How to connect multiple Google Slides accounts to Claude

Claude does not have a built-in Google Slides connector. If you manage separate Google Slides accounts for different products, regions, or business units, you still need a way to connect them and choose the right account for each task.

Composio adds Google Slides to Claude and keeps each account separate. You can give every connection a simple name, such as googleslides-1, googleslides-2, or googleslides-3, and tell Claude which account to use.

• One Composio connector in Claude
• Two or more Google Slides accounts connected behind it
• A clear name for each account
• The ability to work in the right Google Slides account from a single Claude chat

For example:

Search my googleslides-1 and googleslides-2 Google Slides accounts for anything that needs my attention from the last 7 days. Tell me which account each item came from.

Using the googleslides-1 account, turn this meeting summary into slides.

• A Claude account
• A free Composio account
• Access to each Google Slides account you want to connect

If you use Claude Free, you can have one custom connector. If you already use that slot, you will need to remove the existing custom connector first.

If you use Claude Team or Enterprise, an Owner may need to add the connector for the organisation. Each member can then connect their own accounts.

Step 1: Add Composio to Claude (one-time process)

1. Click the button below. This will take you to the Claude Custom Connector modal.

Add to Claude

2. Click Continue

3. In the next modal, click Add

4. It will take you to the authentication page. Sign in to Composio and approve the connection.

Then return to Claude and make sure Composio is enabled.

Step 2: Connect your first Google Slides account

In a new Claude chat, type:

Connect my googleslides-1 Google Slides account to Composio. Call it googleslides-1.

Claude will give you a sign-in link.

1. Click the link.
2. Sign in to your googleslides-1 Google Slides account.
3. Review and approve Google Slides's permission request.
4. Return to Claude.

Claude should confirm that the account is connected.

The name googleslides-1 is how Claude knows which Google Slides account to use. Choose short, obvious names. Good examples include:

• googleslides-1
• googleslides-2
• googleslides-3

Step 3: Connect your second Google Slides account

In the same Claude chat, type:

Connect another Google Slides account. Call it googleslides-2.

Claude will give you a new sign-in link.

1. Open the link.
2. Sign in to the second Google Slides account.
3. Review and approve Google Slides's permission request.
4. Return to Claude.

Claude should confirm that googleslides-2 is connected.

Important: Check that Google Slides is showing the second account before you approve access. If the wrong account appears, sign out or open the link in an incognito or private window.

Repeat this step for every other Google Slides account you want to add. Give each connection a short, descriptive name such as googleslides-1, googleslides-2, googleslides-3, or client-acme.

Step 4: Check your connected Google Slides accounts

Ask Claude:

List my connected Google Slides accounts in Composio. Show each account's name and connection status.

You should see every account you added, and each connection should show as ACTIVE.

For an extra check, ask:

Show the account email or ID and the account name for each connected Google Slides account.

This helps you confirm that every label points to the correct Google Slides account and that you did not connect the same account twice.

Step 5: Use the right Google Slides account

Mention the account name whenever you ask Claude to work with Google Slides. This is especially important when an action could change data.

Review activity across accounts

Check googleslides-1 and googleslides-2 for anything new in Google Slides from the last 14 days. Group the results by account.

Add a new slide with project milestones

Using the googleslides-1 account, add a new slide with project milestones.

Update presentation with these markdown notes

Using the googleslides-2 account, update presentation with these markdown notes.

Find something across accounts

Search all connected Google Slides accounts for customer@example.com. Show which account it appears in and summarise the latest activity.

For actions such as creating, changing, or deleting data, ask Claude to show you the planned action first and wait for your confirmation.

Add this to your Claude preferences or project instructions, replacing the examples with your own account names:

My Google Slides accounts are: googleslides-1 = my main account, googleslides-2 = my second account, and googleslides-3 = a client account. Always use the named account when I specify one. If I do not name an account, ask me which one to use. Before creating, changing, or deleting anything, show me the planned action and wait for confirmation.

The chat method is the quickest way to connect accounts. Use the dashboard when you want to add, rename, reconnect, or remove a connection.

1. Go to dashboard.composio.dev.

2. Sign in with the same Composio account you connected to Claude.
3. Open For You from the product switcher.
4. Find Google Slides.
5. Click Connect and complete the Google Slides authorisation flow.
6. Click Connect again to add another Google Slides account. Composio keeps it as a separate connection instead of replacing the first.
7. Give each connection a clear label, such as googleslides-1, googleslides-2, or googleslides-3.

If Google Slides opens the wrong account during authorisation, sign out first or use an incognito or private window.

From the dashboard, you can also:

• Rename a connection when a default label such as googleslides-2 is no longer useful.
• Disconnect or delete an account you no longer want Claude to access.
• Re-authorise an expired or revoked connection.
