# Third-party Integrations (On Premise)

> Configure third-party integrations on a self-hosted Formbricks instance.

Formbricks connects to third-party tools such as Slack, Notion, or Google Sheets on behalf of your users. On
Formbricks Cloud we register and operate the OAuth apps behind those connections, so they work out of the
box. A self-hosted instance talks to those services under your own identity instead, which means you
register the OAuth app yourself and hand its credentials to your instance.

<Note>
  Using Formbricks Cloud? You do not need any of this. Head to the [Cloud integration
  guides](/docs/platform/features/integrations/overview) instead.
</Note>

## Before you configure an integration

<Steps>
  <Step title="Know your public-facing URL">
    Every OAuth app needs a redirect URL that points back at your instance, built from your own
    `https://<your-public-facing-url>` rather than `app.formbricks.com`. The callback path differs per
    service, so take it from the guide you are following.
  </Step>

  <Step title="Serve Formbricks over HTTPS">
    Slack refuses to talk to an instance without a valid certificate, and the other providers expect HTTPS in
    production too. See [Custom SSL](/docs/self-hosting/configuration/custom-ssl) if you have not set this up yet.
  </Step>

  <Step title="Restart after changing environment variables">
    Credentials go into the same place as every other setting — see [Environment
    Variables](/docs/self-hosting/configuration/environment-variables). Restart your containers for new values to
    take effect.
  </Step>
</Steps>

## What each integration needs

The integrations fall into two groups. The first four need credentials from an OAuth app you register with
the third-party service. The last three connect from the other side — through a Formbricks API key or your
instance URL — and need no server configuration at all.

| Integration                                                             | What you register                                        | Environment variables                                                                  |

Once an integration is enabled on your instance, connecting it to a survey works exactly as it does on
Formbricks Cloud. Follow the matching [Cloud guide](/docs/platform/features/integrations/overview) from there.

<Note>
  For automations that stay inside Formbricks — without a third-party tool — use
  [Workflows](/docs/workflows/overview) to trigger actions such as sending an email when a response is completed.
