Telnyx Oauth - Ruby

Installation

gem install telnyx

Setup

require "telnyx"

client = Telnyx::Client.new( api_key: ENV["TELNYX_API_KEY"], # This is the default and can be omitted )

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

Pagination: Use .auto_paging_each for automatic iteration: page.auto_paging_each { |item| puts item.id } .
