How can I sync Square Product Library with Webflow Products?

Hi @KanaJapan, welcome to the Community! 🎉 

Trigger: Item?
Test: How can I configure this part?

It looks as though you’ve correctly configured the New Catalog Item (Square) trigger step as you’ve been able to load a test record - nice work on that! 🙌

Update Item in Webflow 
How can I configure Action??

In order to add the item that was created in Square in Webflow as well I expect you’d need a Create Item (Webflow) action instead of an “Update Item” action which would be used to update existing items. To set up the Create Item action you’d need to map (select) the relevant fields from the Square trigger step. You can learn more about how to set up action steps here: Set up your Zap action

That would take care of adding the new products from Square into Webflow.

In order to update the inventory, based on the other Community post you shared a link to it seems to suggest that you’d need to use the following trigger and action steps:

• Trigger: New Order (Square)
• Action: Update Item (Webflow)

However, as you’re wanting to update the inventory for multiple products this approach would likely also require the use of a “Find Item” action and a Looping by Zapier (in order to run a “Find Item” and Update Item action multiple items - once for each product ordered). The reason a “Find Item” action would be needed is to obtain the ID for the item to be updated, so that the Update Item action knows which item to update.

Unfortunately I can’t see any such “Find Item” action available for the Webflow app on Zapier. But I did find an existing feature request for one to be added so I’ve added your vote to that. I can’t make any promises around when that might be added but we’ll be sure to email you as soon as it is! 

In the meantime, perhaps you could keep a record of all the WebFlow products and their IDs in Zapier Tables - like a lookup table. That would potentially allow you to have a database of the products and their corresponding ID numbers which you could then search using a Find Records (Output as Line Items) (Zapier Tables) action to obtain the ID relevant number that the Update Item action would need to reference in the Item field. See Add custom values to dropdown menu fields in Zaps to learn more about how to reference items by ID using the Custom value option.

Hope that helps to get you pointed in the right direction. If you run into any issues on that or have further questions at all just let us know!
