How to connect multiple HubSpot accounts to Claude

Claude's built-in HubSpot connector works well if you use one HubSpot account. But when you connect a second account, it replaces the first.

If you manage separate HubSpot accounts for different products, regions, or business units, that quickly becomes frustrating.

Composio fixes this by keeping each HubSpot account separate and giving it a simple name, such as hubspot-1, hubspot-2, or hubspot-3. Claude can then use the right HubSpot account when you mention that name.

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

For example:

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

Using the hubspot-1 account, archive a batch of outdated contact records.

• A Claude account
• A free Composio account
• Access to each HubSpot 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 HubSpot account

In a new Claude chat, type:

Connect my hubspot-1 HubSpot account to Composio. Call it hubspot-1.

Claude will give you a sign-in link.

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

Claude should confirm that the account is connected.

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

• hubspot-1
• hubspot-2
• hubspot-3

Step 3: Connect your second HubSpot account

In the same Claude chat, type:

Connect another HubSpot account. Call it hubspot-2.

Claude will give you a new sign-in link.

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

Claude should confirm that hubspot-2 is connected.

Important: Check that HubSpot 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 HubSpot account you want to add. Give each connection a short, descriptive name such as hubspot-1, hubspot-2, hubspot-3, or client-acme.

Step 4: Check your connected HubSpot accounts

Ask Claude:

List my connected HubSpot 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 HubSpot account.

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

Step 5: Use the right HubSpot account

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

Review activity across accounts

Check hubspot-1 and hubspot-2 for anything new in HubSpot from the last 14 days. Group the results by account.

Associate a web form with current campaign

Using the hubspot-1 account, associate a web form with current campaign.

Add a custom data token to event template

Using the hubspot-2 account, add a custom data token to event template.

Find something across accounts

Search all connected HubSpot 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 HubSpot accounts are: hubspot-1 = my main account, hubspot-2 = my second account, and hubspot-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.

If Claude's built-in HubSpot connector is also enabled, Claude may use it instead of Composio. For a clearer setup, turn off the built-in connector or explicitly tell Claude to use HubSpot through Composio.

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 HubSpot.
5. Click Connect and complete the HubSpot authorisation flow.
6. Click Connect again to add another HubSpot account. Composio keeps it as a separate connection instead of replacing the first.
7. Give each connection a clear label, such as hubspot-1, hubspot-2, or hubspot-3.

If HubSpot 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 hubspot-2 is no longer useful.
• Disconnect or delete an account you no longer want Claude to access.
• Re-authorise an expired or revoked connection.
