unsplash_rb

Installation

Add this line to your application's Gemfile:

gem 'unsplash'

And then execute:

$ bundle

Or install it yourself as:

$ gem install unsplash

Usage

Configuration

Before making requests, you must configure the gem with your application ID and secret. If you are using Rails, you can do this in an initializer.

Unsplash.configure do |config|
  config.application_access_key = "YOUR ACCESS KEY"
  config.application_secret = "YOUR APPLICATION SECRET"
  config.application_redirect_uri = "https://your-application.com/oauth/callback"
  config.utm_source = "alices_terrific_client_app"

  # optional:
  config.logger = MyCustomLogger.new
end

API Guidelines

All API applications must abide by the API Guidelines.

As part of the API guidelines, all API uses are required to use utm links when providing credit to photographers and Unsplash. Set the config.utm_source to your app's name to automatically append the utm source.

Public-scope actions

If you are only making public requests (i.e. nothing requiring a specific logged-in user, for example liking photos or accessing private user details), then you're ready to go!

Looking for details of a specific photo? Find it by ID:

photo = Unsplash::Photo.find("tAKXap853rY")

Want a bunch of pictures of cats? You're on the internet; of course you do.

search_results = Unsplash::Photo.search("cats")

For a complete list of available actions, see our documentation details.

User Authorization

For non-public actions, you'll have to get the user's permission to access their data. Direct them to the Unsplash authorization URL:

requested_scopes = ["public", "read_user", "something_else_you_are_asking_for"]
auth_url = Unsplash::Client.connection.authorization_url(requested_scopes)

Upon authorization, Unsplash will return to you an authentication code via your OAuth callback handler. With that you can generate an access token:

Unsplash::Client.connection.authorize!("the authentication code")

And that's it. The API actions will be available to you according to whichever permission scopes you requested and the user authorized.

Hotlinking

Hotlinking the Unsplash image files is required

Unlike most APIs, Unsplash requires for the image URLs returned by the API to be directly used or embedded in your applications (generally referred to as hotlinking). By using the CDN and embedding the photo URLs in your application, Unsplash can better track photo views and pass those stats on to the photographer, providing them with context for how popular their photo is and how it's being used.

Track Download

Do you want to trigger track download attribution on a photo ?

photo = Unsplash::Photo.find("tAKXap853rY")
photo.track_download
