README
This library is a PHP 7.4 implementation of the Discogs API v2.0. The Discogs API is a REST-based interface. By using this library you don't have to worry about communicating with the API: all the hard work has already be done.
This API is build upon the shoulders of a giant: Guzzle 7.0. This is an absolutely awesome library.

Installation
Start by installing composer. Next do:
$ composer require tafoyaventures/php-discogs-api
Requirements
PHP >=7.4.0
Usage
Creating a new instance is as simple as:
<?php $client = Discogs\ClientFactory::factory([]);
User-Agent
Discogs requires that you supply a User-Agent. You can do this easily:
<?php $client = Discogs\ClientFactory::factory([ 'headers' => ['User-Agent' => 'your-app-name/0.1 +https://www.awesomesite.com'], ]);
Throttling
Discogs doesn't like it when you hit their API at a too high connection rate. Use the ThrottleSubscriber
to
prevent getting errors or banned:
<?php $handler = \GuzzleHttp\HandlerStack::create(); $throttle = new Discogs\Subscriber\ThrottleSubscriber(); $handler->push(\GuzzleHttp\Middleware::retry($throttle->decider(), $throttle->delay())); $client = Discogs\ClientFactory::factory(['handler'=>$handler]);
Authentication
Discogs API allow to access protected endpoints with either a simple Discogs Auth Flow or a more advanced (and more complex) Oauth Flow
Discogs Auth
As stated in the Discogs Authentication documentation:
In order to access protected endpoints, you’ll need to register for either a consumer key and secret or user token, depending on your situation:
- To easily access your own user account information, use a User token.
- To get access to an endpoint that requires authentication and build 3rd party apps, use a Consumer Key and Secret.
With the Discogs Php API you can add your credentials to each request by adding a query
key to your own defaults like this:
Instead of query
use Authorization
header
$client = ClientFactory::factory([ 'headers' => [ 'Authorization' => "Discogs key=key_here, secret=secret_here", ], ]);
Authenticate with Personal access token, you can get it from https://www.discogs.com/settings/developers
$client = ClientFactory::factory([ 'headers' => [ 'User-Agent' => $user_agent, 'Authorization' => "Discogs token={$access_token}", ] ]);
OAuth
There are a lot of endpoints which require OAuth. Lucky for you using Guzzle this is peanuts. If you're having trouble obtaining the token and token_secret, please check out my example implementation.
<?php $oauth = new GuzzleHttp\Subscriber\Oauth\Oauth1([ 'consumer_key' => $consumerKey, // from Discogs developer page 'consumer_secret' => $consumerSecret, // from Discogs developer page 'token' => $token['oauth_token'], // get this using a OAuth library 'token_secret' => $token['oauth_token_secret'] // get this using a OAuth library ]); $handler = GuzzleHttp\HandlerStack::create(); $handler->push($oauth); $client = Discogs\ClientFactory::factory([ 'handler' => $handler, 'auth' => 'oauth' ]);
History
Another cool plugin is the History plugin:
<?php $container = []; $history = GuzzleHttp\Middleware::History($container); $handler = GuzzleHttp\HandlerStack::create(); $handler->push($history); $client = Discogs\ClientFactory::factory([ 'handler' => $handler ]); $response = $client->search([ 'q' => 'searchstring' ]); foreach ($container as $row) { print $row['request'] -> getMethod(); // GET print $row['request'] -> getRequestTarget(); // /database/search?q=searchstring print strval($row['request'] -> getUri()); // https://api.discogs.com/database/search?q=searchstring print $row['response'] -> getStatusCode(); // 200 print $row['response'] -> getReasonPhrase(); // OK }
More info and plugins
For more information about Guzzle and its plugins checkout the docs.
Perform a search:
Per august 2014 a signed OAuth request is required for this endpoint.
<?php $response = $client->search([ 'q' => 'Meagashira' ]); // Loop through results foreach ($response['results'] as $result) { var_dump($result['title']); } // Pagination data var_dump($response['pagination']); // Dump all data var_dump($response->toArray());
Get information about a label:
<?php $label = $service->getLabel([ 'id' => 1 ]);
Get information about an artist:
<?php $artist = $service->getArtist([ 'id' => 1 ]);
Get information about a release:
<?php $release = $service->getRelease([ 'id' => 1 ]); echo $release['title']."\n";
Get information about a master release:
<?php $master = $service->getMaster([ 'id' => 1 ]); echo $master['title']."\n";
Get image
Discogs returns the full url to images so just use the internal client to get those:
$release = $client->getRelease([ 'id' => 1 ]); foreach ($release['images'] as $image) { $response = $client->getHttpClient()->get($image['uri']); // response code echo $response->getStatusCode(); // image blob itself echo $client->getHttpClient()->get($image['uri'])->getBody()->getContents(); }
User Collection
Authorization is required when folder_id
is not 0
.
Get collection folders
<?php $folders = $service->getCollectionFolders([ 'username' => 'example' ]);
Get collection folder
<?php $folder = $service->getCollectionFolder([ 'username' => 'example', 'folder_id' => 1 ]);
Get collection items by folder
<?php $items = $service->getCollectionItemsByFolder([ 'username' => 'example', 'folder_id' => 3 ]);
Listings
Creating and manipulating listings requires you to be authenticated as the seller
Create a Listing
<?php $response = $client->createListing([ 'release_id' => '1', 'condition' => 'Good (G)', 'price' => 3.49, 'status' => 'For Sale' ]);
Change Listing
<?php $response = $client->changeListing([ 'listing_id' => '123', 'condition' => 'Good (G)', 'price' => 3.49, ]);
Delete a Listing
<?php $response = $client->deleteListing(['listing_id' => '123']);
Create Listings in bulk (via CSV)
<?php $response = $client->addInventory(['upload' => fopen('path/to/file.csv', 'r')]); // CSV format (example): // release_id,condition,price // 1,Mint (M),19.99 // 2,Near Mint (NM or M-),14.99
Delete Listings in bulk (via CSV)
<?php $response = $client->deleteInventory(['upload' => fopen('path/to/file.csv', 'r')]); // CSV format (example): // listing_id // 123 // 213 // 321
