# Orders: Sample Use Case & Flow
This article shares a possible use case you could support, as well as a sample flow that could support the use case. 
This can be a helpful jumping off point as you plan your implementation.

## Send an email on successful payment of online orders

You can create an implementation that sends a [Wix Inbox](https://support.wix.com/en/article/wix-inbox-an-overview) confirmation email to customers that a payment was successful. 

To listen for successful payments and send a confirmation email to the customer, follow this flow:  
1. Listen to the [Payment Event](https://dev.wix.com/docs/rest/business-management/payments/cashier/cashier-pay/payment-event/payment.md).
1. When the event is triggered, check for a `wixAppId` of `1522827f-c56c-a5c9-2ac9-00f9e6ae12d3` (the Wix App ID for Pricing Plans) and extract the `wixAppOrderId`.
1. Call [Get Order](https://dev.wix.com/docs/rest/business-solutions/pricing-plans/pricing-plans/orders/member-orders-service-get-order.md) using the `wixAppOrderId` as the `id` for the order to retrieve.
1. Extract the `order.buyer.memberId` to retrieve the buyer's `memberId`.
1. Call [Get Member](https://dev.wix.com/docs/api-reference/crm/members-contacts/members/member-management/members/get-member.md) with the `memberId` and extract the member's `loginEmail`.
1. Call [Query Email Subscriptions](https://dev.wix.com/docs/api-reference/crm/communication/email-subscriptions/query-email-subscriptions.md) and filter by the email address to confirm that the member has agreed to receive emails from the Wix user.
1. Use [Get or Create Conversation](https://dev.wix.com/docs/api-reference/crm/communication/inbox/conversations/get-or-create-conversation.md) and [Send Message](https://dev.wix.com/docs/api-reference/crm/communication/inbox/messages/send-message.md) to send an email to the buyer.
