Liquid support in Flow

Developers who are experienced with Shopify Liquid can add Liquid to text fields in actions. If you aren't familiar with Shopify Liquid, then use the Add template variables window to add Liquid to your messages.

Flow supports most of Shopify Liquid, but there are some exceptions that are described here.

Conditional and iteration tags

You can manually add Liquid variable tags to your workflow messages. You can use these tags to include more information in your messages.

For example, you can use a for loop object to iterate through a list of objects, such as line items for an order. With these tags, you can create messages that contain details, such as the product title, SKU, price, and quantity for each line item in an order, and save your recipients from having to look up this information in your Shopify admin.

Flow supports all Shopify Liquid conditional (or control flow) tags:

• if
• unless
• else/elsif
• case/when
• and/or (multiple conditions)

Flow also supports all Shopify Liquid iteration tags:

• for
• cycle
• tablerow
