Frontend Implementation

Basic Usage

// Fetch comments
const comments = await fetch(
  `${endpoint}/wp-json/headless-comments/v1/posts/${postId}/comments`,
  { headers: { 'X-API-Key': apiKey } }
).then(res => res.json());

// Submit comment
const result = await fetch(
  `${endpoint}/wp-json/headless-comments/v1/posts/${postId}/comments`,
  {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'X-API-Key': apiKey
    },
    body: JSON.stringify({
      author_name: 'John Doe',
      author_email: 'john@example.com',
      content: 'Great post!'
    })
  }
).then(res => res.json());

With reCAPTCHA v3

// 1. Check if reCAPTCHA is enabled
const config = await fetch(
  `${endpoint}/wp-json/headless-comments/v1/recaptcha/config`,
  { headers: { 'X-API-Key': apiKey } }
).then(res => res.json());

// 2. Load reCAPTCHA script (in your HTML)
// <script src="https://www.google.com/recaptcha/api.js?render=YOUR_SITE_KEY"></script>

// 3. Generate token and submit
if (config.enabled) {
  const token = await grecaptcha.execute(config.site_key, { action: 'submit' });
  // Include token in your comment submission
  body: JSON.stringify({
    author_name: 'John Doe',
    author_email: 'john@example.com',
    content: 'Great post!',
    recaptcha_token: token
  })
}
