FAQ
Questions about Formstack Submission.
How does the Formstack Submission trigger work in Formstack?
Fires when someone submits a Formstack form. Identical shape to the formio variant — both connector instances expose the same Formstack trigger.
Is the Formstack Submission trigger real-time?

What data does Formstack Submission return?
The full event payload from Formstack. The output shape table on this page lists every field, its type, and an example value so you can map fields into downstream nodes.
Can I filter Formstack Submission so only some events start a workflow?
Yes. Add a Filter node right after the trigger and match on any field, whether that's subject, sender, status, or anything else in the payload. Workflows only continue when the filter passes.
Do I need Formstack admin permissions to use Formstack Submission?
For most Formstack accounts a standard user can authorize the trigger. Some Formstack plans require an admin to enable third-party webhooks. Check Formstack's docs if the trigger fails to register.
