# NATS Proxy

In NATS Proxy, set up a data connection with multiple Litmus Edge instances or  with a Litmus Edge instance and another developer application.  

## NATS Proxy Use Cases

 Consider the following use cases for using NATS Proxy. Setup a connection with:

- Two Litmus Edge instances. Data in one instance is sent through a NATS connector that receives and visualizes the data in the other instance. 
- Three or more Litmus Edge instances. Data in one instance is sent through a NATS connector that receives and visualizes the data in multiple instances. 
- One Litmus Edge instance and an external developer application. Data in the instance is sent through a NATS connector and the developer application is set up as a NATS client to subscribe to and receive NATS data.

Review the how-to guide to [Set Up Edge Cascading with the NATS Connector](docId\:IzyLU8iSR4fbq69hQfdkW). 

# API Credentials

:::hint{type="info"}
**Note**: This feature is only available on the Scale plan. 
:::

This section allows users to create, edit, remove and validate API credentials for API access. Optionally, create an API Key or OAuth 2.0 client credentials. 

To make requests and updates using a REST API endpoint, you need to use curl from the command line or a GUI-based software like Postman. See [Test REST API using Postman or Curl](docId\:oCk-ghZpTtJGSb1kIYAj_). 

# Access Accounts

This section allows users to create new accounts, enable or disable accounts and modify topics, view the API key, reset the account and remove the account.

# Access Tokens UI

From the Litmus Edge navigation menu, navigate to **System **> **Access Control **> **Tokens**.
