Shopify Return Automation with GPT-4o, Shiprocket & WhatsApp

Automate Shopify returns end-to-end—using GPT-4o vision, Shiprocket reverse pickups, and WhatsApp

This n8n workflow turns messy return requests into a structured decision pipeline: it collects photos via an n8n form, verifies eligibility in Shopify, evaluates evidence with OpenAI (gpt-4o) vision, then routes approvals/declines through WhatsApp, Gmail, or Slack—while logging everything to Google Sheets and booking Shiprocket reverse pickups.

What this workflow does

• Collects return requests through an n8n form submission (order details, reason, and uploaded photos).
• Checks return eligibility in Shopify using policy rules, including delivery status, return window, non-returnable tags, duplicate/repeat-return flags, and a returns log stored in Google Sheets.
• Verifies photos with OpenAI GPT-4o by sending up to four uploaded photos plus the customer claim for a structured result and confidence score.
• Decides the outcome by combining policy checks, order/value thresholds, and the AI photo-verification result.
• Routes resolution paths:
  • If eligible: sends exchange/store-credit/refund choice links to the customer via WhatsApp and Gmail.
  • If manual review is needed: sends the case to Slack for agent approval/rejection with decision links.
  • If ineligible/policy-rejected: notifies the customer via Gmail.
• Validates one-time decision tokens against the Google Sheets record when customers/agents click links, then records the decision or continues the chosen resolution.
• Books reverse pickups in Shiprocket after approval and proceeds with the selected resolution, including handling store-credit outcomes.

Use cases

• Reduce return-processing time by auto-screening Shopify orders before contacting customers.
• Speed up approvals using Slack agent review only when AI + policy checks indicate uncertainty.
• Standardize return evidence review using GPT-4o vision to assess uploaded photos.
