Tiny ERPInstall

Overview

This node integrates with the Tiny ERP system to manage product stock information. Specifically, the Product Stock - Update operation allows users to update the stock quantity of a specific product in a particular deposit (warehouse or storage location). This is useful for inventory management workflows where stock levels need to be adjusted based on sales, restocking, or transfers.

Common scenarios:

• Automatically updating stock quantities after an order is fulfilled.
• Syncing stock levels between Tiny ERP and other inventory systems.
• Adjusting stock counts during stocktaking or manual corrections.

Practical example:
You have an e-commerce store connected to n8n. After a customer places an order, you use this node to decrease the stock quantity of the purchased product in the relevant warehouse deposit within Tiny ERP, ensuring your inventory stays accurate.

Properties

Output

The node outputs a JSON object representing the response from the Tiny ERP API after updating the stock. This typically includes confirmation details about the updated stock entry.

Example output structure:

{
  "deposito": {
    "id": 123
  },
  "quantidade": 50,
  "tipo": "B",
  "otherResponseFields": "..."
}

• deposito.id: The ID of the deposit where stock was updated.
• quantidade: The updated quantity of the product stock.
• tipo: A fixed value "B" indicating the type of stock update (business logic internal to Tiny ERP).

No binary data output is produced by this operation.

Dependencies

• Requires an active connection to the Tiny ERP API.
• Requires an API authentication credential configured in n8n (an OAuth2 token or API key).
• The node uses the Tiny ERP REST API endpoints to perform stock updates.

Troubleshooting

• Error: "The operation 'updateStock' is not supported for resource 'produto_estoque'"
  This error indicates that the selected operation does not match the resource. Ensure you select the correct resource (produto_estoque) when performing stock updates.

• API Authentication Errors
  If the node fails due to authentication issues, verify that the API credentials are correctly set up and have sufficient permissions to update stock.

• Invalid Product or Deposit ID
  Providing incorrect or non-existent product or deposit IDs will cause the API to return errors. Double-check these IDs before running the workflow.

• Quantity Validation
  Ensure the quantity is a valid number. Negative values or invalid types may cause the API to reject the request.
