You can automatically run a flow for people who submit a form by using the Form submission trigger.
This article covers Spoks forms specifically. If you're using a third-party form tool like Shopify Forms, see How do I trigger a flow from a third-party form submission? instead.
Step 1: Create a flow in Spoks
In Spoks, create a new flow from scratch and set the trigger to Form submission.
Step 2: Filter the trigger to a specific form
By default, the trigger fires for any form submission. To run the flow only for a specific form, add a trigger filter that scopes the trigger to the form you want.
Step 3: Configure what the flow does
From here, the flow works like any other Spoks flow. Add whatever actions you want to run for people who submit the form.
