Instagram DM sales assistant for an online shoe store
We built this assistant for an online shoe store that sells largely through Instagram. Every incoming DM is passed to n8n by webhook, where a shop assistant agent answers questions about prices, sizes and colors, reserves a pair when asked and walks the customer through confirming the order, then sends the reply back to Instagram.

The work
How the automation works
1.The n8n workflow: an Instagram DM webhook, a shop assistant agent with Groq and memory, and an HTTP request that sends the reply.
Project brief
Deliverables
- Webhook endpoint for Instagram DMs
- Shop assistant agent with store instructions
- Conversation memory per customer
- Reply step through the Instagram messaging API
The challenge
Shoppers on Instagram expect quick answers in DMs. When a store owner replies hours later to a question about price or size, the customer has often moved on, and every reservation and order confirmation is typed by hand.
Our approach
A webhook receives each new DM. A shop assistant AI agent running on a Groq chat model reads the message, with simple memory so it keeps track of the conversation, such as the size and model the customer has already picked. The agent's instructions cover the store's products, prices, payment options and order steps. An HTTP request then sends the reply back to the customer through Instagram's messaging API.
The outcome
Customers now get instant replies in Instagram DMs with prices and available sizes, and the assistant can reserve a pair and confirm the order before a person steps in to handle payment and shipping.

We set up the webhook for incoming DMs and the HTTP request that sends replies.
Step 03
Build the agent
We configured the Groq agent with memory and instructions for reservations and order confirmation.
Step 04
Test conversations
We ran full test chats from first question to confirmed order and tuned the replies.

Why this project matters
In social selling, the store that answers first usually gets the sale, and an assistant that replies in seconds keeps buyers in the conversation.
Questions about this project
Can it check live stock from my store?
Yes. We can connect the agent to your product catalog or inventory, for example Shopify or a Google Sheet, so it answers from current stock.
Can you build something similar for my business?
Yes. We adapt the workflow to your tools and process, for Instagram, Facebook Messenger or WhatsApp, and give you a fixed quote after a short call.
