How It Works Intake and filtering - httpRequest fetches /admin/api/2024-04/products.json?limit=200&{pageinfo} - code filters only items with: - Image present - Empty bodyhtml - The currSeas:SS2025 tag - Extracts tag metadata such as x-styleCode, countryoforigin, and gender when available Pagination controller - code parses Link headers for rel="next" and extracts pageinfo - googleSheets updates ProcessingState with pageinfonext and increments the batch number for resumable polling Generation pipeline - googleSheets pulls rows with Status = Ready for AI Description; limit throttles batch size - openAi Analyze image (model gpt-4o) returns strictly visible features - lmChatOpenRouter (Claude 3.5) composes the SEO description, optionally blending verified vendor context from perplexityTool - outputParserStructured guarantees strict JSON: productid, producttitle (normalized), generateddescription, status - googleSheets writes results back to Products for review/publish Sales analytics enrichment - Schedule Trigger runs daily at 2:01 PM to capture previous day's sales - httpRequest fetches paid orders from Shopify REST API with date range filtering - splitOut and summarize nodes calculate total daily sales - Automatic Google Sheets logging with date stamps and totals - Zero-sale days are properly recorded for complete analytics continuity Reliability and insight errorTrigger routes failures to an AI agent that explains the root cause and appends a concise note to Errorlog.

Credentials Required - Shopify Access Token (Products + Orders read permissions) - OpenAI API Key (GPT-4o vision) - OpenRouter API Key (Claude Sonnet) - Perplexity API Key - Google Sheets OAuth Ideal For - E-commerce teams scaling compliant, on-brand product copy with comprehensive sales insights - Agencies and SEO specialists standardizing image-grounded descriptions with performance tracking and analytics - Stores needing resumable pagination, auditable content operations, and automated daily sales reporting in Sheets Advanced Features - Dual-workflow architecture: Content generation + Sales analytics in one system - Link-header pagination with pageinfo persistence in ProcessingState - Title/content normalization (e.g., color removal) configurable per brand - Gender-aware copywriting based on product tags - Memory windows (memoryBufferWindow) to keep multi-step prompts consistent - Melbourne timezone support for accurate daily sales cutoffs - Zero-sales handling ensures complete analytics continuity - Structured Output enforcement for downstream safety - AI-powered error diagnosis with technical and layman explanations Time & Scheduling (Universal) The workflow includes two independent schedules: - Content Generation: Every 5 minutes (configurable) for product processing - Sales Analytics: Daily at 2:01 PM Melbourne time for previous day's sales For globally distributed teams, schedule triggers and timestamps can be standardized on UTC to avoid regional drift. Pro Tip Start with small batches (limit set to 10 or fewer) to validate both copy generation and sales tracking flows. The workflow handles dual operations independently - content generation failures won't affect sales analytics and vice versa. Monitor the Errorlog sheet for any issues and use the ProcessingState sheet to track pagination progress.
