# How to register your own Slack OAuth app

> Register an OAuth app with Slack and connect it to Nango

This guide shows you how to register your own app with Slack to obtain your OAuth credentials (client id & secret). These are required to let your users grant your app access to their Slack workspace.

<Steps>
  <Step title="Create a developer account">
    Go to [Slack Developer Program signup page](https://api.slack.com/developer-program) and click Join the Program.
  </Step>

  <Step title="Create & configure a Slack app">
    1. Click on the **Your Apps** button then **Create New App**.
    2. Choose how you'd like to configure your app's scopes and settings. You can use a manifest file or start from scratch; for a simpler flow, select **From scratch**.
    3. Add your **App name** and select a workspace to develop your app in, then click **Create App**.
    4. In the **Basic Information** tab, copy your app's `Client ID` and `Client Secret`, as you'll need them when configuring your integration in Nango.
  </Step>

  <Step title="Set up the OAuth scopes">
    1. In the left sidebar, select the **OAuth & Permissions** tab and configure the following Redirect URL: `https://api.nango.dev/oauth/callback`.
    2. Still in the **OAuth & Permissions** tab, under **Scopes**, add the scopes that are relevant to how you want to consume Slack's API.
       There are 2 types of scopes, [Bot Token Scopes](https://docs.slack.dev/reference/scopes/?token_types=Bot) and [User Token Scopes](https://docs.slack.dev/reference/scopes/?token_types=User).

    * Bot tokens represent a bot associated with an app installed in a workspace. They govern what your app can access. They will be added to Nango when creating a Slack integration.
    * User token Scopes access user data and act on behalf of users that authorize them. They will be [added](/reference/api/connect/sessions/create#body-integrations-config-defaults-key-user_scopes) to Nango when creating a Slack connection.
  </Step>

  <Step title="Create a Slack Developer Sandbox (Optional)">
    If you don't have a Slack Developer Sandbox already, head over to Slack's [Developer Program dashboard](https://api.slack.com/developer-program/dashboard) and provision one to test your integration.
  </Step>

  <Step title="Next">
    Follow the [*Quickstart*](/getting-started/quickstart).
  </Step>
</Steps>
