individual rules to negate specific comparisons.
Example — Route to a premium provider:
A branch named “Premium EU card” could use the following rules combined with AND:
- Card brand IS ONE OF
Visa, Mastercard
- Country IN
DE, FR, NL, BE, AT
- Amount
>= 500
All three conditions must be satisfied for the branch to match.
