All examples below assume client is already initialized as shown above.

Error Handling

All API calls can fail with network errors, rate limits (429), validation errors (422), or authentication errors (401). Always handle errors in production code:

begin
  result = client.messages.send_(to: "+13125550001", from: "+13125550002", text: "Hello")
rescue Telnyx::Errors::APIConnectionError
  puts "Network error — check connectivity and retry"
rescue Telnyx::Errors::RateLimitError
  # 429: rate limited — wait and retry with exponential backoff
  sleep(1) # Check Retry-After header for actual delay
rescue Telnyx::Errors::APIStatusError => e
  puts "API error #{e.status}: #{e.message}"
  if e.status == 422
    puts "Validation error — check required fields and formats"
  end
end

Common error codes: 401 invalid API key, 403 insufficient permissions, 404 resource not found, 422 validation error (check field formats), 429 rate limited (retry with exponential backoff).

Important Notes

Phone numbers must be in E.164 format (e.g., +13125550001). Include the + prefix and country code. No spaces, dashes, or parentheses.
Pagination: Use .auto_paging_each for automatic iteration: page.auto_paging_each { |item| puts item.id }.
