To apply a customer tag, you can use the "Add customer tags" action in Shopify Flow, as mentioned in the actions.json document. This action allows you to add one or more tags to a customer.

You can find this action in the actions.json document, which describes the available actions in Shopify Flow. The "Add customer tags" action is also triggered by the "Customer created" trigger, as mentioned in the triggers.json document.

Additionally, you can use the "Add customer tags for all ordered product tags" template, as mentioned in the templates.json document, to automatically add customer tags based on the product tags in an order.

You can also use the "Tag customers that have created an account" template, as mentioned in the templates.json document, to add a tag to customers who have created an account in your store.
