Download the PHP package predictflow/sdk without Composer

On this page you can find all versions of the php package predictflow/sdk. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.

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

PredictFlow PHP SDK

Packagist

The official PHP SDK for PredictFlow — demand forecasting, inventory intelligence, and pricing optimization for Shopify and WooCommerce stores.

Installation

Bring your own HTTP client

This SDK is built against PSR-18 (ClientInterface) and PSR-17 (request/stream factories) rather than depending on Guzzle directly. That matters most inside a WordPress/WooCommerce plugin, where you often want to reuse whatever HTTP stack is already there instead of pulling in a second one.

If you already have a PSR-18 client installed (Guzzle, Symfony HttpClient, etc.), it's discovered automatically via php-http/discovery - you don't need to configure anything. If not, install one:

Or pass your own explicitly (see examples/04_custom_http_client.php):

Quickstart

Resources

Resource Covers
$client->stores Connect/manage stores, trigger syncs, import CSV catalogs and orders
$client->products Catalog, inventory health, ABC analysis, forecasting, cost/margin, competitor prices
$client->predictions Simulation, stockout risk, and inventory policy for an existing forecast
$client->analytics KPIs, revenue trends, day-of-week seasonality, product growth, projections
$client->pricing Elasticity, optimization, simulation, cross-elasticity, batch repricing
$client->scenarios What-if scenario planning and side-by-side comparisons
$client->alerts Alert rules, templates, and evaluation history
$client->exports CSV/XLSX/PDF exports — returns a FileDownload (raw bytes + filename), not JSON

See examples/ for runnable scripts covering each of these.

Error handling

Every non-2xx response raises a specific PredictFlowException subclass, never a bare PSR-18 exception. One deliberate gap: there's no separate TimeoutException. PSR-18 doesn't standardize a portable way to distinguish "timed out" from other transport failures across different client implementations, so both surface as ConnectionException - shipping a TimeoutException that would never actually fire felt worse than not having one.

Client options

Every resource method also accepts a per-call maxRetries where relevant - e.g. pass maxRetries: 1 to opt a specific POST call into retries if you know that particular endpoint is safe to retry (see Retries below).

Retries

GET/PUT/DELETE retry automatically on 429/5xx and transport-level failures, with backoff. POST/PATCH don't, by default - they aren't guaranteed idempotent, and retrying one whose response was lost after the server already processed it (a sync trigger, a CSV import, a forecast run) risks duplicate side effects. Pass maxRetries explicitly on a specific call if you know it's safe.
