# FAQ

<details>

<summary>What authentication method does Cin7 use with Coupler.io?</summary>

Cin7 uses API key authentication. You'll need your **API Username** and **API Key** from Cin7, which you can find under **Settings > Integrations > API** in your Cin7 account. There's no OAuth flow — just copy and paste the credentials into Coupler.io.

</details>

<details>

<summary>Can I connect multiple Cin7 accounts in the same data flow?</summary>

Yes. Add each Cin7 account as a separate source block within the same data flow, then use the **Append** transformation to combine the records. This is useful if you run separate Cin7 accounts by region, brand, or warehouse.

<details>

<summary>What's the difference between Sale lists and Sales?</summary>

**Sales** contains one row per transaction with summary-level data like total revenue, COGS, and margin. **Sale lists** contains one row per line item within each order, so you can see exactly which products were sold. Use Sales for revenue reporting and Sale lists for product-level analysis.

</details>

<details>

<summary>What's the difference between Purchase lists and Purchases?</summary>

Same pattern as sales — **Purchases** is the transaction-level summary (total cost, supplier, payment status), while **Purchase lists** is the line-item detail (which products, quantities, and unit costs were on each PO). Use both if you need a complete picture of procurement.

</details>

<details>

<summary>Can I get historical stock level data from Cin7?</summary>

Cin7's API returns current stock levels, not a historical log. To build a stock history, configure your Coupler.io data flow to **append** data on each run rather than overwrite it. Each sync will add a new snapshot with a timestamp, giving you a time series over time.

</details>

<details>

<summary>Why are my CRM entities (Leads, Deals, Opportunities) empty?</summary>

These entities only contain data if you actively use Cin7's built-in CRM module. If your team uses a separate CRM tool, these entities won't have records. Check in Cin7 whether the CRM module is enabled and whether records exist.

</details>

<details>

<summary>Can I send Cin7 data to an AI tool like ChatGPT or Claude?</summary>

Yes. Coupler.io supports AI destinations including ChatGPT, Claude, Gemini, Cursor, Perplexity, and OpenClaw. You can route any Cin7 entity — for example, Sales or Opportunities — directly to an AI destination for analysis, forecasting, or automated reporting.

</details>

<details>

<summary>How do I analyze revenue by product using Cin7 data?</summary>

Add both the **Sales** and **Products** entities as source blocks in the same data flow, then use Coupler.io's **Join** transformation to link them on the shared product or SKU identifier. This gives you a combined dataset with transaction revenue alongside product details like cost price, category, and brand.

</details>

<details>

<summary>Is Cin7 API access available on all plans?</summary>

No — API access is typically available on Cin7's Business and Enterprise plans. If you can't find the API section under **Settings > Integrations**, contact Cin7 support to confirm whether your plan includes it.
