TriggerKit (ConvertKit)Real-timeUpdated June 2026

When does Kit fire on form subscribers?

Short answer: In TinyCommand, add the Kit (ConvertKit) Form Subscribed trigger to a workflow and publish. It listens through a Kit (ConvertKit) webhook and fires your workflow within seconds of the event, with no polling and no code. Add a filter if you only want some events to start a run.

FAQ

Questions about Form Subscribed.

How does the Form Subscribed trigger work in Kit (ConvertKit)?
Fires when a new subscriber confirms opt-in via a specific Kit form (after double-opt-in completes if enabled). Payload includes the subscriber with custom fields and the form they subscribed via. Scope to a single form ID at trigger setup.
Is the Form Subscribed trigger real-time?
Yes. Form Subscribed uses webhooks or push subscriptions, not polling. Your workflow fires within seconds of the event happening in Kit (ConvertKit).
What data does Form Subscribed return?
The full event payload from Kit (ConvertKit). 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 Form Subscribed 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 Kit (ConvertKit) admin permissions to use Form Subscribed?
For most Kit (ConvertKit) accounts a standard user can authorize the trigger. Some Kit (ConvertKit) plans require an admin to enable third-party webhooks. Check Kit (ConvertKit)'s docs if the trigger fails to register.
