Trigger overview

A trigger is a task in Shopify Flow that starts the execution of a workflow. The trigger represents an event that happens in a store or in an app. You can build a trigger for Shopify Flow so that events in your app trigger workflows to run.

• To build a trigger, you need to create a trigger extension in your app. In that extension, you specify details about the trigger using a TOML file.
• Once you have published your extension, you can then test or use it by calling the Shopify API with the trigger payload.
