Overview

This node integrates with the Cash App API to manage customer profiles and related operations. Specifically, the "Get Customer" operation retrieves detailed information about a specific customer using their unique Customer ID. This is useful in scenarios where you need to fetch up-to-date customer data for processing orders, managing accounts, or syncing customer details between systems.

Practical examples include:

  • Retrieving customer profile information before processing a payment.
  • Fetching customer details to display in a CRM dashboard.
  • Validating customer existence before updating or deleting records.

Properties

Name Meaning
Customer ID The unique identifier of the customer to retrieve (e.g., customer_123456789). This property is required to specify which customer's information should be fetched.

Output

The node outputs a JSON object containing the retrieved customer profile under the key customer. The structure typically includes all available customer details as returned by the Cash App API, such as name, contact information, and any other stored attributes.

Example output snippet:

{
  "success": true,
  "creditsUsed": 1,
  "creditsRemaining": 99,
  "resource": "customer",
  "operation": "getCustomer",
  "customer": {
    "id": "customer_123456789",
    "name": "John Doe",
    "email": "john.doe@example.com",
    "phone": "+1234567890",
    "...": "other customer fields"
  }
}

No binary data is produced by this operation.

Dependencies

  • Requires an API key credential for authenticating requests to the external Cash App API service.
  • The node uses an internal helper class to communicate with the Cash App API endpoints.
  • Proper configuration of the API URL and API key is necessary within the n8n credentials setup.

Troubleshooting

  • Common issues:

    • Invalid or missing Customer ID will cause the operation to fail.
    • Incorrect or expired API key credentials may result in authentication errors.
    • Network connectivity problems can prevent successful API calls.

  • Error messages:

    • "N8N Tools API validation failed" indicates that the API key or request parameters were rejected by the external service.
    • "Unknown customer operation: getCustomer" would occur if the operation parameter is incorrect or unsupported.
    • "Cash App operation failed: <error message>" wraps any underlying API or network error; check the message for specifics.

  • Resolutions:

    • Ensure the Customer ID is correctly provided and exists in the Cash App system.
    • Verify that the API key credential is valid and has appropriate permissions.
    • Check network access and proxy settings if applicable.
