Input validation
Checking that incoming data meets required formats and constraints before processing it. Example: verifying an email address is valid format, a phone number has the correct number of digits, and a required field is not empty before writing to a CRM.
Expert insight
Input validation that only checks a field is non-empty, not that it's in the expected format, catches only the most obvious bad data. A phone number field validated as "not empty" still lets through "asdf" or a string of the wrong length, validation needs to check shape and plausibility, not just presence.
In a real workflow
Emails, phone numbers and amounts are checked before the workflow creates records.
Common mistakes
- Validating only in the frontend.
- Rejecting data without telling anyone.
