# Set up a Blackline connector

> C1 provides identity governance for Blackline. Integrate your Blackline instance with C1 for unified visibility and governance over user access.

<Warning>
  **This connector is in beta.** This means it's undergoing ongoing testing and development while we gather feedback, validate functionality, and improve stability. Beta connectors are generally stable, but they may have limited feature support, incomplete error handling, or occasional issues.

  We recommend closely monitoring workflows that use this connector and contacting our Support team with any issues or feedback.
</Warning>

## Capabilities

| Resource | Sync                                                          | Provision |
| :------- | :------------------------------------------------------------ | :-------- |
| Account  | <Icon icon="square-check" iconType="solid" color="#c937ae" /> |           |
| Role     | <Icon icon="square-check" iconType="solid" color="#c937ae" /> |           |
| Team     | <Icon icon="square-check" iconType="solid" color="#c937ae" /> |           |

**Additional functionality:**

*None.*

## Gather Blackline configuration information

Configuring the connector requires you to pass in information from Blackline. Gather these configuration details before you move on.

Here's the information you'll need:

* Client ID
* Client Secret
* Username
* Password (API key)
* Scope
* Environment Subdomain

User must have an administrator role

Scopes are unique for each instance and must be requested from the Blackline support team.
The connector uses the following endpoints:

* User management API
  * GET /v1/users
  * GET	/v1/users/{id}/teams
* Team management API
  * GET	/v1/teams
  * GET /v1/teams/{teamId}/users
* Role Management API
  * GET /v1/roles

## Configure the Blackline connector

<Warning>
  **To complete this task, you'll need:**

  * The **Connector Administrator** or **Super Administrator** role in C1
  * Access to the set of Blackline configuration information gathered by following the instructions above

  <Tab title="Cloud-hosted">
    **Follow these instructions to use a built-in, no-code connector hosted by C1.**

    <Steps>
      <Step>
        In C1, navigate to **Integrations** > **Connectors** and click **Add connector**.
      </Step>

      <Step>
        Search for **Blackline** and click **Add**.
      </Step>

      <Step>
        Choose how to set up the new Blackline connector:

        * Add the connector to a currently unmanaged app (select from the list of apps that were discovered in your identity, SSO, or federation provider that aren't yet managed with C1)
        * Add the connector to a managed app (select from the list of existing managed apps)
        * Create a new managed app
      </Step>

      <Step>
        Set the owner for this connector. You can manage the connector yourself, or choose someone else from the list of C1 users. Setting multiple owners is allowed.
        If you choose someone else, C1 will notify the new connector owner by email that their help is needed to complete the setup process.
      </Step>

      <Step>
        Click **Next**.
      </Step>

      <Step>
        Find the **Settings** area of the page and click **Edit**.
      </Step>

      <Step>
        Enter the configuration information from the previous section.
      </Step>

      <Step>
        Click **Save**.
      </Step>

      <Step>
        The connector's label changes to **Syncing**, followed by **Connected**. You can view the logs to ensure that information is syncing.
      </Step>
    </Steps>

    **Done.** Your Blackline connector is now pulling access data into C1.
  </Tab>

  <Tab title="Self-hosted">
    **Follow these instructions to use the Blackline connector, hosted and run in your own environment.**

    When running in service mode on Kubernetes, a self-hosted connector maintains an ongoing connection with C1, automatically syncing and uploading data at regular intervals. This data is immediately available in the C1 UI for access reviews and access requests.

    [Contact C1's support team](mailto:support@c1.ai) to download the latest version of the connector.

    ### Step 1: Set up a new Blackline connector

    <Steps>
      <Step>
        In C1, navigate to **Integrations** > **Connectors** > **Add connector**.
      </Step>

      <Step>
        Search for **Baton** and click **Add**.
      </Step>

      <Step>
        Choose how to set up the new Blackline connector:

        * Add the connector to a currently unmanaged app (select from the list of apps that were discovered in your identity, SSO, or federation provider that aren't yet managed with C1)
        * Add the connector to a managed app (select from the list of existing managed apps)
        * Create a new managed app
      </Step>

      <Step>
        Set the owner for this connector. You can manage the connector yourself, or choose someone else from the list of C1 users. Setting multiple owners is allowed.
        If you choose someone else, C1 will notify the new connector owner by email that their help is needed to complete the setup process.
      </Step>

      <Step>
        Click **Next**.
      </Step>

      <Step>
        In the **Settings** area of the page, click **Edit**.
      </Step>

      <Step>
        Click **Rotate** to generate a new Client ID and Secret.
        Carefully copy and save these credentials. We'll use them in Step 2.
      </Step>
    </Steps>

    ### Step 2: Create Kubernetes configuration files

    Create two Kubernetes manifest files for your Blackline connector deployment:

    #### Secrets configuration

    ```yaml expandable theme={"theme":{"light":"css-variables","dark":"css-variables"}}
    # baton-blackline-secrets.yaml
    apiVersion: v1
    kind: Secret
    metadata:
      name: baton-blackline-secrets
    type: Opaque
    stringData:
      # C1 credentials
      BATON_CLIENT_ID: <C1 client ID>
      BATON_CLIENT_SECRET: <C1 client secret>

      # Blackline config
      BATON_BLACKLINE_CLIENT_ID: <Client ID for your Blackline instance>
      BATON_BLACKLINE_CLIENT_SECRET: <Client Secret for your Blackline instance>
      BATON_BLACKLINE_ENVIRONMENT: <Environment where your Blackline instance is running (e.g. 'us' or 'eu')  See: https://developer.blackline.com/get-started>
    ```

    See the connector's README or run `--help` to see all available configuration flags and environment variables.

    #### Deployment configuration

    ```yaml expandable theme={"theme":{"light":"css-variables","dark":"css-variables"}}
    # baton-blackline.yaml
    apiVersion: apps/v1
    kind: Deployment
    metadata:
      name: baton-blackline
      labels:
        app: baton-blackline
    spec:
      selector:
        matchLabels:
          app: baton-blackline
      template:
        metadata:
          labels:
            app: baton-blackline
            baton: true
            baton-app: blackline
        spec:
          containers:
          - name: baton-blackline
            image: ghcr.io/conductorone/baton-blackline:latest
            imagePullPolicy: IfNotPresent
            env:
            - name: BATON_HOST_ID
              value: baton-blackline
            envFrom:
            - secretRef:
                name: baton-blackline-secrets
    ```

    ### Step 3: Deploy the connector

    <Steps>
      <Step>
        Create a namespace in which to run C1 connectors (if desired), then apply the secret config and deployment config files.
      </Step>

      <Step>
        Check that the connector data uploaded correctly. In C1, click **Apps**. On the **Managed apps** tab, locate and click the name of the application you added the Blackline connector to. Blackline data should be found on the **Entitlements** and **Accounts** tabs.
      </Step>
    </Steps>

    **Done.** Your Blackline connector is now pulling access data into C1.
