## Overview

The Caplin RET Adapter Toolkit contains classes that enable you to create a suite of integration adapters that integrate a Refinitiv [Electronic Trading](https://www.lseg.com/en/fx/workflows/electronic-trading) system with the Caplin Platform.

Each adapter class is designed to integrate a specific set of RET functionality or data into a Caplin Platform environment. The classes handle the translation of RET messages into Caplin message specifications and vice versa, as well as handling other business logic.

Here’s a list of the adapter classes:

* **Calendar Adapter** - Used to provide Tenor dates and Settlement dates when setting up trades.
* **FX Trading Adapter** - Used to facilitate FX trading with functions that include ESP and RFS using a RET-AD system.
* **LBN Adapter** - Used to provide historic blotter data detailing the user’s open (active) and executed deals.
* **Order Adapter** - Used to set up Order tickets, and to provide Orders functionality.
* **Pricing Adapter** - Used to deliver streaming prices (rates) via a RET-AD system.
* **Permissioning Adapter** - Provides a permissions framework for use with Caplin Platform data, as well as providing an integration point for an external permissions service.
* **Common Config Adapter** - Used to configure an Activity Blotter to receive data from the Order Adapter, as well as from the FX Trading Adapter.

For a full list of features, see [Adapter features](../../ret-adapter-suite/ret-adapters-feature-list.md) for more detail.
