Reference

Replacers reference

Every {{ template }} you can use in a flow — random data, dates, ids.

Replacers customise requests, and mimicked responses, with values generated on every run. They are Handlebars templates: write {{ randomInt0_100 }} and it becomes a different number each time the flow runs.

Dates in the past

timeAgo, timestampAgo and tsAgo take an amount and a unit (ms, seconds, minutes, hours, days, months, years):

timeAgo 5 "days"        # a Date, 5 days ago
timestampAgo 2 "hours"  # milliseconds, 2 hours ago
tsAgo 1 "month"         # YYYYMMDDHHMMSS, a month ago

Helpers

barcode(["123456", 3, "789"])   # "123456123789" — numbers add N digits
oneOf(["a", "b", "c"])          # picks one at random
