Overview

This node interacts with a financial ledger system's Purchase Operation API specifically for India. The "List Vouchers" operation allows users to retrieve a list of purchase-related vouchers filtered by type and other criteria. This is useful for accounting, auditing, or financial reporting workflows where you need to fetch payment, expense, or salary vouchers programmatically.

Practical examples include:

  • Automatically fetching recent expense vouchers for reconciliation.
  • Listing payment vouchers within a date range for audit trails.
  • Retrieving salary vouchers sorted by amount for payroll analysis.

Properties

Name Meaning
Voucher Type Select the type of voucher to list. Options: Payment Voucher, Expense Voucher, Salary Voucher.
Limit Maximum number of vouchers to return in one request (pagination size).
Filters Optional filters to refine the voucher list:
  From Date Start date to filter vouchers from (date only, no time).
  To Date End date to filter vouchers up to (date only, no time).
  Order By Sort order of the results: Ascending or Descending.
  Order Column Field to sort by: Voucher Number, Payment Date, or Amount.

Output

The node outputs JSON data representing the list of vouchers matching the specified criteria. Each item in the output array corresponds to a voucher with its details such as voucher number, payment date, amount, and other relevant fields provided by the API.

If the API supports binary data for vouchers (e.g., PDF copies), it would be included in the binary output field, but based on the static code and properties, this node primarily returns structured JSON data about vouchers.

Dependencies

  • Requires an API key credential and user authentication (email and password) to access the ledger service.
  • The node makes HTTP requests to the ledger API endpoints, including login and voucher listing.
  • Proper configuration of the API URL and credentials in n8n is necessary.
  • No additional external services are required beyond the ledger API.

Troubleshooting

  • Authentication Failures: If the node fails to authenticate, check that the API key, email, and password credentials are correct and have sufficient permissions.
  • Empty Results: Ensure that the filters (dates, voucher type) are set correctly and that there are vouchers available matching those criteria.
  • API Rate Limits or Timeouts: Large limits or complex filters might cause slow responses or rate limiting. Try reducing the limit or simplifying filters.
  • Invalid Filter Values: Using unsupported values for order column or voucher type may cause errors. Use only the provided options.
  • Network Issues: Verify network connectivity to the ledger API endpoint.

Common error messages will typically indicate authentication failure or invalid parameters. Resolving them involves verifying credentials and input property values.
