# FAQ

<details>

<summary>Where do I find my Zoho Books API key?</summary>

Your Zoho Books API key (auth token) is generated from your Zoho account, not from within Zoho Books itself. Go to **accounts.zoho.com**, navigate to **Security > App Passwords** or use the Zoho API console at **api-console.zoho.com** to generate an auth token. The exact path can vary by Zoho region and account type.

You'll also need your **Organization ID**, which is found under **Settings > Organization Profile** inside Zoho Books.

</details>

<details>

<summary>Can I connect multiple Zoho Books organizations?</summary>

Yes. Create a separate source connection in Coupler.io for each organization, using the corresponding Organization ID. You can then use the **Append** transformation to combine data from all organizations into a single destination sheet or table.

</details>

<details>

<summary>Which entity should I use for a full transaction history?</summary>

Use the **Transactions** entity for a complete ledger-level view of all financial activity. If you need documents like invoices or bills specifically, use those dedicated entities — they include document-level fields like due dates and statuses that the Transactions entity doesn't have.

</details>

<details>

<summary>Can I pull data from Zoho Books into a spreadsheet for month-end reporting?</summary>

Absolutely. Connect Zoho Books to Google Sheets or Excel as your destination. Pull Invoices, Bills, and Expenses, then use the Aggregate transformation to summarize totals by month or category. Schedule the data flow to refresh at the start of each month for a ready-to-use report.

</details>

<details>

<summary>Does Coupler.io support Zoho Books across all regional data centers (US, EU, IN, AU)?</summary>

Zoho Books operates on regional data centers (e.g., zoho.com, zoho.eu, zoho.in). Make sure the API key and Organization ID you use match the region where your Zoho Books account is hosted. If you're having connection issues, confirm that you're using credentials from the correct regional Zoho account.

</details>

<details>

<summary>How do I track unpaid invoices automatically?</summary>

Pull the **Invoices** entity and filter by the `status` field for `Overdue` or `Sent` (unpaid) values in your destination. In Google Sheets or Looker Studio, you can build a live AR aging view using the `due_date` and `balance` fields. Schedule the data flow to refresh daily so the list stays current.

</details>

<details>

<summary>Can I use Zoho Books data with AI tools?</summary>

Yes. Coupler.io supports AI destinations including ChatGPT, Claude, Gemini, Cursor, Perplexity, and OpenClaw. You can route your Expenses or Invoices data directly to these tools to generate financial summaries, flag unusual transactions, or answer questions about your business finances in natural language.
