Authentication

Exchange your NSL client credentials for a short-lived OAuth token. Reuse it for every subsequent request until it expires.

How It Works

1. Call POST /oauth/token with your NSL client id + secret.
2. Cache the token for 60 minutes; refresh proactively at ~55 minutes.
3. Send Authorization: Bearer <token> on every downstream request.

tip

Tokens last 60 minutes. Prepare to refresh before they expire to avoid 401s.

Token Request Payload

{
  "client_id": "<your NSL client id>",
  "client_secret": "<your NSL client secret>",
  "audience": "https://api.nearspacelabs.com",
  "grant_type": "client_credentials"
}

Code Examples

Python

import requests

NSL_ID = "YOUR NSL ID"
NSL_SECRET = "YOUR NSL SECRET"

def get_auth_token():
    auth_headers = {'content-type': 'application/json'}
    post_body = {
        'client_id': NSL_ID,
        'client_secret': NSL_SECRET,
        'audience': 'https://api.nearspacelabs.com',
        'grant_type': 'client_credentials'
    }
    req = requests.post(
        'https://api.nearspacelabs.net/oauth/token',
        json=post_body,
        headers=auth_headers
    )
    req.raise_for_status()
    return req.json()['access_token']

auth_token = get_auth_token()
print(f"Token acquired: {auth_token[:20]}...")

JavaScript

const fetch = require('node-fetch');

const NSL_ID = "YOUR NSL ID";
const NSL_SECRET = "YOUR NSL SECRET";

async function getAuthToken() {
  const authHeaders = { 'Content-Type': 'application/json' };
  const postBody = {
    client_id: NSL_ID,
    client_secret: NSL_SECRET,
    audience: 'https://api.nearspacelabs.com',
    grant_type: 'client_credentials'
  };

  const response = await fetch('https://api.nearspacelabs.net/oauth/token', {
    method: 'POST',
    headers: authHeaders,
    body: JSON.stringify(postBody)
  });

  if (!response.ok) {
    throw new Error(`HTTP error! Status: ${response.status}`);
  }

  const data = await response.json();
  return data.access_token;
}

getAuthToken().then(token => console.log(`Token: ${token.slice(0, 20)}...`));

Bash

TOKEN=$(curl -s -X POST https://api.nearspacelabs.net/oauth/token \
  -H "Content-Type: application/json" \
  -d '{
    "client_id": "YOUR NSL ID",
    "client_secret": "YOUR NSL SECRET",
    "audience": "https://api.nearspacelabs.com",
    "grant_type": "client_credentials"
  }' | jq -r '.access_token')

echo "Token: ${TOKEN:0:20}..."
