Telnyx Oauth - Ruby
Installation
gem install telnyxSetup
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
endCommon 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).
