Step-by-Step: How to Build an AI Agent with AgentKit

Let’s walk through how a digital marketer or business team could build their first agent.

Step 1: Set Up Your Account

  • Log into your OpenAI Platform Dashboard.
  • Access the Agent Builder (beta) section under AgentKit.

Step 2: Define Your Agent’s Goal

Ask yourself:

“What specific problem do I want to automate?”

Examples:

  • Qualify new leads based on form submissions.
  • Answer FAQs from the website chat.
  • Generate personalized ad copy from product data.

Step 3: Create a New Agent Workflow

In the Agent Builder canvas, add nodes like:

  • “Receive Message”
  • “Extract Keywords”
  • “Search Product Catalog”
  • “Respond with Summary”

Each node can have its own prompt, context, and guardrails.

Step 4: Add Tools & Connectors

Connect APIs or tools — for example:

  • Google Sheets: fetch campaign data
  • HubSpot CRM: log leads
  • Slack: send team alerts

Step 5: Embed ChatKit

Copy the HTML embed code from your AgentKit dashboard and paste it into your website.

Step 6: Test & Evaluate

Use the Preview button to simulate real conversations.
Then run Evals to measure how well your agent performs — OpenAI grades it on response accuracy, helpfulness, and reliability.
