Ruby wrapper for the Lob.com API. See the full Lob.com API Documentation. For best results, be sure that you're using the latest version of the Lob API and the latest version of the ruby wrapper. This gem gives you an ActiveRecord-style syntax to use the Lob.com API.

Supports Ruby 2.0.0 and greater.

Getting Started

Here's a general overview of the Lob services available, click through to read more.

Please read through the official API Documentation to get a complete sense of what to expect from each endpoint.

Registration

First, you will need to first create an account at Lob.com and obtain your Test and Live API Keys.

Once you have created an account, you can access your API Keys from the Settings Panel.

Installation

Add this line to your application's Gemfile:

gem 'lob'

And then execute:

$ bundle

Or manually install it yourself:

$ gem install lob

Usage

The library uses an ActiveRecord-style interface. You'll feel right at home.

For optional parameters and other details, refer to the docs here.

Initialization and Configuration

# To initialize a Lob object
lob = Lob::Client.new(api_key: "your-api-key")

# To initialize a Lob object with an older API version
lob = Lob::Client.new(api_key: "your-api-key", api_version: "2014-12-18")

Caution: Pass zero-prefixed zip codes as strings

When using zip codes with zero-prefixes, always quote them. For example when specifying 02125, pass it as a string "02125", instead of an integer.

The Ruby interpreter interprets a number with a leading zero as an octal (i.e., base-8) number and converts it to a base-10 number. Thus 01000 is converted to the base-10 value 512 (since 8*8*8=512). So not quoting might result in an entirely different zip-code than intended.

Accessing Response Headers

You can access response headers via a hidden headers method on the response hash.

addresses = lob.addresses.list

addresses._response.headers[:content_type]
# => "application/json; charset=utf-8"

addresses._response.headers[:rate_limit_window]
# => "60"

addresses._response.headers[:rate_limit_remaining]
# => "1234"

You can also access headers from Lob::InvalidRequestErrors.

begin
  lob.objects.create(name: "Test", file: "https://lob.com/test.pdf", bad_param: "bad_value")
rescue Lob::InvalidRequestError => e
  e._response.headers[:content_type]
  # => "application/json; charset=utf-8"
end

Examples

We've provided various examples for you to try out here.

There are simple scripts to demonstrate how to create all the core Lob objects (checks, letters, postcards. etc.) as well as more complex examples that utilize other libraries and external files.
