Email

Send emails using the SendLayer client:

require 'sendlayer'

sendlayer = SendLayer::SendLayer.new('your-api-key')

# Simple email
response = sendlayer.emails.send(
  from: 'sender@example.com',
  to: 'recipient@example.com',
  subject: 'Welcome!',
  text: 'Welcome to our platform!'
)

# HTML email with sender name
response = sendlayer.emails.send(
  from: { email: 'sender@example.com', name: 'Paulie Paloma' },
  to: 'recipient@example.com',
  subject: 'Welcome!',
  html: '<h1>Welcome!</h1><p>Welcome to our platform!</p>'
)

# Complex email with multiple recipients and attachments
response = sendlayer.emails.send(
  from: { email: 'sender@example.com', name: 'Sender' },
  to: [
    { email: 'recipient1@example.com', name: 'Recipient 1' },
    { email: 'recipient2@example.com', name: 'Recipient 2' }
  ],
  subject: 'Complex Email',
  text: 'Plain text fallback',
  html: '<p>This is a <strong>test email</strong>!</p>',
  cc: [{ email: 'cc@example.com', name: 'CC' }],
  bcc: [{ email: 'bcc@example.com', name: 'BCC' }],
  reply_to: [{ email: 'reply@example.com', name: 'Reply' }],
  attachments: [
    { path: 'path/to/file.pdf', type: 'application/pdf' }
  ],
  headers: { 'X-Custom-Header' => 'value' },
  tags: ['tag1', 'tag2']
)

Events

require 'sendlayer'
require 'time'

sendlayer = SendLayer::SendLayer.new('your-api-key')

# Get all events
all_events = sendlayer.events.get
puts "Total events: #{all_events['TotalRecords']}"

# Get filtered events (last 24 hours, opened)
end_time = Time.now
start_time = end_time - (24 * 60 * 60) # 24 hours ago

filtered_events = sendlayer.events.get(
  start_date: start_time,
  end_date: end_time,
  event: 'opened'
)

puts "Filtered events: #{filtered_events['TotalRecords']}"

Webhooks

require 'sendlayer'

sendlayer = SendLayer::SendLayer.new('your-api-key')

# Create a webhook
webhook = sendlayer.webhooks.create(
  url: 'https://your-domain.com/webhook',
  event: 'open'
)
puts "Webhook created: #{webhook['WebhookID']}"

# Get all webhooks
webhooks = sendlayer.webhooks.get
puts "Webhooks: #{webhooks}"

# Delete a webhook
sendlayer.webhooks.delete(123)

Error Handling

The SDK provides specific exception types for different error scenarios:

require 'sendlayer'

begin
  response = sendlayer.emails.send(
    from: 'sender@example.com',
    to: 'recipient@example.com',
    subject: 'Test Email',
    text: 'This is a test email'
  )
rescue SendLayer::SendLayerAPIError => e
  puts "API error: #{e.message} (Status: #{e.status_code})"
rescue SendLayer::SendLayerValidationError => e
  puts "Validation error: #{e.message}"
rescue SendLayer::SendLayerAuthenticationError => e
  puts "Authentication error: #{e.message}"
rescue SendLayer::SendLayerError => e
  puts "SendLayer error: #{e.message}"
rescue => e
  puts "Unexpected error: #{e.message}"
