N8N Tools - Cash AppInstall

Overview

The node integrates with the Cash App API via an extensible Square API interface to manage various business operations such as payments, customers, products, inventory, subscriptions, invoices, loyalty programs, gift cards, and reports. Specifically for the Customer - Update Customer operation, it updates the profile information of an existing customer in the Cash App system.

This node is beneficial in scenarios where you need to automate customer data management within your workflows, such as updating customer contact details, preferences, or other profile attributes after receiving new information from forms, CRM systems, or other sources.

Example use case:
Automatically update a customer's profile when they submit updated contact information through a web form integrated with n8n, ensuring your Cash App customer records stay current without manual intervention.

Properties

Note: Although not explicitly listed in the provided properties JSON, the node also expects a customerData object parameter containing the fields and values to update on the customer profile. This is inferred from the code usage but not detailed in the user-provided properties.

Output

The node outputs a JSON object representing the result of the update operation. The key field in the output JSON is:

• customer: Contains the updated customer profile object returned by the Cash App API after the update operation.

The output structure looks like this (simplified example):

{
  "json": {
    "resource": "customer",
    "operation": "updateCustomer",
    "success": true,
    "creditsUsed": 1,
    "creditsRemaining": 99,
    "customer": {
      "id": "customer_123456789",
      "name": "Updated Customer Name",
      "email": "updated.email@example.com",
      "...": "other updated fields"
    }
  }
}

No binary data output is involved in this operation.

Dependencies

• Requires an API key credential and API URL configuration for the external "N8N Tools API" service that validates and proxies requests to the Cash App API.
• Uses OAuth2 credentials for authenticating with Cash App services.
• The node depends on the bundled cashapp-api helper class to perform the actual API calls.
• Proper configuration of these credentials and API endpoints in n8n is necessary for successful execution.

Troubleshooting

Common Issues

• Invalid Customer ID: If the provided customer ID does not exist or is malformed, the API will return an error indicating the customer could not be found.
• Missing or Incorrect Credentials: Failure to provide valid API keys or OAuth tokens will cause authentication errors.
• Validation Failures: The node performs a validation call before executing the main operation; if this fails, the node throws an error with the validation message.
• Incorrect customerData format: Since the update requires a data object with fields to update, providing incorrect or incomplete data may cause the API to reject the request.

Error Messages and Resolutions

• "N8N Tools API validation failed": Indicates the initial validation call failed. Check API key validity and permissions.
• "Cash App operation failed: <message>": Generic failure during the update operation. Review the error message for specifics, such as invalid parameters or network issues.
• "Unknown customer operation: updateCustomer": Should not occur if the operation is correctly set; indicates a possible misconfiguration or code issue.

To resolve errors, verify all input parameters, ensure credentials are correct and have sufficient permissions, and confirm the API endpoint is reachable.
