Galva Admin Node SDK

Node.js SDK for syncing billing events and managing end users with Galva.

Installation

npm install galva-admin-node

Peer dependencies (install as needed):

npm install @paddle/paddle-node-sdk  # For Paddle
npm install googleapis               # For Play Store

Quick Start

import { Galva } from 'galva-admin-node';

const galva = new Galva({ apiKey: 'your-api-key' });
// Or set GALVA_API_KEY environment variable

Billing Events

With Pre-verified Payloads

Use when you've already decoded/verified payloads yourself.

// App Store
await galva.billingEvent.appstore('user-123', {
  signedPayload: '...',
  bundleId: 'com.example.app',
  appAppleId: 123456789,
});

// Play Store (decoded notification)
await galva.billingEvent.playstore('user-123', decodedNotification);

// Paddle (verified event)
await galva.billingEvent.paddle('user-123', verifiedEvent);

With Credentials (Auto-verification)

Use withCredentials() to let the SDK handle decoding and verification.

const galvaWithCreds = galva.withCredentials({
  appstore: {
    bundleId: 'com.example.app',
    appAppleId: 123456789,
  },
  playstore: {
    email: '[email protected]',
    key: '-----BEGIN PRIVATE KEY-----\n...',
  },
  paddle: {
    apiKey: 'pdl_...',
    secretKey: 'whsec_...',
  },
});

// App Store (signed payload only)
await galvaWithCreds.billingEvent.appstore('user-123', signedPayload);

// Play Store (base64 from Pub/Sub - auto-decodes and fetches subscription)
await galvaWithCreds.billingEvent.playstore('user-123', base64Payload);

// Paddle (raw body + signature - auto-verifies)
await galvaWithCreds.billingEvent.paddle('user-123', rawBody, signature);

End User Management

import { EndUserDefaultTraitName } from 'galva-admin-node';

// Identify with traits
await galva.endUser.identify('user-123', {
  traits: {
    [EndUserDefaultTraitName.EMAIL]: '[email protected]',
    [EndUserDefaultTraitName.FULL_NAME]: 'John Doe',
    customTrait: 'value',
  },
});

// Update default profile info
await galva.endUser.updateDefaultInfo('user-123', {
  email: '[email protected]',
  fullName: 'John Doe',
  country: 'US',
});

Configuration

interface GalvaOptions {
  apiKey?: string;                          // Falls back to GALVA_API_KEY env
  environment?: 'production' | 'development'; // Falls back to NODE_ENV
  timeout?: number;                         // Request timeout in ms (default: 10000)
}

Error Handling

import { GalvaError } from 'galva-admin-node';

try {
  await galva.billingEvent.appstore('user-123', payload);
} catch (error) {
  if (error instanceof GalvaError) {
    console.error(error.code, error.message);
  }
}
