# Zapier
This documentation explains the steps to create a Zap that will trigger an email to be sent to your customers as soon as their payment is completed using Copperx as the payment gateway.
To create Zapier Automation:
1. Login to your [Zapier](https://zapier.com/) account and click on the **Create Zap** button from the Sidebar.
2. Now in the **Trigger**, search for the "Copperx" app and select **Checkout Session Completed** as the event and click **Continue**.
3. Next is to test the trigger, for that you need to copy the **webhook URL** and add it to the Copperx [webhooks settings](https://dashboard.copperx.io/developer/webhooks) as new webhook endpoint. (**Note :** you can test trigger by switching to Testnet and adding the copied URL to webhooks settings, but be sure to remove the URL from Testnet after the successful payment test.)
4. Next, select the email app you want to use as the **Action** app. For example, you could choose Gmail, Outlook, or any other email service and select "Send Email" as the event. Now, click **Continue** and log in to your email service.
5. Now, you need to fill the **Email** **To** field as the "Customer Email" from the given option data and fill other relevant fields such as email subject and body as per your business needs.
6. At this stage, you can test your Zap and **Publish** it.
Once you've completed these steps, you're ready to send customized emails to your customers through this automation.
