Telnyx Ruby Library

The Telnyx Ruby library provides convenient access to the Telnyx API from applications written in the Ruby language. It includes a pre-defined set of classes for API resources that initialize themselves dynamically from API responses.

The library also provides other features. For example:

• Easy configuration path for fast setup and use.
• Helpers for pagination.
• Tracking of "fresh" values in API resources so that partial updates can be executed.
• Built-in mechanisms for the serialization of parameters according to the expectations of Telnyx's API.

Documentation

See the API docs.

Installation

You don't need this source code unless you want to modify the gem. If you just want to use the package, just run:

gem install telnyx

If you want to build the gem from source:

gem build telnyx.gemspec

Requirements

• Ruby 2.1.0+

Bundler

If you are installing via bundler, you should be sure to use the https rubygems source in your Gemfile, as any gems fetched over http could potentially be compromised in transit and alter the code of gems fetched securely over https:

source'https://rubygems.org'gem'telnyx'

Usage

The library needs to be configured with your account's secret key which is available in your Telnyx Portal. Set Telnyx.api_key to its value:

require"telnyx"Telnyx.api_key="YOUR_API_KEY"# list messaging profilesTelnyx::MessagingProfile.list()# retrieve single messaging profileTelnyx::MessagingProfile.retrieve("123")

Iterating over a resource

API resources are paginated and the library comes with a handful of methods to ease dealing with them seemlessly.

# list messaging profilesfirst_page=Telnyx::MessagingProfile.list()# check whether there are more pages to go throughiffirst_page.more?puts("There are still more pages to go.")elseputs("This is the last page.")end# get current page's size and numberfirst_page.page_sizefirst_page.page_number# fetch the next and previous pagessecond_page=first_page.next_pagefirst_page=second_page.previous_page# iterate over the results of a *single page*second_page.eachdo |messaging_profile|
puts(messaging_profile.id)end# iterate over *all of the messaging profiles* starting at `first_page`# similar to `each`, but requests subsequent pages as neededfirst_page.auto_paging_eachdo |messaging_profile|
puts(messaging_profile.id)end

Configuring a Client

While a default HTTP client is used by default, it's also possible to have the library use any client supported by Faraday by initializing a Telnyx::TelnyxClient object and giving it a connection:

conn=Faraday.newclient=Telnyx::TelnyxClient.new(conn)connection,resp=client.requestdoTelnyx::MessagingProfile.retrieve("123",)endputsresp.request_id

Configuring Automatic Retries

The library can be configured to automatically retry requests that fail due to an intermittent network problem:

Telnyx.max_network_retries = 2

Configuring Timeouts

Open and read timeouts are configurable:

Telnyx.open_timeout=30# in secondsTelnyx.read_timeout=80

Please take care to set conservative read timeouts. Some API requests can take some time, and a short timeout increases the likelihood of a problem within our servers.

Logging

The library can be configured to emit logging that will give you better insight into what it's doing. The info logging level is usually most appropriate for production use, but debug is also available for more verbosity.

There are a few options for enabling it:

1. Set the environment variable TELNYX_LOG_LEVEL to the value debug or info:

   $ export TELNYX_LOG_LEVEL=info
   

2. Set Telnyx.log_level:

   Telnyx.log_level=Telnyx::LEVEL_INFO

Development

The test suite depends on telnyx-mock, so make sure to fetch and run it from a background terminal (telnyx-mock's README also contains instructions for installing via Homebrew and other methods):

go get -u github.com/telnyx/telnyx-mock
telnyx-mock

Run all tests:

bundle exec rake test

Run a single test suite:

bundle exec ruby -Ilib/ test/telnyx/util_test.rb

Run a single test:

bundle exec ruby -Ilib/ test/telnyx/util_test.rb -n /should.convert.names.to.symbols/

Run the linter:

bundle exec rake rubocop

Run guard:

bundle exec guard

Update the bundled telnyx-mock by editing the version number found in .travis.yml.

Adding a new resource

To add a new resource:

1. Add the class for the resource under lib/telnyx/.
2. Require the new class in lib/telnyx.rb.
3. Add the association between OBJECT_NAME and class name in the object_classes hash in lib/telnyx/util.rb.
4. Add tests to validate the behaviour of the new class.

Acknowledgements
