# SDKs
{% hint style="info" %}
Are you missing an SDK? Feel free to contribute one, and we will reward you with a lifetime license for creating and maintaining the library.
{% endhint %}
{% hint style="success" %}
Using Laravel, Magento or PrestaShop? There are ready-made [packages](/introduction/packages/packages.md) for those, so you don't need to write the integration yourself.

PHP
A general PHP library that can be used in any PHP product.
**Official:**
* **Source**:
* **Packagist**:
```bash
composer require justpush/justpush-php-sdk
```
```php
$response = JustPushMessage::token('YOUR_API_TOKEN')
->message('The nightly backup finished')
->title('Backups')
->create();
```
Javascript
A general Javascript library that can be used in any Javascript product.
**Official:**
* **Source**:
* **NPM**:
TypeScript
A general TypeScript library that can be used in any TypeScript application.
**Official:**
* **Source**:
* **NPM**:
Python
A Python library for scripts, servers and Home Assistant integrations. It has a sync client that only uses the standard library, and an async client built on `aiohttp`. Python 3.10 or newer.
**Official:**
* **Source**:
* **PyPI**:
```bash
pip install justpush
```
```python
from justpush import JustPush, Priority
client = JustPush("YOUR_API_TOKEN")
result = client.send(
"The nightly backup finished",
title="Backups",
topic="Servers",
priority=Priority.HIGH,
)
print(result.key) # use it with client.get_message()
print(result.rate_limit.remaining) # messages left this month
```
The SDK checks the message before sending, so an invalid value raises `JustPushValidationError` instead of making a request. `client.verify_token()` checks an API token without sending a message or using quota. For async code, use `AsyncJustPush`, which can share your own `aiohttp.ClientSession`.
Go
A Go library for programs, servers and CLIs. It only uses the standard library and has no dependencies. Go 1.21 or newer.
**Official:**
* **Source**:
* **Go packages**:
```bash
go get github.com/JustPush-io/justpush-go-sdk
```
```go
import "github.com/JustPush-io/justpush-go-sdk"
client, err := justpush.New("YOUR_API_TOKEN")
if err != nil {
log.Fatal(err)
}
result, err := client.Send(ctx, &justpush.Message{
Title: "Backups",
Message: "The nightly backup finished",
Topic: "Servers",
Priority: justpush.PriorityHigh,
})
if err != nil {
log.Fatal(err)
}
fmt.Println(result.Key) // use it with client.GetMessage()
fmt.Println(result.RateLimit.Remaining) // messages left this month
```
Every method takes a `context.Context`, and a `Client` is safe to share between goroutines. Errors work with `errors.Is` and `errors.As`. For example, `client.VerifyToken(ctx)` returns `justpush.ErrUnauthorized` for an invalid token, without sending a message or using quota.
### What the SDKs support
The PHP, Python and Go SDKs cover the full [Messages](/introduction/objects/messages.md) and [Topics](/introduction/objects/topics.md) API:
* Title, message, topic (by name or by topic token), priority and sound
* Up to 10 buttons and up to 4 button groups
* Up to 10 images, from a URL, raw bytes or a file
* Expiry (TTL) and acknowledgements with retries and a callback URL
* Looking up a sent message by its key
* Creating, updating and fetching topics
