# Connection

Most modules provided by Stencil in Integromat requires authentication to properly work.

### Connection

Integromat uses Connection object to do this. When you use any module that requires authentication, you need to either add new connection or use existing connection.

The image below shows an example of `Create Image Asynchronously` module that will ask for Connection. Simply provide the project's API key to create new Connection.

{% hint style="info" %}
Due to the nature of API Key being scoped to a single project, connection object will inherit the behavior too. You need to use the right connection for the right project.
