  card_template_id: "0xd3adb00b5",
  employee_id: "123456789",
  tag_id: "DDEADB33FB00B5",
  allow_on_multiple_devices: true,

client.access_cards.resume(
  card_id: "0xc4rd1d"
)

# Unlink a card
client.access_cards.unlink(
  card_id: "0xc4rd1d"
)

Enterprise Console

Create a template

template = client.console.create_template(
  name: "Employee NFC key",
  platform: "apple",
  use_case: "employee_badge",
  protocol: "desfire",
  allow_on_multiple_devices: true,
  watch_count: 2,
  iphone_count: 3,
  design: {
    background_color: "#FFFFFF",
    label_color: "#000000",
    label_secondary_color: "#333333",
    background_image: "[image_in_base64_encoded_format]",
    logo_image: "[image_in_base64_encoded_format]",
    icon_image: "[image_in_base64_encoded_format]"
  },
  support_info: {
    support_url: "https://help.yourcompany.com",
    support_phone_number: "+1-555-123-4567",
    support_email: "support@yourcompany.com",
    privacy_policy_url: "https://yourcompany.com/privacy",
    terms_and_conditions_url: "https://yourcompany.com/terms"
  }
)

Update a template

template = client.console.update_template(
  card_template_id: "0xd3adb00b5",
  name: "Updated Employee NFC key",
  allow_on_multiple_devices: true,
  watch_count: 2,
  iphone_count: 3,
  support_info: {
    support_url: "https://help.yourcompany.com",
    support_phone_number: "+1-555-123-4567",
    support_email: "support@yourcompany.com",
    privacy_policy_url: "https://yourcompany.com/privacy",
    terms_and_conditions_url: "https://yourcompany.com/terms"
  }
)

Read a template

template = client.console.read_template(
  card_template_id: "0xd3adb00b5"
)

Get event logs

events = client.console.event_log(
  card_template_id: "0xd3adb00b5",
  filters: {
    device: "mobile", # "mobile" or "watch"
    start_date: (Time.now - 30*24*60*60).iso8601,
    end_date: Time.now.iso8601,
    event_type: "install"
  }
)

Configuration

The SDK can be configured with a custom API endpoint:

client = AccessGrid.new(
  account_id, 
  secret_key, 
  'https://api.staging.accessgrid.com' # Use a different API endpoint
)

Error Handling

The SDK throws specific errors for various scenarios:

AccessGrid::AuthenticationError - Invalid credentials
AccessGrid::ResourceNotFoundError - Requested resource not found
AccessGrid::ValidationError - Invalid parameters
AccessGrid::Error - Generic API errors

Example error handling:

begin
  card = client.access_cards.provision(
    # ... parameters
  )
rescue AccessGrid::ValidationError => e
  puts "Invalid parameters: #{e.message}"
rescue AccessGrid::Error => e
  puts "API error: #{e.message}"
end

Requirements

Ruby 2.6 or higher

Security

The SDK automatically handles:

Request signing using HMAC-SHA256
Secure payload encoding
Authentication headers
HTTPS communication

Never expose your secret_key in client-side code. Always use environment variables or a secure configuration management system.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
