Function reference

Function	Signature	Meaning
all	list.all(x, condition) -> bool	Check if all elements in a list satisfy the condition
contains	contains(text: string, substring: string) -> bool	Case-insensitive check if text contains the substring
containsEntryInFile	containsEntryInFile(text: string, fileUuid: string) -> bool | list	Check if text contains any entry from the specified file. Returns matched entries or false.
days_since	days_since(date: string) -> number	Calculate the number of days between an ISO date string and today in the workspace timezone
endsWith	string.endsWith(suffix: string) -> bool	Check if string ends with the given suffix
exists	list.exists(x, condition) -> bool	Check if any element in a list satisfies the condition
filter	list.filter(x, condition) -> list	Return elements that satisfy the condition
has	has(field) -> bool	Check if a field exists and is set (not null/empty)
int	int(value) -> int	Convert a value to an integer
lowerAscii	lowerAscii(text: string) -> string	Convert text to lowercase
map	list.map(x, expression) -> list	Transform each element in a list
matches	matches(text: string, pattern: string) -> bool	Check if text matches the given regex pattern
member_in_filter	member_in_filter(memberFilterUuid: string) -> bool	True when this member is in the given member filter. The argument must be a literal member-filter UUID, which is what lets the Journey preload the filter once per evaluation and refuse to delete a filter a live Journey still uses. Use the structured member-filter picker for a single filter; this is for combining several, e.g. filter A or B.
notcontains	notcontains(text: string, substring: string) -> bool	Case-insensitive check if text does NOT contain the substring
size	size(value) -> int	Return the length of a string, list, or map
split	split(text: string, delimiter: string) -> list	Split text on a delimiter
startsWith	string.startsWith(prefix: string) -> bool	Check if string starts with the given prefix
string	string(value) -> string	Convert a value to a string
trim	trim(text: string) -> string	Remove leading and trailing whitespace
type	type(value) -> type	Return the type of a value
upperAscii	upperAscii(text: string) -> string	Convert text to uppercase
us_state_to_tz	us_state_to_tz(state: string) -> string	Convert a single-zone US state or territory to a canonical IANA timezone (e.g. 'WA' / 'Washington' -> 'America/Los_Angeles', 'AZ' / 'Arizona' -> 'America/Phoenix'). Accepts USPS codes and full names, case-insensitively. Returns an empty string when the input is empty, not a US state, or a split jurisdiction — mapped onto member.timezone, an empty result leaves the existing value unchanged rather than clearing it. Prefer us_zip_to_tz when a ZIP is present; use this as a fallback.
us_zip_to_tz	us_zip_to_tz(zip: string) -> string	Convert a US ZIP code to a canonical IANA timezone (e.g. '07001' -> 'America/New_York'). Accepts ZIP+4. Returns an empty string when the ZIP is unrecognised or spans two timezones — mapped onto member.timezone, an empty result leaves the existing value unchanged rather than clearing it.
window_days_since	window_days_since(date: string) -> number	Calendar days crossed since a timestamp, counted as local DATES in this Journey's active-hours timezone (its workspace timezone when the Journey has no active hours). Unlike days_since, it does not keep the previous step's time of day: a step accepted on Monday afternoon satisfies >= 1 from Tuesday's local midnight. Active hours still decide when the step may run.
