Google - v1.0.0

Google OAuth uses scopes to gate what your access token can do. artisanpack-ui/google lets any installed service package contribute the scopes it needs and unions them into a single consent screen — the user only sees one prompt, no matter how many packages depend on Google APIs.

The registry

ArtisanPackUI\Google\Scopes\ScopeRegistry collects three sources:

1. The baseline — always required to identify the connecting user:
   • openid
   • https://www.googleapis.com/auth/userinfo.email
   • https://www.googleapis.com/auth/userinfo.profile
2. Filter-hook contributions via ap.google.scopes.
3. Imperative registrations via ScopeRegistry::register( $scope ).

ScopeRegistry::all() returns the de-duplicated, trimmed union. Empty strings are dropped, and duplicates across the three sources are collapsed.

Registering scopes from a service package

Preferred: hook the ap.google.scopes filter in your service package's boot() method:

use ArtisanPackUI\Hooks\Facades\Filter;

class AnalyticsGoogleServiceProvider extends ServiceProvider
{
    public function boot(): void
    {
        Filter::add( 'ap.google.scopes', function ( array $scopes ): array {
            $scopes[] = 'https://www.googleapis.com/auth/analytics.readonly';
            return $scopes;
        } );
    }
}

The registry calls Filter::apply('ap.google.scopes', []) inside all(), so every hooked callback contributes to the union. The order the callbacks fire doesn't matter — the union is de-duplicated at the end.

Registering scopes from application code

For app-level scopes without a service provider:

use ArtisanPackUI\Google\Facades\Google;

Google::scopes()->register( 'https://www.googleapis.com/auth/gmail.send' );

Register from anywhere runs before an authorize URL is built — usually inside a service provider's boot().

Reading the current union

use ArtisanPackUI\Google\Facades\Google;

$scopes = Google::scopes()->all();
// ['openid', 'https://www.googleapis.com/auth/userinfo.email', ...]

Incremental consent: missing() and hasAllRequired()

When a service package is installed after a user is already connected, the registry starts returning scopes the connection doesn't hold. Two methods help you detect this:

$granted = $connection->grantedScopes();

Google::scopes()->missing( $granted );          // ['https://www.googleapis.com/auth/new-scope']
Google::scopes()->hasAllRequired( $granted );   // false

The ConnectionState view model exposes this pre-computed as missingScopes and needsReauthorize, so most callers won't touch the registry directly.

See OAuth/Reauthorize for how to build the incremental-consent URL from a granted-scope list.

Scope hygiene

Google's OAuth policies are strict about scopes:

• Only request what you use. Adding scopes you don't need triggers a verification review for external apps.
• Consent screen must list every scope. If a scope isn't in the "OAuth consent screen → Scopes" list on the Cloud Console, Google rejects the authorize request with invalid_scope at runtime. Add it there whenever a service package needs one.
• Sensitive and restricted scopes require verification. External apps that use scopes marked "sensitive" or "restricted" must complete Google's verification review before non-test-user accounts can consent.

Common scopes by service package

Refer to each service package's docs for the authoritative list.

Overriding scopes for a specific flow

OAuthManager::authorizationUrl() accepts an optional scope override:

$url = Google::oauth()->authorizationUrl(
    $user->id,
    override: [
        'openid',
        'https://www.googleapis.com/auth/analytics.readonly',
    ],
);

Useful for a "connect just for analytics" one-off flow that shouldn't require every service package's scopes. In practice this is rarely needed — the union model gets you one consent screen per user, which is almost always what you want.
