We were wondering if Cognito Forms would support validation of a unique code against a database. The database of codes can be anywhere from 10,0000 to 50,000. The form would need to prevent submission when an invalid code is used.
Best Answer
Cognito Forms does not currently support database lookups. However, we are actively working on a feature called Dynamic Webhooks that would provide this exact functionality. You would still have to maintain the database of codes yourself (possibly just a Google spreadsheet) but would be able to have the form perform custom validation of codes against this database using a very simple RESTful JSON endpoint.
Please comment and upvote this feature if it is something you are interested in!
