Tiny ERPInstall

Overview

This node integrates with the Tiny ERP API to manage products and their variations. Specifically, the "Delete Variation" operation under the "Product" resource allows users to delete a specific variation of a product by providing the product ID and the variation ID.

Common scenarios for this node include:

• Removing outdated or discontinued product variations from your inventory system.
• Cleaning up product catalogs by deleting incorrect or duplicate variations.
• Automating inventory management workflows where product variations need to be dynamically updated or removed.

For example, if you have a product with multiple size or color variations and one variation is no longer available, you can use this node to delete that variation programmatically.

Properties

Output

The output JSON contains a confirmation of the deletion operation with the following structure:

{
  "success": true,
  "productId": <number>,
  "variationId": <number>
}

• success: A boolean indicating whether the deletion was successful.
• productId: The ID of the product from which the variation was deleted.
• variationId: The ID of the deleted variation.

No binary data is output by this operation.

Dependencies

• Requires an active connection to the Tiny ERP API.
• Requires an API authentication token configured in n8n credentials (an OAuth2 API key credential).
• The node depends on the internal helper function to make HTTP requests to the Tiny ERP API endpoints.

Troubleshooting

• Error: "The operation 'deleteVariation' is not supported!"
  This error occurs if the operation name is misspelled or not implemented. Ensure the operation is exactly "deleteVariation" and the resource is "product".

• Error related to missing Product ID or Variation ID
  Both IDs are required. Make sure these fields are provided and valid numbers.

• API Authentication Errors
  If the API key or OAuth2 token is invalid or expired, the request will fail. Verify your credentials in n8n settings.

• Network or API Endpoint Issues
  If the Tiny ERP API is unreachable or returns errors, check network connectivity and API status.
