Authentication

To use our APIs, you need to authenticate your requests. At Natech, we support two methods of authentication:

API Key Authentication

Include your API key in the header of each request:

Authorization: Bearer YOUR_API_KEY

OAuth 2.0

For more secure applications, we recommend using OAuth 2.0[https://oauth.net/2/]. Here's how to get an access token:

1. Redirect the user to our authorization URL
2. Receive the authorization code
3. Exchange the code for an access token

cURL

curl -X POST https://api.example.com/oauth/token \\
  -d "grant_type=authorization_code" \\
  -d "client_id=YOUR_CLIENT_ID" \\
  -d "client_secret=YOUR_CLIENT_SECRET" \\
  -d "code=AUTHORIZATION_CODE"

Python

import requests

data = {
    'grant_type': 'authorization_code',
    'client_id': 'YOUR_CLIENT_ID',
    'client_secret': 'YOUR_CLIENT_SECRET',
    'code': 'AUTHORIZATION_CODE'
}

response = requests.post('https://api.example.com/oauth/token', data=data)
access_token = response.json()['access_token']

JavaScript

const data = new URLSearchParams();
data.append('grant_type', 'authorization_code');
data.append('client_id', 'YOUR_CLIENT_ID');
data.append('client_secret', 'YOUR_CLIENT_SECRET');
data.append('code', 'AUTHORIZATION_CODE');

fetch('https://api.example.com/oauth/token', {
  method: 'POST',
  body: data
})
.then(response => response.json())
.then(data => {
  const accessToken = data.access_token;
});
