How do I set up a Zap to update Shopify inventory from Square orders?

Hi there,


I am new to Zapier and am trying to integrate our square account with shopify so that when we receive an order in Square, our inventory is updated in Shopify. My issue is, I don’t understand the fields in the “Action” set-up. Specifically, do I use Line Item quantity for “adjust quantity by” and what do I use for “set quantity to”? 


Maybe someone who has set this up before can help?

Both fields expect a positive or negative number as indicated by the fields descriptions. (make sure to click [more])


Adjust Qty By

Increment the Qty up or down by a designated amount.


Set Qty To

Set the Qty to a designated amount.


Is there a how to video that i can access?

Most automations are unique so there likely won’t be video to view for help.


If you’re looking for help, consider hiring a Certified Zapier Expert:

yeah… thanks. I think I need more basic help than that. I don’t know what an array is and the descriptions below don’t seem intuitive to me, as someone not in tech. Is there a how to video that i can access? Also, I need another app to do this (what seems like a) simple function?

As mentioned, I’d like to set Zapier up so that when we get an order from Square, it is reflected in our inventory on Shopify.

Hi @MaggeCr1 

Good question.

Check the description underneath each field.

NOTE: The mapped variable for Line Items Quantity is an array.

If you want to handle each value from the array, then you can use the Looping app:
