How to use ChatGPT API in WordPress using the wp_remote_get function?

To use the ChatGPT API in WordPress using the wp_remote_get() function, you need to follow the steps below:

Step 1: Register for a ChatGPT API Key Before you can use the ChatGPT API, you need to register for an API key. Visit the OpenAI API website to create an account and generate an API key.

Step 2: Create a WordPress function to send a request to the ChatGPT API In your WordPress website, create a new function that will use the wp_remote_get() function to send a request to the ChatGPT API. Here’s an example function:

function get_chatgpt_response( $message ) {
    $api_key = 'YOUR_API_KEY_HERE';
    $api_url = 'https://api.openai.com/v1/engines/davinci-codex/completions';

    $data = array(
        'prompt' => $message,
        'max_tokens' => 100,
        'temperature' => 0.5,
    );

    $args = array(
        'headers' => array(
            'Content-Type' => 'application/json',
            'Authorization' => 'Bearer ' . $api_key,
        ),
        'body' => json_encode( $data ),
    );

    $response = wp_remote_post( $api_url, $args );

    if ( is_wp_error( $response ) ) {
        return false;
    }

    $body = wp_remote_retrieve_body( $response );
    $data = json_decode( $body, true );

    return $data;
}

This function takes a $message parameter that represents the text you want to send to the ChatGPT API. It uses the wp_remote_post() function to send a request to the API, passing in the API key and request data as headers and body respectively.

The function then checks for any errors in the response and returns the JSON-decoded data.

Step 3: Call the function in WordPress To use the get_chatgpt_response() function, you can simply call it from any other WordPress function or template file, passing in the message you want to send to the ChatGPT API. Here’s an example:

$response = get_chatgpt_response( 'Hello, can you help me with my WordPress website?' );

if ( $response ) {
    echo $response['choices'][0]['text'];
}

This code calls the get_chatgpt_response() function with a sample message, and if the response is successful, it displays the first response from the API in the browser.
