Spoks's Form submission trigger only fires for Spoks's own forms. If you're using a third-party form tool like Shopify Forms, you can still trigger a Spoks flow when someone submits a form — by tagging contacts on submission and triggering a flow on the tag.
Step 1: Tag contacts who submit the form
Configure your form tool to apply a tag to anyone who submits the form. In Shopify Forms, this is done using the Add tag field in the form's settings. Use a unique tag name that's specific to this form — for example, newsletter-signup or popup-spring-promo. This makes it easy to filter on later.
Step 2: Create the flow in Spoks
In Spoks, create a new flow from scratch and configure the trigger:
Set the trigger to Tags updated.
Add a filter on the trigger: Tag includes [your tag].
The flow will run for every contact who gets tagged with that value.
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.
