How to connect multiple Zoho bigin accounts to Claude

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

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

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

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

For example:

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

Using the zoho_bigin-1 account, add new contact to sales pipeline.

• A Claude account
• A free Composio account
• Access to each Zoho bigin 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 Zoho bigin account

In a new Claude chat, type:

Connect my zoho_bigin-1 Zoho bigin account to Composio. Call it zoho_bigin-1.

Claude will give you a sign-in link.

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

Claude should confirm that the account is connected.

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

• zoho_bigin-1
• zoho_bigin-2
• zoho_bigin-3

Step 3: Connect your second Zoho bigin account

In the same Claude chat, type:

Connect another Zoho bigin account. Call it zoho_bigin-2.

Claude will give you a new sign-in link.

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

Claude should confirm that zoho_bigin-2 is connected.

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

Step 4: Check your connected Zoho bigin accounts

Ask Claude:

List my connected Zoho bigin 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 Zoho bigin account.

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

Step 5: Use the right Zoho bigin account

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

Review activity across accounts

Check zoho_bigin-1 and zoho_bigin-2 for anything new in Zoho bigin from the last 14 days. Group the results by account.

List all open deals this week

Using the zoho_bigin-1 account, list all open deals this week.

Tag recent leads as 'hot prospects'

Using the zoho_bigin-2 account, tag recent leads as 'hot prospects'.

Find something across accounts

Search all connected Zoho bigin 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 Zoho bigin accounts are: zoho_bigin-1 = my main account, zoho_bigin-2 = my second account, and zoho_bigin-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 Zoho bigin 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 Zoho bigin 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 Zoho bigin.
5. Click Connect and complete the Zoho bigin authorisation flow.
6. Click Connect again to add another Zoho bigin account. Composio keeps it as a separate connection instead of replacing the first.
7. Give each connection a clear label, such as zoho_bigin-1, zoho_bigin-2, or zoho_bigin-3.

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