# Configuration

## How to set environment variables?

You can modify the `docker-compose.yml` file to override environment variables. Please do not forget to change in `main` and `worker` services of docker-compose since the following variables might be used in both.

## Environment Variables

:::warning
The default values for some environment variables might be different in our development setup but following table shows the default values for docker-compose setup, which is the recommended way to run the application.
:::

:::danger
Please be careful with the `ENCRYPTION_KEY` and `WEBHOOK_SECRET_KEY` environment variables. They are used to encrypt your credentials from third-party services and verify webhook requests. If you change them, your existing connections and flows will not continue to work.
