# Quickstart
> Send your first event with Flux in under 5 minutes
## Prerequisites
Before you begin, you'll need:
* A [Flux account](https://app.flux.dev/signup)
* Your API key from the [dashboard](https://app.flux.dev/settings/api-keys)
* Node.js 18+ (or Python 3.8+, Go 1.19+)
## 1. Install the SDK
```bash npm theme={null}
npm install @flux/node
```
```bash yarn theme={null}
yarn add @flux/node
```
```bash pnpm theme={null}
pnpm add @flux/node
```
```bash pip theme={null}
pip install flux-python
```
```bash go theme={null}
go get github.com/flux-events/flux-go
```
## 2. Initialize the Client
Create a new Flux client with your API key:
```typescript theme={null}
import Flux from '@flux/node';
const flux = new Flux(process.env.FLUX_API_KEY);
```
Never hardcode your API key. Use environment variables to keep it secure.
## 3. Send an Event
Events in Flux have a `type` and a `data` payload. The type is a string that identifies the kind of event (we recommend using dot notation like `user.signup`).
```typescript theme={null}
const event = await flux.events.send({
type: 'order.completed',
data: {
orderId: 'ord_8x7kj2',
amount: 9900,
currency: 'usd',
customerId: 'cus_abc123'
}
});
console.log('Event sent:', event.id);
```
## 4. Verify It Worked
Head to the [Events tab](https://app.flux.dev/events) in your dashboard. You should see your event logged with its full payload and metadata.
