Rules explained
- Address validation (require house number): checks if a street number exists.
- Check names (first and last name must differ): catches duplicate names.
- Block special characters in address: flags unusual symbols.
- Check email typos: catches common domain typos.
- Block address with custom regex: blocks patterns you define.
- Length limits: restricts max characters for address fields, names, and company.
For many rules, you can choose:
- Show warning only
- Block checkout
If you are new, start with warnings first, then move to blocking rules after testing.
FAQ
What is the most important in-checkout rule?
Most merchants start with require house number because it prevents common delivery failures.
Can I activate only some in-checkout rules?
Yes, you can enable only the rules you need and leave others off.
It is safer to start with warnings, validate behavior, and then block critical rules.
