Overview
The custom n8n node for creating invoices allows users to interact with an inventory management API, specifically for generating new invoice records. This node is beneficial in scenarios where businesses need to automate the invoicing process, such as integrating with e-commerce platforms or accounting systems. For example, a user can create an invoice automatically when a sale is completed, ensuring that all necessary details are captured without manual entry.
Properties
| Name | Meaning |
|---|---|
| Customer Code | The customer code for the invoice (required). |
| Sales Order ID | The related sales order ID for the invoice (optional). |
| Invoice Details | A collection of details about the invoice, including: |
| - Invoice Number: The invoice number. | |
| - Invoice Date: The date of the invoice. | |
| - Due Date: The due date for the invoice payment. | |
| - Tax Rate: The tax rate for the invoice. | |
| - Currency: The currency for the invoice. | |
| - Comments: Comments for the invoice. | |
| Invoice Line Items | A fixed collection of line items for the invoice, allowing multiple entries, each containing: |
| - Product Code: The product code for the line item (required). | |
| - Quantity: The quantity for the line item (required). | |
| - Unit Price: The unit price for the line item. | |
| - Discount Percentage: The discount percentage for the line item. |
Output
The output of the execute() method will be structured as an array of objects, where each object contains the result of the invoice creation process. Each output object will typically include a json field that holds the response data from the API, which may contain details about the created invoice, such as its ID and status. If the node can output binary data, it would represent any associated files or documents related to the invoice.
Dependencies
- An API key credential is required to authenticate with the inventory management API.
- The node relies on external services provided by the inventory management system to create invoices.
Troubleshooting
Common issues users might encounter include:
- Missing Required Fields: If the required fields (like Customer Code or Product Code) are not provided, the node will throw an error indicating that these fields are mandatory.
- Invalid Data Types: Providing incorrect data types (e.g., a string instead of a number for Quantity) may lead to validation errors.
- API Authentication Errors: If the API key is invalid or missing, users will receive authentication-related error messages.
To resolve these issues, ensure that all required fields are filled out correctly, verify the data types of inputs, and check the validity of the API key used for authentication.
