Create Units and Modifiers in the Seller Dashboard
This is pre-release documentation for an API in public beta and is subject to change.
Measurement units and item modifiers that exist in an external system must also exist in Square so that the two systems can be mapped using the Square Bridge Integration Wizard.
Before using the Square Bridge Integration Wizard to map entities across systems, you must create any needed modifiers and units in the Square Seller Dashboard.
Follow these steps if you plan to synchronize items that have modifiers:
On the Items page, choose Modifiers (this page is also accessible at Item Modifiers).
On the Modifiers page, choose Create Modifier Set.
Enter the name of the modifier set, enter the name and price of its modifiers, and check any options as appropriate.
Choose Save when done, and then repeat modifier set creation as needed to reflect your external system.
Follow these steps if you plan to synchronize items that have a unit of measure:
Log in to the Square Seller Dashboard using the new Square account that integrates with your external system.
In the left pane, choose Items (this page can also be found at Items Library).
On the Items page, choose Units (this page is also accessible in the Seller Dashboard at Units).
On the Units page, choose Add a Unit.
Select a preexisting unit type from Square and select the appropriate precision.
Create your own custom unit by typing the name of your custom unit in the Unit field.
Repeat as needed until the units of measure in your external system are reflected in Square.
