# Setting up an AS2 Server

An AS2 protocol is a file transfer protocol commonly used to securely transfer EDI files from one partner to another.

In this document, we will learn how to setup an AS2 Server in Astera.

### Configuring the AS2 Setup

1. To setup an AS2 Server go to the *Server Explorer*, right-click on *DEFAULT* and select the *AS2 Setup* option.

Let’s look at the different configuration options provided here.

* *Server URL* – This is the URL of your server where the AS2 service is active, listening for calls from your partner to transmit an EDI file.
* *AS2 ID* – A unique identifier which would allow our partner to identify our request to send a file.
* *Server Upload Directory* – Directory where we want to store all files sent through the AS2 request.
* *Public Certificate Path* – File path where our public certificate is stored.
* *Private Certificate Path and Password* – File path where the private certificate is stored along with its password.

**Note:** We can manage our certificates on the[ *Certificate Store*](https://documentation.astera.com/api-flow/api-publishing/develop/certificate-store)*.*
{% endhint %}

Now, let’s configure our AS2 Server:

3. Our AS2 server setup has now been configured. We can now save it and make use of our AS2 service to send and receive EDI files in Astera.
