# Overview

The Ledger Off-Ramp Wrapper leverages existing Transak APIs, facilitating seamless custom integration of the Off-Ramp functionality within the Ledger Live App. These Wrapper APIs are designed and implemented according to Ledger’s integration guidelines and [API documentation](https://developers.ledger.com/docs/exchange/sell).

## Key Features

* Seamless Integration: Easily integrates into the Ledger Live App, leveraging existing Transak APIs.
* Multi-Currency Support: Allows off-ramping of multiple popular cryptocurrencies into various fiat currencies.
* Transaction Updates: Receive real-time transaction status through webhooks

* [Create Sell Order](/api/ledger-off-ramp/create-sell-order)

## Interoperability Layer

* All APIs return results using Ledger's corresponding IDs instead of Transak's unique IDs. An interoperability layer is implemented to translate conventions supported by Transak into those supported by Ledger.
* For blockchain networks, mappings of naming conventions are maintained to consistently represent the same blockchain in both Transak and Ledger systems. This mapping is utilized across various APIs, such as [Capabilities](/api/ledger-off-ramp/get-capabilities) and [Quote](/api/ledger-off-ramp/get-quote).
* For cryptocurrencies, the naming conventions follow Ledger's standard, retrieved from [Ledger’s currency API](https://crypto-assets-service.api.ledger.com/v1/currencies?output=id,ticker,symbol,network) based on cryptocurrency symbols and associated networks.

## Authorization

All requests require authentication via an API key in the header.
`x-api-key` : Transak API key. This can be retrieved from Transak Dashboard
