# Process Payment ## **Retrieve Supported Crypto Currencies and Prices** Call the Orangepill API to receive a list of Ramp accounts and supported crypto currencies. Use endpoint `https://api.orangepill.cloud/v1/accounts?query=:{"type":"ramp"}&fields=asset.` In response you will get the list of Ramp accounts assets. Display the current price for each currency by calling the Orangepill API to [retrieve price data](/smartapps/exchange-rates.md#get-price). ## **Create a Customer Profile** Create a customer profile, ensuring at least the customer's email is set. This email will be used to send successful payment notifications. Optionally, fill in the [complete customer profile](/orangepill-api/persons-and-companies.md#create-person-and-identity) information. Call the Orangepill API to check if the customer already exists. Use endpoint `https://api.orangepill.cloud/v1/identities/persons?email=EMAIL` to find customer with specific email. If the customer doesn't exist, use the Orangepill API to onboard the new customer. Check documentation on [creating new customer](#create-a-customer-profile). ## **Create a Payment Request** Call the Orangepill API to create a new [Apps.Payment](/smartapps/accept-blockchain-payments.md) object for the payment request. As a destination use alias of merchants virtual account. Display the payment amount in the selected currency and a unique blockchain address where the payment should be made. Show a timer indicating the timespan within which the payment needs to be completed. ## **Implement Websocket Client for Payment Notifications** Implement a websocket client to listen for notifications on the payment status. When a payment status update is received, process the notification accordingly. Check documentation on [WebSocket subscription](/websocket-subscriptions.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
