Shopify Tracking Chatbot Integration

I have an n8n workflow that already routes customer queries through several AI agents. The last missing piece is a Logistics Agent that can pull tracking details from my Shopify store and feed them back to the user whenever they ask for an update in our text-based chat.

Here is where I’m at:
• n8n is installed on my own server and fully operational.
• The conversational flow, intent detection, and response formatting are done.
• Shopify’s Custom API access (private app credentials) is ready, but my current call only returns a 403.

What I need from you:
1. Build or correct the API call that fetches the order’s tracking details (carrier, tracking number, URL, delivery status) from Shopify. REST Admin or GraphQL Admin API—whichever is faster is fine.
2. Plug that call into the existing Logistics Agent node in n8n so the agent can answer on-demand requests like “Where’s my order #1234?”
3. Return the data in a clean JSON structure that the response-generation agent can transform into plain English for the customer.
4. Provide brief setup notes so I can replicate the solution in staging.

Success looks like: when I type “track 1234” in the chat, the bot instantly replies with the latest carrier status pulled live from Shopify. No voice capability is needed; everything remains text-based.

If you’ve connected n8n to Shopify before and can troubleshoot custom endpoints quickly, I’d love your help finishing this off.

I want to learn to do this, so share screen in process is a must.
