PHP Unsplash Wrapper

A PHP client for the Unsplash API.

• Official documentation
• Changelog

Installation

Unsplash-PHP uses Composer. To use it, require the library

composer require crewlabs/unsplash

Usage

Configuration

Before using, configure the client with your application ID and secret. If you don't have an application ID and secret, follow the steps from the Unsplash API to register your application.

Note that if you're just using actions that require the public permission scope, only the applicationId is required.

Crew\Unsplash\HttpClient::init([
	'applicationId'	=> 'YOUR APPLICATION ID',
	'secret'		=> 'YOUR APPLICATION SECRET',
	'callbackUrl'	=> 'https://your-application.com/oauth/callback'
]);

Authorization workflow

To access actions that are non-public (i.e. uploading a photo to a specific account), you'll need a user's permission to access their data. Direct them to an authorization URL (configuring any scopes before generating the authorization URL):

$scopes = ['public', 'write_user']
Crew\Unsplash\HttpClient::$connection->getConnectionUrl($scopes);

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

Crew\Unsplash\HttpClient::$connection->generateToken($code);

With the token you can now access any additional non-public actions available for the authorized user.

Permission Scopes

The current permission scopes defined by the Unsplash API are:

• public (Access a user's public data)
• read_user (Access a user's private data)
• write_user (Edit and create user data)
• read_photos (Access private information from a user's photos)
• write_photos (Post and edit photos for a user)
• write_likes (Like a photo for a user)
