Getting started with Ruby

The source code of the Ruby SDK is hosted here: https://github.com/clerkinc/clerk-sdk-ruby

Add this line to your application's Gemfile

gem 'clerk-sdk-ruby', require: "clerk"

And then execute:

$ bundle install

Or install it yourself as:

$ gem install clerk-sdk-ruby

Quick Start

First, you need to get an API key for a Clerk instance.

This is done on the API Keys page.

Then you can instantiate a Clerk::SDK instance and access all Backend API endpoints. Here's a quick example:

.env1

Configuration

The SDK can be configured in three ways: environment variables, configuration singleton and constructor arguments. The priority goes like this:

Constructor arguments
Configuration object
Environment variables

If an argument is not provided, the configuration object is looked up, which falls back to the associated environment variable. Here's an example with all supported configuration settings their environment variable equivalents:

1
Clerk.configure do |c|
2
  c.secret_key = "your_secret_key" # if omitted: ENV["CLERK_SECRET_KEY"] - API calls will fail if unset
3
  c.base_url = "https://..." # if omitted: "https://api.clerk.dev/v1/"
4
  c.logger = Logger.new(STDOUT) # if omitted, no logging
5
  c.middleware_cache_store = Rails.cache # if omitted: no caching
6
end

You can customize each instance of the Clerk::SDK object by passing keyword arguments to the constructor:

1
clerk = Clerk::SDK.new(
2
    secret_key: "X",
3
    base_url: "Y",
4
    logger: Logger.new()
5
)

Refer to the Faraday documentation for details.

Environment variables

Here's a list of all environment variables the SDK uses:

Variable name	Usage
`CLERK_API_BASE`	Overrides the default API base URL: https://api.clerk.dev/v1/
`CLERK_API_KEY`	The Secret key of your instance (required)
`CLERK_SIGN_IN_URL`	Rails view helper: `clerk_sign_in_url`
`CLERK_SIGN_IN_UP`	Rails view helper: `clerk_sign_up_url`
`CLERK_USER_PROFILE_URL`	Rails view helper: `clerk_user_profile_url`
