+# Discover influencers in Shopify customers with influencers.club, GPT-4o and SendGrid
+
+## 1. Workflow Overview
+
+This workflow identifies potential creators or influencers among new Shopify customers, classifies them with AI, generates tailored outreach, then pushes the result into CRM, email, and Slack.
+
+It is designed for e-commerce brands that want to turn existing buyers or new account signups into creator, affiliate, ambassador, or partnership candidates.
+
+### 1.1 Entry Triggers from Shopify
+The workflow starts from two separate Shopify webhook triggers:
+- a new order event
+- a new customer creation event
+
+This allows the brand to capture both:
+- buyers with strong purchase intent
+- new signups who may still be valuable creators
+
+### 1.2 Email Extraction and Normalization
+Each trigger passes through a Set node that reduces the Shopify payload to a simplified structure containing only `email`.
+
+This block is intended to prepare a clean enrichment input, though one path is currently configured incorrectly for Shopify orders.
+
+### 1.3 Creator Enrichment
+The workflow calls the influencers.club enrichment node using the extracted email address.
+
+This enrichment attempts to identify whether the customer is a creator and returns social profile data such as platforms, followers, engagement, usernames, bios, and profile URLs.
+
+### 1.4 Routing Based on Creator Detection
+An IF node checks whether the enrichment response indicates `result.is_creator === true`.
+
+If true, the workflow continues into AI classification and outreach.  
+If false or if enrichment fails, the workflow falls back to a failure-handling branch.
+
+### 1.5 AI Classification
+A LangChain agent powered by `gpt-4o-mini` analyzes the enrichment payload and produces a structured creator classification.
+
+It determines:
+- primary platform
+- tier
+- niche and subcategory
+- follower count
+- engagement
+- value score
+- audience and brand fit reasoning
+
+### 1.6 AI Outreach Generation
+A second LangChain agent powered by `gpt-4o` creates a personalized outreach email in structured JSON.
+
+The outreach adapts to creator tier and context, acknowledging that the person is already a customer.
+
+### 1.7 Operational Outputs
+The outreach result fans out to three downstream systems:
+- HubSpot contact creation/update
+- SendGrid email delivery
+- Slack notification for high-value creators
+
+A separate Slack message is also sent for failed enrichment cases.

+
+## 4. Reproducing the Workflow from Scratch
+
+1. **Create a new workflow** in n8n and give it a name similar to:  
+   `Discover influencers by analyzing Shopify customers and executing tailored outreach`.
+
+2. **Add a Shopify Trigger node** named `Shopify Order Trigger`.
+   - Type: `Shopify Trigger`
+   - Event/topic: `orders/create`
+   - Authentication: `OAuth2`
+   - Connect Shopify OAuth2 credentials with webhook permissions for order events.
+
+3. **Add a second Shopify Trigger node** named `Shopify Customer Trigger`.
+   - Type: `Shopify Trigger`
+   - Event/topic: `customers/create`
+   - Authentication: `OAuth2`
+   - Use the same Shopify credential if appropriate.
+
+4. **Add a Set node** named `Get Order Email`.
+   - Add one field:
+     - `email` as string
+   - Recommended expression:
+     - `{{ $json.customer.email }}`
+   - This is the correct mapping for the order path.
+   - Connect `Shopify Order Trigger` → `Get Order Email`.
+
+5. **Add another Set node** named `Get Customer Email`.
+   - Add one field:
+     - `email` as string
+   - Expression:
+     - `{{ $json.email }}`
+   - Connect `Shopify Customer Trigger` → `Get Customer Email`.
+
+6. **Add the influencers.club node** named `Enrich by Email`.
+   - Type: `Influencers Club`
+   - Operation: enrich/search by email
+   - Email field:
+     - `{{ $json.email }}`
+   - Set the node to continue on error / use error output if available.
+   - Configure influencers.club API credentials.
+   - Connect both:
+     - `Get Order Email` → `Enrich by Email`
+     - `Get Customer Email` → `Enrich by Email`
+
+7. **Add an IF node** named `Is Creator?`.
+   - Condition:
+     - left value: `{{ $json.result.is_creator }}`
+     - operator: `is true`
+   - Use strict type validation if available.
+   - Connect `Enrich by Email` main success output → `Is Creator?`
+
+8. **Add a Code node** named `Handle Failed Enrichment`.
+   - Use it for the enrichment error output.
+   - Paste logic equivalent to:
+     - copy incoming email/name data
+     - mark `enrichment_status` as `failed`
+     - set creator classification to non-creator defaults
+     - add a timestamp
+   - Connect `Enrich by Email` error output → `Handle Failed Enrichment`.
+
+9. **Add a Slack node** named `Send a message - Failed Enrichment`.
+   - Operation: send message to channel
+   - Authentication: Slack OAuth2
+   - Channel: your monitoring channel, e.g. `#social-listening`
+   - Text:
+     - `Check the Newsletter Subscriber flow for {{$json.email}}`
+   - Connect `Handle Failed Enrichment` → `Send a message - Failed Enrichment`.
+
+10. **Add an OpenAI Chat Model node** named `OpenAI Classifier Model1`.
+    - Type: LangChain OpenAI Chat Model
+    - Model: `gpt-4o-mini`
+    - Temperature: `0.3`
+    - Configure OpenAI API credentials.
+
+11. **Add a Structured Output Parser node** named `Classification Output Parser1`.
+    - Schema type: manual
+    - Define a schema with root key `classification`
+    - Include fields such as:
+      - `primary_platform`
+      - `tier`
+      - `tier_name`
+      - `niche`
+      - `niche_name`
+      - `niche_subcategory`
+      - `followers`
+      - `engagement_rate`
+      - `username`
+      - `profile_url`
+      - `value_score`
+      - `content_themes`
+      - `audience_demographics`
+      - `brand_fit_score`
+      - `reasoning`
+
+12. **Add an AI Agent node** named `AI Creator Classification Agent`.
+    - Type: LangChain Agent
+    - Prompt mode: define
+    - Input text:
+      - `{{ JSON.stringify($json) }}`
+    - Add the long-form system instruction that:
+      - selects a primary platform
+      - classifies tier from follower count
+      - detects niche/subcategory
+      - calculates value score and brand fit
+      - returns valid JSON only
+    - Enable output parser.
+    - Connect:
+      - `Is Creator?` true output → `AI Creator Classification Agent`
+      - `OpenAI Classifier Model1` → AI language model port
+      - `Classification Output Parser1` → AI output parser port
+
+13. **Add a second OpenAI Chat Model node** named `OpenAI Chat Model1`.
+    - Model: `gpt-4o`
+    - Temperature: `0.8`
+    - Reuse OpenAI credentials.
+
+14. **Add another Structured Output Parser node** named `Structured Output Parser1`.
+    - Schema type: manual
+    - Root key: `outreach`
+    - Required fields:
+      - `subject`
+      - `message`
+      - `priority`
+      - `program`
+      - `offer_type`
+      - `talking_points`
+
+15. **Add another AI Agent node** named `E-Commerce Creator Outreach Agent`.
+    - Input text:
+      - `{{ JSON.stringify($json) }}`
+    - Use a system prompt that:
+      - acknowledges the person is already a customer
+      - adapts tone and offer based on creator tier
+      - outputs JSON only
+      - includes subject, message, priority, program, offer type, and talking points
+    - Enable output parser.
+    - Connect:
+      - `AI Creator Classification Agent` → `E-Commerce Creator Outreach Agent`
+      - `OpenAI Chat Model1` → AI language model port
+      - `Structured Output Parser1` → AI output parser port
+
+16. **Add a HubSpot node** named `Create or update a CRM contact`.
+    - Type: HubSpot
+    - Operation: create or update contact
+    - Authentication: App Token
+    - Use email as unique identifier.
+    - Recommended expression:
+      - `{{ $('Enrich by Email').first().json.result.email }}`
+    - Configure HubSpot app token credentials with contact read/write scopes.
+    - Optional: add mapped custom properties such as tier, niche, followers, value score, program, and priority.
+
+17. **Add a SendGrid node** named `Send an email`.
+    - Resource: mail
+    - To email:
+      - `{{ $('Enrich by Email').item.json.result.email }}`
+    - Subject:
+      - If your agent output is under `output.outreach.subject`, use that exact path.
+      - Otherwise adapt to the actual execution data, e.g. `{{ $json.outreach.subject }}`
+    - Content/body:
+      - same rule as above, e.g. `{{ $json.output.outreach.message }}` or `{{ $json.outreach.message }}`
+    - From name: your partnerships team name
+    - From email: a verified sender such as `partnerships@yourdomain.com`
+    - Configure SendGrid API credentials.
+
+18. **Add a Slack node** named `Send a message`.
+    - Operation: send channel message
+    - Channel: `#social-listening` or equivalent
+    - Build the message from creator data, for example:
+      - name from enrichment or classification
+      - email from enrichment
+      - tier and primary platform from classification
+    - Prefer expressions referencing actual existing nodes, e.g.:
+      - `{{ $('Enrich by Email').item.json.result.email }}`
+      - `{{ $('AI Creator Classification Agent').item.json.output.classification.tier }}`
+    - Configure Slack OAuth2 credentials.
+
+19. **Connect the final fan-out**:
+    - `E-Commerce Creator Outreach Agent` → `Create or update a CRM contact`
+    - `E-Commerce Creator Outreach Agent` → `Send an email`
+    - `E-Commerce Creator Outreach Agent` → `Send a message`
+
+20. **Correct broken node references before activating.**
+    - In the provided workflow JSON, several expressions reference a non-existent node named:
+      - `Influencers.club - Enrichment API by Email`
+    - Replace those references with the actual node name:
+      - `Enrich by Email`
+
+21. **Validate the actual output shape of the AI Agent nodes.**
+    - Depending on your n8n/LangChain version, parsed data may appear under:
+      - `$json.output.classification`
+      - `$json.classification`
+      - `$json.output.outreach`
+      - `$json.outreach`
+    - Run the workflow manually once and update downstream expressions accordingly.
+
+22. **Optionally improve the false branch of `Is Creator?`.**
+    - Add a node to log or notify on non-creator results.
+    - Currently only hard failures are handled; false evaluations just stop.
+
+23. **Activate the workflow.**
+    - Ensure Shopify webhooks register successfully.
+    - Test with:
+      - a Shopify test order
+      - a customer creation event
+      - a known creator email
+      - a non-creator email
+      - a malformed or missing email case

+| Main implementation risk: several downstream expressions refer to a node name that does not exist in this workflow | Replace `Influencers.club - Enrichment API by Email` with `Enrich by Email` |
+| Main data-mapping risk: the order email extraction is likely wrong | Use `{{ $json.customer.email }}` in `Get Order Email` |
+| Main routing gap: non-creators detected successfully by enrichment are not explicitly handled | Add a false-branch node after `Is Creator?` if you want logging or alternate nurturing |
