Stripe Dispute Tracker with OpenAI Rebuttal & Slack Alerts (n8n)

Fight Stripe disputes faster—automatically draft facts-only rebuttals with OpenAI and alert your team in Slack

This n8n workflow monitors Stripe dispute events, checks upcoming evidence deadlines daily, generates a facts-based OpenAI rebuttal letter, updates the dispute evidence in Stripe (draft or submit/accept), and sends clear Slack notifications for both actions and outcomes.

What this workflow does

• Triggers on Stripe disputes when Stripe sends dispute events (created/closed) or on a daily morning schedule.
• On dispute creation, fetches full dispute details from Stripe, including the charge context (e.g., the charge, refunds, and payment intent) and pulls the customer’s recent charge history when available.
• Applies rule-based logic to decide whether to fight, accept, or take no action, then compiles the Stripe-backed facts and evidence fields needed for a response.
• When fighting, uses OpenAI to draft a rebuttal letter strictly from the provided facts. If the model output includes unsupported details, it falls back to a prebuilt facts-only letter.
• Updates Stripe by saving evidence as a draft or submitting it to the bank based on your settings, and posts a detailed dispute status update to Slack.
• Each morning, lists open disputes approaching their evidence deadline and posts a consolidated warning in Slack.
• When Stripe closes a dispute, formats the outcome and posts a closure update to Slack.

Use cases

• Reduce chargeback loss by responding to Stripe disputes consistently and on time.
• Centralize dispute status visibility for finance teams with Slack alerts.
• Automate evidence preparation using Stripe data—without relying on manual copy/paste.
