defmodule ShopifexWeb.WebhookController do
@moduledoc """
You can use this module inside of another one of your application controllers.
The conn, shop and topic will be called by handle_topic/3 which you can define in your parent controller.
Example:
```elixir
use ShopifexWeb.WebhookController
def handle_topic(conn, shop, "app/uninstalled") do
Shopifex.Shops.delete_shop(shop)
conn
|> send_resp(200, "success")
end
# Mandatory Shopify shop data erasure GDPR webhook. Simply delete the shop record
def handle_topic(conn, shop, "shop/redact") do
Shopifex.Shops.delete_shop(shop)
conn
|> send_resp(204, "")
end
# Mandatory Shopify customer data erasure GDPR webhook. Simply delete the shop (customer) record
def handle_topic(conn, shop, "customers/redact") do
Shopifex.Shops.delete_shop(shop)
conn
|> send_resp(204, "")
end
# Mandatory Shopify customer data request GDPR webhook.
def handle_topic(conn, _shop, "customers/data_request") do
# Send an email of the shop data to the customer.
conn
|> send_resp(202, "Accepted")
end
