Creating a "counter" field for form submissions for noting max capacity

I am trying to get an alert for when a particular form is submitted a certain number of times. Ex: after 10 form submissions I know to take the form down as we would have reached max capacity for an event initiative.

Essentially, I'm trying to think through if there is a new custom field that could be created that would incrementally update when a new form submission comes in, then when it reaches the max total, a flow is triggered.

You can’t do this using built-in features. A webhook-compatible service can do it quite easily.

Hi @samanthawi3 Marketo doesn't have a built-in feature for this, and it can't be achieved using just JavaScript, as JS will execute from scratch with every form submission. To implement this functionality, you'll need to use a webhook or API integration, since there's no way to prevent users from submitting the form within Marketo.

Thanks!!

    Step 1: Create a Custom Field
    Create a new Form Fill Score field in your lead database. This field will act as a counter, incrementing with each submission of your specific form.

     

    Step 2: Smart Campaign to Increment the Score
    Set up a Smart Campaign with the trigger:

    • Fills Out Form with the constraint Form is [Your Form Name]

    In the Flow:

    • Change Data Value > Attribute: Form Fill Score > New Value:  + 1

     

    Step 3: Smart Campaign to Trigger the Alert
    Create another Smart Campaign with:

    • Form Fill Score equals 10 (or whatever your threshold is)

    Flow:

    • Send Alert to your internal team
    • Optional: Add a flow step to pause or notify someone to manually remove the form

    If you’re running multiple events, it’s easy for this to get messy. Be methodical in how you name your fields (e.g., Form Fill Score – Webinar A) or consider using a more scalable approach like a custom object if your use case grows.

    This method is simple but effective, especially when you just need a lightweight way to monitor capacity for events or gated offers.

    This looks like an AI fantasy to me.

     

    "Form Fill Score" as a lead field would add +1 for one form submit from one person. It won't count overall form submits.

      @michael_florin-2 Thanks for the input. The original question was about event capacity, not necessarily form submissions. I was merely trying to help out. It may not be the best option, but I've done this for other organizations when they have event capacity and need to turn off the form after a certain number of people register.
