ChatGPT Agent for n8n: Manage WhatsApp, LinkedIn & Email via Nilyo

Chat with an OpenAI-powered n8n Agent to manage WhatsApp, LinkedIn, and Email through Nilyo

With this ChatGPT Agent for n8n, you can send WhatsApp messages, review recent WhatsApp conversations, look up LinkedIn profiles, and check recent emails—by chatting in the n8n interface. The agent uses your connected Nilyo accounts to take real actions and return short confirmations.

What this workflow does

• Receives your request from an n8n chat trigger.
• Understands intent with OpenAI using a chat model and conversation memory, so follow-up questions stay in context.
• WhatsApp—list recent activity: when you ask what you received recently, it calls Nilyo to list recent WhatsApp chats/messages since a date you provide.
• WhatsApp—send messages: when you ask to message someone by name or phone number, it sends the WhatsApp message via Nilyo and asks you to disambiguate if multiple matches exist. It then returns a short confirmation of what it did.
• LinkedIn—search and read profiles: when you ask to look someone up, it searches for people on LinkedIn and reads a selected LinkedIn profile.
• Email—check your inbox: when you ask to check your inbox, it lists recent emails from your connected mailbox via Nilyo.

Use cases

• Quickly follow up on leads: “Message Alex on WhatsApp” or “What did I receive recently?”
• Sales research: “Find John on LinkedIn and summarize his profile” (as read by the workflow).
• Inbox triage: “List my recent emails” without manually logging in to each service.
• Operational support for SaaS teams managing multi-channel communication.
