Every action is reported to a Slack channel.**\n\n### How it works\n\nEach day the workflow fetches all unpaid invoices from iFirma using HMAC-SHA1 authenticated API calls, then enriches each invoice with full contractor details. Invoices are split into three escalation tiers based on configurable day thresholds:\n\n- **Reminder** \u2014 due today or X days before due date\n- **Pre-trial summons** \u2014 Y days after due date\n- **Court summons** \u2014 Z days after due date\n\nEach tier can independently send email, a physical letter via PostGrid, or both.\n\n### Setup\n1. Fill out the **Configuration** node with your iFirma login, API key (found under *Data and Configuration \u2192 Extensions and Integrations \u2192 API*), and the X/Y/Z day thresholds\n2. Fill out **Your Company Details** \u2014 used in letter and email templates and as the PostGrid sender address\n3. Configure PostGrid auth in both PostGrid nodes using Custom Auth:\n```json\n{ \"headers\": { \"x-api-key\": \"\" } }\n```\n\n### How to customize\nThe **Payment Reminder**, **Pre-trial summon Reminder**, and **Summons to court Reminder** nodes each have `Send by Traditional Mail` and `Send by Email` toggles \u2014 flip these to control delivery channel per escalation tier. HTML templates can be freely edited in the corresponding **Prepare Mail and Letter HTML Contents** nodes.\n\n\n\n\n\n\n\n\n\n\nNeed help?
