## Overview

ZoomInfo is listed in the ChatGPT app marketplace. Once connected, ChatGPT can invoke ZoomInfo tools based on your prompts or when you explicitly ask it to use ZoomInfo. Setup works on all ChatGPT tiers, including free plans.

## Setup

  **Open the Apps panel**

Click **Apps** in the ChatGPT side panel.

  **Find ZoomInfo**

Search for **ZoomInfo** and click **Connect**.

  **Authenticate**

Sign in with your ZoomInfo credentials when prompted.

  **Verify the connection**

Start a new conversation and ask: *"What ZoomInfo tools do you have access to?"*

**Next: run your first session.** Once ZoomInfo is connected, paste this into a new ChatGPT conversation. It starts from your saved GTM context and asks before it spends credits:

## Tool Behavior in ChatGPT

ChatGPT selects the appropriate ZoomInfo tool based on your request. You can guide tool selection by being specific in your prompts, or by saying "use ZoomInfo to..." followed by your request.

You can also prime ChatGPT to use ZoomInfo tools by clicking the **+** in the chat window, hovering over **More**, and selecting **ZoomInfo**. ChatGPT will still reach for ZoomInfo tools without this step, based on conversation context or if you explicitly ask.

New ZoomInfo tools become available automatically at the start of each new session.

## Troubleshooting

**Can't find the app:** open **Apps** in the side panel and search for "ZoomInfo." If it does not appear, try refreshing the page or starting a new session.

**Authentication errors:** confirm you're using your personal ZoomInfo credentials. Admin-only ZoomInfo accounts cannot authenticate to MCP.

**Credit errors:** check which credits your account has. MCP can't draw from recurring monthly credits, which some older subscriptions carry; free accounts and bulk data credits work. See [Which credits MCP uses](/docs/mcp/credits#which-credits-mcp-uses).
