Quick Start

Integrate with the FluxiQ NPC API in 5 minutes.

1. Get your API Key

To access the API, you need an API Key. Contact support to obtain your credentials:

• Email: suporte@fluxiq.com.br
• Portal: npcadmin-dev.fluxiq.com.br

2. Environments

Environment	Base URL	Description
Local	http://localhost:4000/api/v1/central	Local development
Sandbox	https://sandbox.pixconnect.com.br/api/v1/central	Testing and staging
Production	https://api.pixconnect.com.br/api/v1/central	Production environment

3. First Request

Let's verify that your API Key is working correctly by making a request to the health check endpoint.

cURL

curl -X GET "https://sandbox.pixconnect.com.br/api/v1/central/health" \
  -H "X-API-Key: your_api_key_here" \
  -H "Content-Type: application/json"

JavaScript

const response = await fetch(
  "https://sandbox.pixconnect.com.br/api/v1/central/health",
  {
    method: "GET",
    headers: {
      "X-API-Key": "your_api_key_here",
      "Content-Type": "application/json",
    },
  }
);

const data = await response.json();
console.log(data);

Python

import requests

url = "https://sandbox.pixconnect.com.br/api/v1/central/health"
headers = {
    "X-API-Key": "your_api_key_here",
    "Content-Type": "application/json"
}

response = requests.get(url, headers=headers)
print(response.json())

4. Expected Response

If everything is configured correctly, you will receive the following response:

{
  "status": "ok",
  "timestamp": "2026-02-03T12:00:00Z",
