Integration Examples

​

Basic Cover Generation

async function generateCover(musicTaskId) {
  try {
    const response = await fetch('/api/v1/suno/cover/generate', {
      method: 'POST',
      headers: {
        'Authorization': 'Bearer YOUR_API_KEY',
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        taskId: musicTaskId,
        callBackUrl: 'https://yoursite.com/cover-callback'
      })
    });

    const result = await response.json();
    console.log('Cover generation started:', result.data.taskId);

  } catch (error) {
    console.error('Cover generation failed:', error);
  }
}

​

Callback Handler

app.post('/cover-callback', (req, res) => {
  const { code, data } = req.body;

  if (code === 200) {
    console.log('Cover completed:', data.coverImageUrl);
    // Update your database with the cover image URL
    updateMusicRecord(data.taskId, data.coverImageUrl);
  } else {
    console.error('Cover generation failed:', data.errorMessage);
  }

  res.status(200).json({ received: true });
});
