# Work across installations

> Understand how Connector Studio scopes projects and organizations to a Grand Central installation.

Connector Studio shows the connectors, organizations, API specifications, and mappings that belong to the installation you select in Grand Central. Confirm which installation you're in before you start work.

## How installations scope your work

Two things change when you switch installations:

* **What you see:** Each installation has its own **Connector Projects** list, organizations, mappings, routes, and uploads. The same account can see a different set of projects in each one. You can't use a project or an organization from one installation in another.
* **What you can do:** You have a separate role in each installation.

<Warning>
  Administrator access doesn't carry over between installations. You can be an administrator in one installation and a viewer in another. To use administrator features in an installation, you need the administrator role in that installation, not in the one you came from.
</Warning>

## Switch installations

<Steps>
  <Step title="Open the switcher">
    Select the installation switcher in the Grand Central header.
  </Step>

  <Step title="Select the installation">
    Select the installation where you want to create or review connectors.
  </Step>

  <Step title="Confirm the context">
    Open Connector Studio and go to **Connector Projects**. Check that the header shows the installation you expect, and that the project list matches it.
  </Step>
</Steps>

Project counts change over time, so use the installation name and the project list together to confirm where you are.

## Prepare an installation

The first time anyone uses Connector Studio in an installation, that installation needs its requester and responder organizations. Which path you take depends on whether those organizations are already there.

To find out, open **Connector Projects** > **New Project** and check the **Requester** and **Responder** lists:

* If both organizations are available, create the first connector yourself. See [Option B](#option-b-create-the-first-connector).
* If either organization is missing, ask a Grand Central administrator to prepare the installation. See [Option A](#option-a-ask-an-administrator-to-prepare-the-installation).

The following table compares the two paths:

| Option                 | Who does it                   | When to use it                                                                                   |
| :--------------------- | :---------------------------- | :----------------------------------------------------------------------------------------------- |
| A. Administrator setup | A Grand Central administrator | An organization is missing, or you want the installation ready before anyone creates a connector |
| B. First connector     | A connector creator           | The requester and responder organizations are already available                                  |

### Option A: Ask an administrator to prepare the installation

A Grand Central administrator completes the following steps.

<Steps>
  <Step title="Select the installation">
    In Grand Central, select the installation with the installation switcher.
  </Step>

  <Step title="Open Workspaces">
    In Connector Studio administration, open **Workspaces** and select the workspace that matches the installation.
  </Step>

  <Step title="Assign the organizations">
    Assign the vendors and any other organizations that take part, then save the assignments.
  </Step>

  <Step title="Hand over">
    Ask the connector creator to refresh Connector Studio and continue with Option B.
  </Step>
</Steps>

<Note>
  Grand Central administrators manage workspaces centrally, so the **Workspaces** page can list workspaces from more than one installation. **Connector Projects** always follows the installation you select in Grand Central.
</Note>

### Option B: Create the first connector

Use the standard connector creation flow. Connector Studio prepares the installation automatically when you submit the first connector.

<Steps>
  <Step title="Confirm the installation">
    Check the installation name in the Grand Central header.
  </Step>

  <Step title="Start a project">
    From **Connector Projects**, select **New Project**.
  </Step>

  <Step title="Complete the form">
    Choose the requester, the responder, and the connector category. Add the authentication and description values if you need them.
  </Step>

  <Step title="Create the connector">
    Select **Create Connector**, then review the project that Connector Studio creates.
  </Step>
</Steps>

If you can't select a requester or a responder, ask a Grand Central administrator to add the missing organization in **Workspaces**. Then refresh Connector Studio and try again.

## Check before you start

Run through this list at the start of a session:

* The installation name in the Grand Central header is the one you expect.
* The **Connector Projects** list matches that installation.
* The requester and responder organizations you need are available.

If anything looks wrong, switch installation, or ask a Grand Central administrator to check **Workspaces**.
