Sendgo ships 20 official packages. The rule is short:

1. If there is a package for your framework, use it — the configuration and DI wiring are already done.
2. Otherwise use the core package for your language.
3. From the browser or a mobile app, do not call Sendgo directly — go through your own server.

Server core SDKs

Framework-agnostic clients. They work anywhere.

Language	Package	Install	Guide
PHP	sendgo/php	composer require sendgo/php	PHP
Node.js / TypeScript	@sendgo/node	npm install @sendgo/node	Node.js
Python	sendgo-python	pip install sendgo-python	Python
Go	github.com/send-go/go	go get github.com/send-go/go	Go
Java	io.sendgo:sendgo-java	Maven Central	Java
Ruby	sendgo	gem install sendgo	Ruby
C# / .NET	Sendgo.SDK	dotnet add package Sendgo.SDK	.NET

Framework extensions

A core package plus configuration, service registration and dependency injection. The core comes with it.

Framework	Package	Built on	What you get
Laravel	sendgo/laravel	sendgo/php	Auto-discovered ServiceProvider, Facade, publishable config, notification channel
Symfony	sendgo/symfony	sendgo/php	Bundle, DI extension, services.yaml configuration
WordPress / WooCommerce	sendgo/wordpress	sendgo/php	Settings screen, order status hooks
NestJS	@sendgo/nestjs	@sendgo/node	SendgoModule.forRoot(), SendgoService
Django	sendgo-django	sendgo-python	settings.SENDGO, app-ready initialisation
FastAPI	sendgo-fastapi	sendgo-python	SendgoDep dependency, pydantic settings
Spring Boot	io.sendgo:sendgo-spring	io.sendgo:sendgo-java	Auto-configuration, application.yml binding
Ruby on Rails	sendgo-rails	sendgo	Railtie, sendgo:install generator
ASP.NET Core	Sendgo.AspNetCore	Sendgo.SDK	services.AddSendgo(...) DI

Frontend and mobile

These assume a server in front. Do not ship keys in a client bundle.

Target	Package	How to use it
React / Next.js	@sendgo/react	Call @sendgo/node from a Route Handler; the client calls that route
Vue / Nuxt	@sendgo/vue	Call from a Nuxt server route
Flutter / Dart	sendgo_flutter	Go through your own backend; no keys in the app

Nothing fits

Call the REST API. The spec is public.
