# Systems (Old)

The individual platforms that DCKAP Integrator directly connects to, or connects using APIs are known as systems. *For example*, ERP is a system. These systems need to be configured in DCKAP Integrator in order to be able to communicate with them (read, write, and update data).

## Add/Edit System

Click on the Add New button on the Systems page. Here users will be able to choose any existing public system and configure its credentials. These credentials will be used to authorize the API connections in flows. 

#### Step 1: Choose a system

## Private Systems

If you cannot find the system that you are looking for, you can create a private system and use it. These systems are private and only accessible to the project members.
