Carrd form webhook firing Make scenario but users getting JavaScript error on submission

:bullseye: What is your goal?

Enable successful submission of sign up form on Carrd and creation of subscriber in Beehiiv

:thinking: What is the problem & what have you tried?

I have a Carrd landing page with a native form
configured to send to a Make.com custom webhook.
The webhook triggers a Beehiiv Create Subscriber
module.

The scenario works correctly when tested manually
via Run Once. However Clarity session recordings
show live users filling out the form and clicking
submit but receiving this error:

“Sorry, something went wrong. Please try again later.”

The submission fails and no subscriber is created
in Beehiiv.

My setup:

  • Carrd native form → Make.com custom webhook
  • Make.com → Beehiiv Create Subscriber module
  • Scenario is ON and set to run immediately
  • Double opt-in enabled in Beehiiv

The scenario execution history shows no runs
during the periods when Clarity shows failed
submissions — suggesting the webhook is not
receiving the data at all despite the form
appearing to submit.
Has anyone seen this pattern before? Is there
a Carrd/Make webhook reliability issue under
live traffic that differs from manual testing?

Hello,

I understand this could simply be an unintentional mistake, but to use Carrd Forms with Make, you need to be on the Pro Plus plan and use Custom Forms.
You mentioned that you are using a sign-up form, and that type of form cannot be connected to a webhook.

Also, there is no magic behind it- you can copy the webhook URL and trigger it directly from your browser. If the scenario works that way (you can see a successful run in your history), then the issue is most likely in the Carrd configuration or in an incorrectly pasted webhook URL.

Thank you — this was the most critical piece of feedback. Confirmed we are on
Pro Plus and using a Custom form type, so the plan requirement is met. Your
point about signup forms not supporting webhooks is something others will likely
run into with this setup. Appreciated.

Resolution: Setup was correctly configured on Pro Plus with Custom form type. Added
an email filter between webhook and Beehiiv module to prevent incomplete submissions
from generating errors. IT review confirmed scenario configuration was correct. Monitoring for recurrence.
