PowerLab REST API Reference

Authentication

Every request requires a Bearer token. Generate a key from Settings → API Keys. Keys look like plk_… and are shown exactly once at creation.

curl -H "Authorization: Bearer plk_your_key_here" \ https://powerlab.marinepowerlab.com/api/v1/projects

Invalid or revoked keys return 401 Unauthorized. A valid key whose user isn't on an active Pro plan returns 403 Forbidden.

Code samples

Replace plk_… with your real key. The same pattern works for every endpoint below.

cURLbash

curl -H "Authorization: Bearer plk_your_key_here" \
  https://powerlab.marinepowerlab.com/api/v1/projects

Python (requests)python

import os, requests

key = os.environ['POWERLAB_API_KEY']
res = requests.get(
    'https://powerlab.marinepowerlab.com/api/v1/projects',
    headers={'Authorization': f'Bearer {key}'},
    timeout=15,
)
res.raise_for_status()
for p in res.json()['data']:
    print(p['name'], '—', p['system_voltage'], 'V')

JavaScript (Node / fetch)javascript

const key = process.env.POWERLAB_API_KEY;
const res = await fetch('https://powerlab.marinepowerlab.com/api/v1/projects', {
  headers: { Authorization: `Bearer ${key}` },
});
if (!res.ok) throw new Error(`${res.status} ${await res.text()}`);
const { data } = await res.json();
for (const project of data) {
  console.log(project.name, '—', project.system_voltage, 'V');
}

Google Sheets (Apps Script)javascript

function importPowerLabProjects() {
  const key = PropertiesService.getScriptProperties().getProperty('POWERLAB_API_KEY');
  const res = UrlFetchApp.fetch(
    'https://powerlab.marinepowerlab.com/api/v1/projects',
    { headers: { Authorization: 'Bearer ' + key } }
  );
  const { data } = JSON.parse(res.getContentText());
  const rows = data.map(p => [p.name, p.vessel_type, p.system_voltage, p.updated_at]);
  const sheet = SpreadsheetApp.getActiveSheet();
  sheet.getRange(1, 1, rows.length, rows[0].length).setValues(rows);
}

Common integrations

Google Sheets

Apps Script snippet above. Schedule it on a time-driven trigger to keep your spreadsheet in sync nightly.

Zapier / Make

Use their generic "Webhooks by Zapier" / "HTTP" module with GET + Bearer auth. No dedicated connector yet.

Python / Pandas

pd.read_json on the JSON response or CSV loads endpoint. Good for BoM analysis across multiple projects.

Postman / Bruno

Set collection-level Authorization to Bearer. Import the full base URL and hit each endpoint interactively.
