  2.  Construct API Requests using POSTMAN: Select the HTTP method as “POST” and enter the API endpoint URL for the ChatGPT API. For example, if the endpoint is https://api.openai.com/v1/chat/completions, enter that URL in the request field. Click on the “Headers” tab and add the required headers. For the ChatGPT API, you need the “Content-Type” header with the value “application/json” and the “Authorization” header with the value “Bearer YOUR_API_KEY”. Replace “YOUR_API_KEY” with your actual API key. Click on the “Body” tab, select the “raw” option, and choose “JSON (application/json)” as the format. In the body, you need to provide the conversation messages in an array. Please refer below POSTMAN images.ChatGPT APIChatGPT API
