Quick Start

Up and running in 3 steps

From zero to your first API response in under 5 minutes.

1

Generate an API key

Go to your Apex POS panel → REST API → Generate API Key. Copy the key — it won't be shown again.

2

Make your first request

Send a GET request to the health endpoint to verify your connection. 

curl -H "X-API-Key: apx_your_key" \
  https://api.apex-pos.com/rest_api/v1/health
const res = await fetch('https://api.apex-pos.com/rest_api/v1/health', {
  headers: { 'X-API-Key': 'apx_your_key' }
});
const data = await res.json();
console.log(data);
import requests

res = requests.get(
    'https://api.apex-pos.com/rest_api/v1/health',
    headers={'X-API-Key': 'apx_your_key'}
)
print(res.json())
