  { 
    link: "https://example.com/document.pdf",
    filename: "Important Document.pdf"
  },
  15551234567
);

// Template message
await whatsapp.messages.template(
  {
    name: "sample_shipping_confirmation",
    language: { code: "en_US" },
    components: [
      {
        type: "body",
        parameters: [
          { type: "text", text: "John" },
          { type: "text", text: "12345" }

    type: "button",
    body: { text: "Please select an option:" },
    action: {
      buttons: [
        { type: "reply", reply: { id: "btn1", title: "Option 1" } },
        { type: "reply", reply: { id: "btn2", title: "Option 2" } }
      ]
    }
  },
  15551234567
);

Templates API

Work with message templates:

// Get all templates
const templates = await whatsapp.template.getTemplates({
  limit: 20
});

// Create a new template
await whatsapp.template.createTemplate({
  name: "my_template",
  category: "MARKETING",
  language: "en_US",
  components: [
    {
      type: "HEADER",
      format: "TEXT",
      text: "Special Offer"
    },
    {
      type: "BODY",
      text: "Hi {{1}}, check out our latest offer: {{2}}!"
    }
  ]
});

Media API

Handle media files:

// Upload media
const mediaResponse = await whatsapp.media.uploadMedia(
  new File(['...'], 'image.jpg', { type: 'image/jpeg' })
);

// Get media details
const mediaDetails = await whatsapp.media.getMediaById(mediaResponse.id);

// Delete media
await whatsapp.media.deleteMedia(mediaResponse.id);

Error Handling

The package provides standard error handling for Meta API responses:

try {
  await whatsapp.messages.text(
    { body: "Hello world!" },
    15551234567
  );
} catch (error) {
  if (error.name === 'MetaError') {
    console.error(`Meta API Error: ${error.error.message}`);
    console.error(`Error Code: ${error.error.code}`);
    
    if (error.error.error_data) {
      console.error(`Details: ${error.error.error_data.details}`);
    }
  } else {
    console.error('Unexpected error:', error);
  }
}
