FAQ
Shopify Flow Apps FAQ
Common questions about Shopify Flow & Automation App Development with Final Apps.
What is Shopify Flow?
Shopify Flow is Shopify's automation tool. Workflows run when a trigger happens, check conditions and then perform actions, such as tagging an order or sending a notification.
Can you build custom Shopify Flow actions and triggers?
Yes. Apps can add their own triggers and actions to Flow. Our app FlowSend adds a Flow action that sends emails through your own SMTP provider.
What can I automate on Shopify?
Common automations include order tagging and routing, fraud holds, low-stock alerts, customer segmentation, internal notifications and syncing data with other systems. Our Shopify automation playbook lists 10 workflows to start with.
Is Shopify Flow free?
Shopify Flow is available on many Shopify plans at no extra cost. Check Shopify's current plan details for your store.
When do I need a custom automation app instead of Flow?
When you need actions Flow doesn't offer, connections to systems without a Flow connector, heavy bulk processing or custom interfaces. We often combine Flow with a custom app.
