Validation Rules

Article summary

What are validation rules?

Validation rules are records checks that help you prevent customers and admins from creating or editing a record if a condition isn't met.

For example, you want to make sure all customers have a VAT number on record. Another example would be preventing customers from booking a resource if they didn't purchase a specific product.

You can set up validation rules for the following record types:

  • Bookings 
  • Contracts 
  • Customers 
  • Invoices
  • Product sales 
  • Proposal contracts
  • Teams
  • Visitors
  • Event attendees

Validation rules apply to records your create or update on the Admin Panel, the Members Portal, the Nexudus companion apps, the Imports page, and the API.
Validation rules you create in a Network location automatically apply to all other locations within the network.

How validation rules work

Validation rules rely on a formula that assesses if a condition you define is met before creating or updating a record. The formula is simply what you tell Nexudus to check whenever a customer or an admin tries to edit a record.
