Layer::IdentityToken

Use this class to generate a token for authenticating the Layer SDK

Installation

Add this line to your application's Gemfile:

gem 'layer-identity_token'

And then execute:

$ bundle

Or install it yourself as:

$ gem install layer-identity_token

Setup

1. Create a layer app
2. Write down your provider ID (app's info tab)
3. Create a new private key (app's authentication tab – we recommend to create keys for each developer and/or environments like: staging, development)
4. Save the private key and note the key ID

Usage

token = Layer::IdentityToken.new(user_id, nonce, optional_expires_at)
token.encode

Integration

If you want to return this token as JSON and your framework (like Rails) uses #as_json you just write a controller like:

class ApiController
  def hello_layer
    token = Layer::IdentityToken.new(current_user.id, params[:nonce])

    render json: token
  end
end

Configuration

Per default the class looks for ENV variables like:

LAYER_PROVIDER_ID
LAYER_KEY_ID
LAYER_PRIVATE_KEY

If you can not set ENV variables you can also set them on the class directly:

Layer::IdentityToken.layer_provider_id = "provider_id"
Layer::IdentityToken.layer_key_id = "key_id"
Layer::IdentityToken.layer_private_key = "private_key"
