Overview
This node integrates with the Mercado Pago API to manage payment-related operations. Specifically, for the Payment > Refund operation, it allows users to refund a previously made payment by providing the payment's unique ID.
Common scenarios where this node is beneficial include:
- Automating refunds in e-commerce workflows when customers request returns.
- Managing payment reversals in subscription or service platforms.
- Integrating refund processes into broader business automation pipelines.
For example, after detecting a refund request in a CRM system, this node can be used to trigger the refund process automatically by passing the payment ID to the Mercado Pago API.

Dependencies
- Requires an active Mercado Pago API credential configured in n8n for authentication.
- Internet access to call the Mercado Pago REST API at
https://api.mercadopago.com. - Proper permissions on the Mercado Pago account to perform refund operations.
Troubleshooting
- Missing Payment ID: If the "Payment ID" property is empty or invalid, the node will throw an error indicating that the payment ID is mandatory. Ensure you provide a valid payment ID string.
- API Authentication Errors: If the API key or credentials are incorrect or expired, the node will fail to authenticate. Verify your Mercado Pago API credentials in n8n.
- Refund Not Allowed: Some payments may not be refundable due to their status or time elapsed. The API response will indicate such issues; check the payment status before attempting a refund.
- Network Issues: Connectivity problems can cause request failures. Confirm network access and retry if necessary.
- Continue On Fail: If enabled, the node will continue processing subsequent items even if one refund fails, returning error messages in the output.
