time stamps info on form submissions

[isabelsteffi]

Hi, I am looking for a solution to track the timestamp of when the invitee filled up the form as i am working on an event that allows only the first 12 members who filled the form. please share your suggestions! Thanks, Isabel

In the past, I've used a Program Member Custom Field (PMCF) for this and then created a smart campaign that uses the {{system.dateTime}} token to drop in the value for when the form was submitted.

If you set the smart campaign only to allow a person to run through it once, you prevent multiple submissions from overwriting the field. 

One minus of this approach is if you're trying to use this on a global form, as PMCFs are only supported in local forms. And, of course, the limits on PMCFs in general. But, if you have some to spare and are using a local form, this is one approach.

I would say this is a pretty iffy way to limit members. Hopefully you have wording on the form that makes it clear that they may be rejected. Much better would be using a solution to actually limit registrants.

Sanford can't share this link because he created Flowboost but I'm gonna go ahead and post it because I'm pretty sure it's the only purpose-built solution for this (see the user guide)

Indeed! Though one might build another solution that would work as well, there's pretty much one direct way to skin this cat. (Read/write a shared counter via webhook.)
