I am getting 400 Bad Request when testing API using Thunder Client

Hello @tejas-gandhi, can you give more details about your issue, where you are getting this problem in which course (course name), and which code, and share the code with us so we can help you?

Sir, the course name is "How To Create AI Tools With WordPress" on Skillshare.

Here is the complete code:

function tg_openai_generate_text_basic() {

// Get the topic from the AJAX request
$topic = $_POST['topic'];
$usage = $_POST['usage'];
$prompt = "As an expert copywriter specialized in hook generation, your task is to Generate 3 hooks for the following topic: {" . $topic . "} for using it in a: {" . $usage . "}. The output should be a Only The list of Hooks with the type.

The Hooks List:\n\n";

// OpenAI API URL and key
$api_url = 'https://api.openai.com/v1/chat/completions';
$api_key = 'sk-*****'; // OpenAI API key

// Headers for the OpenAI API
$headers = [
'Content-Type' => 'application/json',
'Authorization' => 'Bearer ' . $api_key
];

// Body for the OpenAI API
$body = [
'model' => 'gpt-3.5-turbo',
'messages' => [['role' => 'user', 'content' => $prompt]],
'temperature' => 0.7
];

// Args for the WordPress HTTP API
$args = [
'method' => 'POST',
'headers' => $headers,
'body' => json_encode($body),
'timeout' => 120
];

// Send the request
$response = wp_remote_request($api_url, $args);

// Handle the response
if (is_wp_error($response)) {
$error_message = $response->get_error_message();
wp_send_json_error("Something went wrong: $error_message");
} else {
$body = wp_remote_retrieve_body($response);
$data = json_decode($body, true);

if (json_last_error() !== JSON_ERROR_NONE) {
wp_send_json_error('Invalid JSON in API response');
} elseif (!isset($data['choices']) || !isset($data['choices'][0]['message']['content'])) {
wp_send_json_error('API request failed. Response: ' . $body);
} else {
$content = $data['choices'][0]['message']['content'];

wp_send_json($content);
}
}

// Always die in functions echoing AJAX content
wp_die();
}

add_action('wp_ajax_openai_generate_text_basic', 'tg_openai_generate_text_basic');
add_action('wp_ajax_nopriv_openai_generate_text_basic', 'tg_openai_generate_text_basic');

@tejas-gandhi I just tested it from my end I just inserted my own API key and it worked. Did you replace the API key variable with your own?

@husein sir, yes I did
