1. COMPOSER

composer require akkyoh/socialite_bitbucket

2. SERVICE PROVIDER

• Remove Laravel\Socialite\SocialiteServiceProvider from your providers[] array in config\app.php if you have added it already.
• Add \SocialiteProviders\Manager\ServiceProvider::class to your providers[] array in config\app.php.

// For example
'providers' => [
    // a whole bunch of providers
    // remove 'Laravel\Socialite\SocialiteServiceProvider',
    \SocialiteProviders\Manager\ServiceProvider::class, // add
];

• If you would like to use the Socialite Facade, you need to install it.

3. ADD THE EVENT AND LISTENERS

• Add SocialiteProviders\Manager\SocialiteWasCalled event to your listen[] array in <app_name>/Providers/EventServiceProvider.
• Add your listeners (i.e. the ones from the providers) to the SocialiteProviders\Manager\SocialiteWasCalled[] that you just created.
• The listener that you add for this provider is 'Akkyoh\SocialiteBitbucket\BitbucketExtendSocialite@handle',.
• Note: You do not need to add anything for the built-in socialite providers unless you override them with your own providers.

// For example
protected $listen = [
    \SocialiteProviders\Manager\SocialiteWasCalled::class => [
        // add your listeners (aka providers) here
        'Akkyoh\SocialiteBitbucket\BitbucketExtendSocialite@handle',
    ],
];

4. ENVIRONMENT VARIABLES

If you add environment values to your .env as exactly shown below, you do not need to add an entry to the services array.

// other values above
BITBUCKET_KEY=yourkeyfortheservice
BITBUCKET_SECRET=yoursecretfortheservice
BITBUCKET_REDIRECT_URI=https://example.com/login

You do not need to add this if you add the values to the .env exactly as shown above. The values below are provided as a convenience in the case that a developer is not able to use the .env method

'bitbucket' => [
    'client_id' => env('BITBUCKET_KEY'),
    'client_secret' => env('BITBUCKET_SECRET'),
    'redirect' => env('BITBUCKET_REDIRECT_URI'),
],

You should now be able to use it like you would regularly use Socialite (assuming you have the facade installed):

return Socialite::driver('bitbucket') -> redirect();
