Track Pennylane invoice payment status with Slack notifications Workflow Solution

Workflow overview

Why this workflow matters

Useful for software delivery and engineering operations. Relevant for managed services and support workflows.

Who is this for Teams using Pennylane (French accounting platform) who want automatic alerts when invoices are paid or become overdue, without checking Pennylane manually. What it does This workflow runs every 15 minutes, fetches all customer invoices from Pennylane, and classifies them as paid, overdue, or upcoming. If any invoices have been paid or are overdue, it sends a summary notification to Slack. If everything is normal, the workflow ends silently. How to set up Import this workflow into AlekSystem Create a Header Auth credential with name Authorization and value Bearer <YOUR_PENNYLANE_TOKEN> Select your Slack channel in the SL Send Notification node Adjust the schedule interval in the Schedule Trigger node if needed Requirements Pennylane account with API access (Essentiel plan or higher) Pennylane API token with scope: customer_invoices:all (Optional) Slack workspace for notifications How to customize Change the polling interval in the Schedule Trigger node (default: every 15 minutes) Replace Slack with Telegram, Email, or any other notification channel Note: Pennylane API does not support filtering by status or paid fields, all classification is done client-side in a Code node Part of a 3-workflow billing automation suite: https://github.com/Gauthier-Huguenin/AlekSystem-pennylane-auto-invoicing
