# Integrations on Pandium

We handle all the devops while you focus on the App.

On Pandium, integrations are constructed as a simple Posix compliant [command line interface](https://en.wikipedia.org/wiki/Command-line_interface) application (CLI). The CLI should read tenant configuration and connector secrets from [environment variables](https://docs.pandium.com/getting-started/anatomy-of-an-integration/environment-variables). Any logs you wish to display to your end users should be written to [`stderr`](https://docs.pandium.com/getting-started/anatomy-of-an-integration/environment-variables/stderr).

One can pass information to the next run by writing a json encoded string to [`stdout`](https://docs.pandium.com/getting-started/anatomy-of-an-integration/environment-variables/stdout). On the next run it will be injected in as an environment variable named `PAN_CTX_LAST_RUN_STDOUT` or `PAN_CTX_LAST_SUCESSFUL_RUN_STDOUT.`
