Discover the Next-Level Virtual Agent: Integrating GPT-3 API with ServiceNow! 🤖✨

🔎 What is GPT-3 API? Unleash the power of GPT-3 (Generative Pre-trained Transformer 3) API and elevate your ServiceNow virtual agent's capabilities to a whole new level. 🌐🧠

💡 Step-by-Step Integration Guide: Learn how to seamlessly integrate GPT-3 API with your ServiceNow platform. Follow our comprehensive step-by-step guide to enable natural language processing and advanced conversational interactions. 🚀

• 📌 Step 1: Create GPT account and access to developer UI https://platform.openai.com/docs/api-reference/making-requests
  Note: The Script in this article may be different if GPT changes their API in the future version
  
• 📌 Step 2: Set Up REST Message with below details:
  Note: Authorization should be  Bearer YOUR_API_KEY - This can be found under your profile image
  
  

Build your POST Method with below content:

{
     "model": "gpt-3.5-turbo",
     "messages": [{"role": "user", "content": "${content}"}],
     "temperature": 0.7
}

📌 Step 3: Build your simple Flow for Virtual Chat.

In the script, you will trigger the REST we built eariler with input from user

try {
		var question = vaInputs.question;
		gs.info('Async Chat '+ responseBody)
		var r = new sn_ws.RESTMessageV2('ChatGPT', 'POST');//give your rest mesage name and method name
		r.setStringParameterNoEscape('content', question);//give your field name

		var response = r.execute();
		var responseBody = response.getBody();//it will give the response body
		var code = response.getStatusCode();//get status code

		var responseObj = JSON.parse(responseBody);
		vaVars.u_request = r.getRequestBody();//it will give the request body
		vaVars.u_response = responseBody;
		vaVars.u_status_code = code;
		var u_answer = responseObj.choices[0].message.content+'';//it will give the text from response
		vaVars.u_answer = u_answer;
	

	} catch (ex) {
		var message = ex.message;
	}

Note: Don't forget to train your Bot NLU so that it can realize the conversation entry.

Now it is ready to ask GPT
