Routing rules
Rules are where a routing form does its job: each rule has conditions on the form's answers and a destination. When someone submits the form, 42min checks the rules from top to bottom and uses the first one whose conditions match — so order matters. You edit them on the form's Rules tab (open the builder).
How a rule works
- Conditions — one or more checks against the visitor's answers, combined with AND ("all of these must be true") or OR ("any of these"). A check looks at a field and tests its value — for example "Team size" is "200+", or "Region" is one of "EU", "UK". (The exact set of operators — equals, is one of, contains, and so on — is shown in the rule editor; pick what fits the field type.)
- Destination — where matching people go: an event type's booking page, an external URL, a custom message, or another routing form. See Destinations.
Order and the fallback
- Rules are evaluated top to bottom; the first match wins. Put your most specific rules first and broader ones below — otherwise a broad rule grabs everyone before a narrow one gets a look.
- The last rule is the fallback — it's mandatory and has no conditions; it catches everyone who matched nothing above. Make it a sensible default (commonly your general intro-call event type or a "we'll be in touch" message), so no one ever hits a dead end.
How to do it
- On the form's Rules tab, add a rule. Build its conditions (choose a field, an operator, a value; add more and pick AND / OR).
- Set the rule's destination.
- Add more rules, dragging them into priority order — narrowest at the top.
- Configure the fallback rule's destination.
- Save, then submit the form yourself a few times with different answers to confirm each path lands where you expect. The form's Responses tab shows which rule each submission matched.
Common pitfalls
- Broad rule above a narrow one. "Team size is anything → intro call" placed above "Team size is 200+ → enterprise rep" means no one reaches the enterprise rep — the broad rule matches first. Reorder so specific beats general.
- Forgot the fallback (or made it useless). Every form must have one; a person who matches nothing else ends up there. An empty or broken fallback is a dead end.
- AND where you meant OR. "Region is EU AND Region is UK" can never be true — for "either of these values", use OR (or an "is one of" condition).
