Dropbox Php Sdk Laravel Package

Getting Started

v0.5.0 is a compatibility release, not a feature release: the only change is the composer.json constraints adding Laravel 11 support (PR #211). There are no API changes, no deprecations, and no new methods versus v0.4.2. If you are already on 0.4.x under Laravel ≤10, this is a routine bump; if you are migrating an app to Laravel 11, this is the first version of the SDK that will install cleanly alongside laravel/framework:^11.0.

Minimum path to a working call:

1. composer require kunalvarma05/dropbox-php-sdk:^0.5 — Laravel 11 pulls PHP 8.2+, so confirm your runtime before bumping.
2. Package discovery registers Kunnu\Dropbox\DropboxServiceProvider and the Dropbox facade alias automatically; there is nothing to add to config/app.php.
3. Publish the config: php artisan vendor:publish --provider="Kunnu\Dropbox\DropboxServiceProvider". On a slim Laravel 11 skeleton there is no config/dropbox.php until you do this, and every config('dropbox.*') lookup will be null otherwise.
4. Add credentials to .env and .env.example: app key/secret plus an access token (and a refresh token — see Gotchas). Dropbox app console → your app → Permissions must include files.content.write / files.content.read for anything beyond metadata, and scoped apps need the scopes set before you generate the token.
5. First use case to validate the install: push a generated report into a shared folder.

use Kunnu\Dropbox\Models\UploadArg; // argument/response models live in src/Models

$response = \Dropbox::files()->upload(
    new UploadArg('/Reports/2024-06.pdf'),
    fopen(storage_path('app/reports/2024-06.pdf'), 'rb')
);

Where to look first, in order: the GitHub README (only real documentation), src/Dropbox.php (the files(), users(), auth() entry points), src/Models (argument objects — the SDK does not take plain arrays everywhere, which is the most common first surprise), and src/Exceptions.

Implementation Patterns

Put the facade behind your own interface. The SDK has no Laravel filesystem driver, so Storage::disk('dropbox') is not available. Wrap the handful of operations you actually use (upload, download, listFolder, delete, getTemporaryLink) in a small DropboxStorage class bound in a service provider. When you eventually need to swap to the official dropbox/dropbox-sdk-php — worth considering given the release cadence — it becomes a one-class change instead of a grep across the codebase.

Resolve instances per tenant instead of relying on the singleton. The container binding is configured once from config/dropbox.php. For per-user or per-team credentials, construct the client yourself from the app key/secret and that user's stored token, or forget the resolved instance (app()->forgetInstance('dropbox')) before re-resolving. Store tokens with encrypted casts — they are bearer credentials.

Persist rotated tokens. Dropbox moved to short-lived access tokens with refresh tokens years ago; most blog posts and StackOverflow answers still assume the old long-lived tokens and will lead you into a 401 loop. After any refresh, write the new token back to storage in the same request. The SDK exposes refresh helpers on the client — verify the exact method name against src/Dropbox.php for your pinned version rather than trusting a snippet.

Queue the transfers. Uploads and downloads are synchronous HTTP calls with real latency; a 40 MB PDF on a request thread will blow past typical timeouts and tie up a PHP-FPM worker. Use a job with $timeout set well above the default, and for large files use the SDK's chunked-upload path rather than one giant request.

Paginate listings deliberately. listFolder returns a cursor and a has_more flag; a naive call silently truncates at the page size. Loop with the continue call until has_more is false, and put a hard iteration cap in so a runaway loop can't hang a queue worker.

Prefer temporary links over proxying bytes. getTemporaryLink gives you a pre-signed URL you can hand straight to the browser or an <img> tag. Proxying downloads through a controller costs you bandwidth, memory, and a PHP worker for no benefit.

Webhooks need CSRF exclusion and raw-body access. Dropbox POSTs to your endpoint with an HMAC signature over the raw body. In Laravel 11 that means $middleware->validateCsrfTokens(except: ['webhooks/dropbox']) in bootstrap/app.php, and reading $request->getContent() before any middleware mangles it. Verify the signature with the app secret and reject mismatches with a 403 before touching the payload.

Testing. Never hit the live API in CI. Mock your own interface (cheap, stable), or bind a fake into the container for the Dropbox binding. There is no built-in fake, so mocking the SDK class directly means stubbing model return types — another reason to own the interface.

Gotchas and Tips

• Read the changelog before you celebrate. v0.5.0 changes exactly one line of composer.json. If you were hoping for Laravel 11 features (or fixes), there are none. Pin ^0.5 and diff v0.4.2...v0.5.0 yourself — it takes ten seconds.
• Release cadence is the real risk. This is a community SDK whose release history has long gaps; the official Dropbox PHP SDK is the safer long-term bet for anything mission-critical. Keep the abstraction layer described above so the decision stays reversible.
• Arguments are objects, not arrays. UploadArg, CreateFolderArg and friends. Passing ['path' => ...] fails with a type error that reads like a bug in the package. Check src/Models first whenever a call "doesn't work".
• Rate limits are normal, not exceptional. Expect 429s on backfills and bulk syncs. Catch the SDK's DropboxClientException (not \Exception), inspect the error summary/code, and back off with retry() or a queued release. Mask tokens before logging any exception message.
• config:cache in deployment is mandatory and also a trap. The SDK reads config at resolution time; if you use env() anywhere outside config/dropbox.php it will silently return null once config is cached. Publish the config and keep every env() call inside it.
• Path handling. Dropbox paths are case-insensitive but case-preserving, and there is no distinction between a missing file and a missing parent folder when creating — create parents explicitly or your createFolder calls will fail on first run of a fresh environment.
• Response objects are not arrays. Upload/download/list responses are model objects with getters. Cast or map them at the boundary of your service class so the rest of your app isn't coupled to SDK internals.
• Extension points are plain PHP. DropboxApp and Dropbox are ordinary constructible classes, exceptions extend the client exception, and there are no Laravel events fired — if you want telemetry, wrap the calls in your own decorator. That is also the cheapest place to add retry/backoff and request-id logging.
• Laravel 11 housekeeping. Run php artisan about and composer why-not kunalvarma05/dropbox-php-sdk 0.5.0 when the upgrade won't resolve — it is almost always a transitive illuminate/support constraint from another package, not this one.
