Loops Ruby SDK

Introduction

This is the official Ruby SDK for Loops, an email platform for modern software companies.

Installation

Install the gem and add it to the application's Gemfile like this:

bundle add loops_sdk

If bundler is not being used to manage dependencies, you can install the gem like this:

gem install loops_sdk

Usage

You will need a Loops API key to use the package.

In your Loops account, go to the API Settings page and click Generate key.

Copy this key and save it in your application code (for example, in an environment variable).

See the API documentation to learn more about rate limiting and error handling.

In an initializer, import and configure the SDK:

require "loops_sdk"

LoopsSdk.configure do |config|
  config.api_key = 'your_api_key'
end

begin

  response = LoopsSdk::Transactional.send(
    transactional_id: "closfz8ui02yq......",
    email: "[email protected]",
    data_variables: {
      loginUrl: "https://app.domain.com/login?code=1234567890"
    }
  )

  render json: response

rescue LoopsSdk::APIError => e
  # Do something if there is an error from the API
end

Handling rate limits

You can use the check for rate limit issues with your requests.

You can access details about the rate limits from the limit and remaining attributes.

begin

  response = LoopsSdk::Contacts.update(
    email: "[email protected]"
  )

  render json: response

rescue LoopsSdk::RateLimitError => e
  Rails.logger.error("Rate limit exceeded (#{e.limit} requests per second)")
  # Code here to re-try this request
rescue LoopsSdk::APIError => e
  # Handle other errors
end

Default contact properties

Each contact in Loops has a set of default properties. These will always be returned in API results.

id
