FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Informations about the package sdk

selectwin/sdk (PHP)

Official Selectwin PHP SDK — payments (credit card, PIX, boleto), subscriptions, wallets, webhooks and more.

Status: early / work in progress (0.1.0). Generated core (openapi-generator, Guzzle) + a hand-written DX shell (typed exceptions, retries, idempotency, pagination, webhook verification).

Quickstart

Every resource exposes Concise aliases (create, retrieve, update, list, delete, plus verbs like $sw->subscriptions->pause('subs_…')). The full generated API is always reachable via ->raw():

Pagination

Top-level list() returns a Paginator — iterate every item across pages, grab the first page, or collect into an array:

Webhooks

Selectwin\WebhookEvents::ALL is the authoritative catalog; WebhookEvents::isValid($type) validates a value. $sw->webhooks also manages endpoints/events/dispatches.

What the SDK adds over the raw generated client

The package is a generated core (from the OpenAPI v2.0.0 spec, namespace Selectwin\Api / Selectwin\Model) + a hand-written DX shell:

Typed client — new SelectwinClient($key) → $sw->transactions, $sw->subscriptions, …
Concise aliases per resource accepting an array or a generated model; ->raw() for the full generated surface.
Typed exceptions by HTTP status / error.code: CardException (402, getDisplayMessage()/isReversible()), ValidationException (getParams()), RateLimitException (getRetryAfter()), AuthenticationException, PermissionDeniedException, NotFoundException, ConflictException, ApiErrorException, ApiConnectionException.
Auto-retries (429/5xx/network) with backoff honouring Retry-After (Guzzle handler stack).
Idempotency — an X-Idempotency-Key is added to every mutation.
Pagination — Paginator (iterate, first(), toArray(), pages()).
Webhook verification — constructEvent (HMAC-SHA256 of the raw body, constant-time).

Auth is the selectkey header; the environment (sandbox/production) is resolved from the key prefix (sk_test_ / sk_live_).

Architecture

lib/ and src/ share the Selectwin\ namespace via two PSR-4 directories. Cross-cutting concerns are injected once into the Guzzle client + Configuration, so every endpoint inherits them and new endpoints work automatically on regen.

Development

Publishing (Packagist)

Packagist serves versions straight from git tags — nothing is uploaded. One-time setup:

Sign in to https://packagist.org with GitHub and Submit the repo URL (https://github.com/selectwin/sdk-php). Packagist installs a webhook so every pushed tag becomes a new version automatically.
git tag v0.1.0 && git push origin v0.1.0.

.github/workflows/release.yml runs the test suite on each tag and (optionally, if the PACKAGIST_USERNAME / PACKAGIST_API_TOKEN secrets are set) pings Packagist to refresh immediately — otherwise it relies on the webhook.

Roadmap

Packagist release (above) once the API stabilises; a Laravel package (selectwin/laravel) on top.
