Migration: Text Editor SDK to REST APIs

  <textarea></textarea>
</grammarly-editor-plugin>

After (Current REST APIs)

// Server-side scoring replaces client-side editor integration
async function scoreContent(text: string) {
  const token = await getAccessToken();
  const response = await fetch('https://api.grammarly.com/ecosystem/api/v2/scores', {
    method: 'POST',
    headers: { 'Authorization': `Bearer ${token}`, 'Content-Type': 'application/json' },
    body: JSON.stringify({ text }),
  });
  return response.json();
}
