# Generate Shopify product images using Anthropic and deAPI
# Workflow Reference: E-commerce Product Visual Generator
This document provides a technical breakdown of the n8n workflow designed to automate the generation of professional product imagery for Shopify stores using Anthropic's Claude and deAPI's image generation suite.
---
### 1. Workflow Overview
The **E-commerce Product Visual Generator** is an automated pipeline that monitors a Shopify store for new products and uses AI to generate high-quality marketing visuals. It solves the problem of manual photo editing by creating both a stylized "hero" image and a clean, transparent background PNG for every new listing.
#### Logical Blocks:
* **1.1 Input Reception:** Listens for new product creation events in Shopify.
* **1.2 Data Normalization:** Extracts and formats relevant product metadata (title, category, tags).
* **1.3 AI Prompt Engineering:** Uses an AI Agent with a specialized tool to craft a high-performing image generation prompt.
* **1.4 Image Synthesis:** Generates a professional product photo based on the AI prompt.
* **1.5 Post-Processing:** Removes the background from the generated image to create a secondary asset.
* **1.6 Store Update:** Uploads both the original and the transparent images back to the specific Shopify product.

### 2. Block-by-Block Analysis
#### 2.1 Input Reception
* **Overview:** The entry point of the workflow, triggered by external store activity.
* **Nodes Involved:** `Shopify Trigger`.
* **Node Details:**
* **Type:** Shopify Trigger
* **Configuration:** Listens for the `products/create` topic.
* **Authentication:** Requires an Access Token with `read_products` scope.
* **Edge Cases:** Webhook failures if the Shopify URL is not HTTPS or if the app scopes are insufficient.
#### 2.2 Data Normalization
* **Overview:** Isolates the necessary text fields from the Shopify JSON payload to provide context for the AI.
* **Nodes Involved:** `Edit Fields`.
* **Node Details:**
* **Type:** Set / Edit Fields (v3.4)
* **Key Expressions:**
* `category`: `{{ $json.category.name }}`
* `tags`: `{{ $json.tags }}`
* **Function:** Passes through `title` and `body_html` while specifically mapping the category name and tags for clarity.
#### 2.3 AI Prompt Engineering
* **Overview:** A sophisticated AI agent cluster that transforms raw product data into a professional photography prompt.
* **Nodes Involved:** `AI Agent`, `Anthropic Chat Model`, `Image prompt booster in deAPI`, `Structured Output Parser`.
* **Node Details:**
* **AI Agent:** Uses "Define" prompt type with a System Message acting as a "Product Photography Expert."
* **Anthropic Chat Model:** Configured for `claude-sonnet-4-5-20250929`.
* **deAPI Tool:** Invokes the `prompt` resource to "boost" the text for better image generation results.
* **Structured Output Parser:** Ensures the agent returns a valid JSON object: `{"boosted_prompt": "..."}`.
* **Edge Cases:** API limits on Anthropic or deAPI; halluncinations if product descriptions are empty.
#### 2.4 Image Synthesis & Post-Processing
* **Overview:** Turns text into pixels and performs background removal.
* **Nodes Involved:** `deAPI Generate Image`, `deAPI Remove Background`.
* **Node Details:**
* **deAPI Generate Image:** Takes the `boosted_prompt` from the AI Agent and outputs a image URL.
* **deAPI Remove Background:** Takes the result of the previous node and processes it to create a transparent PNG.
* **Edge Cases:** Content moderation filters on image generation; processing timeouts for high-res images.
#### 2.5 Store Update
* **Overview:** Syncs the new visuals back to the original Shopify product listing.
* **Nodes Involved:** `Shopify Update Product`.
* **Node Details:**
* **Type:** Shopify Node (Action: Update Product).
* **Configuration:** Target `productId` is derived from the initial Trigger.
* **Image Positions:**
* **Position 1:** Styled hero image (`result_url` from deAPI Generate).
* **Position 2:** Transparent PNG (`result_url` from deAPI Remove Background).
* **Authentication:** Requires `write_products` and `write_files` scopes.

### 3. Summary Table
| Node Name | Node Type | Functional Role | Input Node(s) | Output Node(s) | Sticky Note |
| :--- | :--- | :--- | :--- | :--- | :--- |
| **Shopify Trigger** | Shopify Trigger | Webhook Entry | None | Edit Fields | 1. Shopify Product Trigger. Listens for `products/create` webhook events. |
| **Edit Fields** | Set | Data Extraction | Shopify Trigger | AI Agent | 2. Extract Product Data. Prepares category and tags for the AI Agent. |
| **AI Agent** | AI Agent | Logic Controller | Edit Fields | deAPI Generate Image | 3. AI-Powered Prompt Generation. Analyzes product data to create optimized prompts. |
| **Anthropic Chat Model** | Anthropic Model | Reasoning Engine | AI Agent | AI Agent | Part of 3. AI-Powered Prompt Generation. |
| **Image prompt booster** | deAPI Tool | Prompt Enhancer | AI Agent | AI Agent | Uses the deAPI Image Prompt Booster tool to create optimized prompts. |
| **Structured Output Parser**| Output Parser | Format Validator | AI Agent | AI Agent | Ensures consistent JSON output. |
| **deAPI Generate Image** | deAPI | Image Creation | AI Agent | deAPI Remove Background | 4. Generate Product Image. Generates a professional product image. |
| **deAPI Remove Background** | deAPI | Image Editing | deAPI Generate Image | Shopify Update Product | 5. Remove Background. Creates a transparent PNG version. |

### 4. Reproducing the Workflow from Scratch
1. **Shopify Connection:**
* Create a **Shopify Trigger** node.
* Set Topic to `products/create`.
* Authenticate using an Access Token with `read_products` scope.
2. **Data Extraction:**
* Add an **Edit Fields** node.
* Keep `title` and `body_html`.
* Add two string assignments: `category` (map to `$json.category.name`) and `tags` (map to `$json.tags`).
3. **AI Orchestration:**
* Add an **AI Agent** node. Set to "Define" prompt.
* Connect an **Anthropic Chat Model** node (select Claude 3.5 or 4.5 Sonnet).
* Connect a **deAPI Tool** node. Set resource to `prompt` and map the prompt parameter to `$fromAI`.
* Connect a **Structured Output Parser**. Define a schema with a single string property: `boosted_prompt`.
4. **Generation Pipeline:**
* Add a **deAPI** node. Operation: `generate`. Set Prompt to `{{ $json.output.boosted_prompt }}`.
* Add another **deAPI** node. Operation: `removeBackground`. This automatically uses the output of the generation node.
5. **Closing the Loop:**
* Add a **Shopify** node. Operation: `Update`.
* Map the Product ID from the Trigger node: `{{ $('Shopify Trigger').item.json.id }}`.
* In the "Images" field, add two items:
* URL 1: `{{ $('deAPI Generate Image').item.json.result_url }}`
* URL 2: `{{ $json.result_url }}` (from the Background Remover).
