Shopify Flow connectors
Create connectors for Shopify Flow to enable your app or service to integrate with Shopify and other apps through automated workflows.
By building a connector, you can create triggers and actions that start or end workflows.
To use the triggers and actions that you create, merchants need to have your app and Shopify Flow installed.
To create triggers and actions for your merchants, you use the App Extensions platform.
Merchants can create workflows with any combination of triggers and actions from Shopify or an app that they have installed that also has connectors.
Your actions can be paired with any type of trigger in a workflow. That is, a workflow that uses your action can start with a trigger from Shopify Flow (such as Order created) or from another app partner.
Triggers that you create can be paired with other app partner actions, but not with a Shopify action (such as Add customer tags).
