Overview

The WeChat Pay - Download Bill operation allows users to download transaction bills from WeChat Pay for a specified date and bill type. This node is useful for financial reconciliation, auditing, and record-keeping by retrieving detailed transaction data directly from WeChat Pay.

Typical scenarios include:

  • Automatically fetching daily or monthly transaction reports.
  • Integrating WeChat Pay billing data into accounting or ERP systems.
  • Monitoring payment success, refunds, or revoked transactions for business analysis.

For example, a merchant can schedule this node to run daily to download the previous day's transaction bill of all types ("All") and store it in their database for further processing.

Properties

Name Meaning
Bill Date The date of the bill to download, formatted as YYYYMMDD (e.g., 20230401 for April 1, 2023). Required.
Bill Type The type of bill to download. Options: "All" (ALL), "Success" (SUCCESS), "Refund" (REFUND), "Revoked" (REVOKED). Default is "All".

Output

The output JSON contains the downloaded bill data returned by the WeChat Pay API. This typically includes detailed transaction records for the specified date and bill type.

  • The exact structure depends on the WeChat Pay API response but generally includes fields such as transaction IDs, amounts, statuses, refund details, and timestamps.
  • The node does not explicitly handle binary data output for this operation; the bill data is returned as structured JSON or text content.

Dependencies

  • Requires an active subscription and valid API key credential for the external N8N Tools API service that acts as a proxy/validator for WeChat API calls.
  • Requires credentials for WeChat Pay API access configured in n8n.
  • The node internally uses a helper class (WeChatApi) to interact with WeChat Pay endpoints.
  • Network connectivity to WeChat Pay services and the N8N Tools API endpoint is necessary.

Troubleshooting

  • Invalid subscription or API key error: If the node throws an error about invalid subscription or API key, verify that the API key credential is correctly set up and has the required permissions.
  • Unsupported operation error: Ensure the operation selected is exactly "Download Bill" under the "WeChat Pay" resource.
  • Date format issues: The "Bill Date" must be provided in the correct YYYYMMDD format. Incorrect formatting may cause API errors.
  • API rate limits or network errors: Temporary failures contacting WeChat Pay or the N8N Tools API may occur. Retrying after some time or checking network/firewall settings can help.
  • Empty or malformed bill data: If the returned bill data is empty or unexpected, confirm that there were transactions on the specified date and that the bill type matches available data.
