Overview

This node integrates with the Cash App API to manage customers and their group memberships. Specifically, the "Add Customer to Group" operation allows you to add an existing customer to a specified customer group within your Cash App account.

This functionality is useful in scenarios where you want to organize customers into groups for targeted marketing, loyalty programs, or segmented reporting. For example, you might add VIP customers to a special group to provide exclusive offers or track their purchases separately.

Properties

Name Meaning
Customer ID The unique identifier of the customer to add to a group (e.g., customer_123456789).
Group ID The unique identifier of the group to which the customer will be added (e.g., group_123456789).

Output

The node outputs a JSON object containing the result of the add-to-group operation under the key groupMembership. This typically includes confirmation details about the customer's membership in the group as returned by the Cash App API.

Example output structure:

{
  "resource": "customer",
  "operation": "addCustomerToGroup",
  "success": true,
  "creditsUsed": 1,
  "creditsRemaining": 99,
  "groupMembership": {
    // Details about the customer's membership in the group
  }
}

No binary data output is involved in this operation.

Dependencies

  • Requires an API key credential for authenticating requests to the external Cash App API.
  • The node uses an internal helper class to interact with the Cash App API endpoints.
  • The node expects the API URL and API key to be configured in the credentials.
  • No additional environment variables are required beyond the API authentication setup.

Troubleshooting

  • Common issues:

    • Invalid or missing Customer ID or Group ID parameters will cause the operation to fail.
    • API authentication errors if the API key credential is invalid or expired.
    • Network connectivity issues preventing access to the Cash App API endpoint.

  • Error messages:

    • "N8N Tools API validation failed": Indicates that the API key or request parameters were rejected by the validation endpoint. Verify your API key and input parameters.
    • "Unknown customer operation: addCustomerToGroup": Should not occur if the operation is correctly selected; indicates a possible mismatch in resource-operation handling.
    • "Cash App operation failed: <message>": General failure message from the API call; check the detailed message for specifics.

  • Resolution tips:

    • Ensure that both Customer ID and Group ID are correctly provided and correspond to existing entities in your Cash App account.
    • Confirm that the API key credential is valid and has necessary permissions.
    • Use the node's "Continue On Fail" option to handle errors gracefully during batch processing.
