How do I find my Holded API Key?

Log in to your Holded account, click on the **Settings** icon (top right), go to **Developers**, and you will find your unique **API Key** listed there. You can create multiple keys for different integrations.

What document types are supported in the invoicing tools?

This integration currently focuses on the `invoice` document type. For other types like sales orders or purchase orders, you can use the generic `list_invoices` logic if they are mapped under the same module in your instance.

Can I update stock levels through this integration?

Yes! Use the `update_product_stock` tool. You must provide the product ID and a JSON string containing the warehouse ID and the new quantity to update your inventory.

Is the integration secure for ERP data?

Absolutely. The integration uses official Holded API keys in the request header over HTTPS. Your credentials and business data are encrypted and stored securely within the Vinkius Cloud infrastructure.

How does AutoGen connect to MCP servers?

Create an MCP tool adapter and assign it to one or more agents in the group chat. AutoGen agents can then call Holded tools during their conversation turns.
