N8N Tools - Cash AppInstall

Overview

The node integrates with the Cash App API to manage various business-related resources such as payments, customers, products, inventory, subscriptions, invoices, loyalty accounts, gift cards, and reports. Specifically, for the Product - Get Product operation, it retrieves detailed information about a specific product from the Cash App catalog using its unique product ID.

This node is beneficial in scenarios where you need to automate product data retrieval within workflows, such as syncing product details with other systems, updating inventories, or generating reports based on product information.

Example use case:
You have an e-commerce platform integrated with Cash App for payment and product management. Using this node, you can automatically fetch product details by product ID to update your internal database or trigger further actions like pricing updates or stock checks.

Properties

Output

The node outputs a JSON object containing the retrieved product details under the key product. The structure corresponds to the product data returned by the Cash App API catalog endpoint. It typically includes fields such as product name, description, price, SKU, and other metadata related to the product.

Example output snippet:

{
  "product": {
    "id": "product_123456789",
    "name": "Sample Product",
    "description": "Detailed description here",
    "price": 2500,
    "currency": "USD",
    ...
  },
  "resource": "product",
  "operation": "getProduct",
  "success": true,
  "creditsUsed": 1,
  "creditsRemaining": 99
}

No binary data output is involved in this operation.

Dependencies

• Requires an active connection to the external Cash App API via an API key credential.
• The node uses a custom API wrapper (CashAppApi) internally to communicate with the Cash App endpoints.
• Proper configuration of the API URL and API key is necessary in the node credentials.
• The node sends a validation request to the API before performing the main operation to ensure the resource and operation are supported and authorized.

Troubleshooting

• Common issues:

  • Invalid or missing Product ID will cause the operation to fail.
  • Incorrect or expired API key credential may result in authentication errors.
  • Network connectivity problems can prevent successful API calls.
  • If the product ID does not exist in the Cash App catalog, the API will return an error.

• Error messages:

  • "N8N Tools API validation failed": Indicates that the API rejected the requested resource-operation combination or the API key is invalid.
  • "Unknown product operation: getProduct": Should not occur if configured correctly; indicates a possible mismatch in operation naming.
  • "Cash App operation failed: <message>": General failure message with details from the API response.

• Resolution tips:

  • Verify the Product ID is correct and exists in your Cash App catalog.
  • Check that the API key credential is valid and has sufficient permissions.
  • Ensure network access to the Cash App API endpoint.
  • Enable "Continue On Fail" in the node settings to handle errors gracefully in workflows.
