Quick start

1. Prerequisites

• A LinkMe workspace with at least one app
• A server/API key from the portal (write scope for link management)
• Node.js 18+

2. Install

npm install @li-nk.me/node-sdk

3. Create and manage links

import LinkMeClient from '@li-nk.me/node-sdk';

const linkme = new LinkMeClient({
  apiKey: process.env.LINKME_SERVER_KEY,
});

// Create a short link
const link = await linkme.createLink({
  appId: 'app_123',
  slug: 'spring',
  deepLink: '/promo/spring',
  redirects: {
    iosStoreUrl: 'https://apps.apple.com/...',
    androidStoreUrl: 'https://play.google.com/...',
    webFallbackUrl: 'https://example.com/spring',
    forceRedirectWeb: false,
  },
});

// List all links for an app
const links = await linkme.listLinks('app_123');

// Update a link
await linkme.updateLink('spring', {
  metadata: { campaign: 'spring-2026' },
});

// Delete a link
await linkme.deleteLink('spring');

CommonJS usage

const LinkMeClient = require('@li-nk.me/node-sdk').default;

Webhook verification

The SDK exports helpers for verifying and parsing webhook payloads:

import {
  parseLinkMeWebhookEnvelope,
  verifyLinkMeWebhookSignature,
} from '@li-nk.me/node-sdk';

const rawBody = req.rawBody.toString('utf8');
const signature = req.get('X-LinkMe-Signature');

if (!verifyLinkMeWebhookSignature(rawBody, signature, process.env.LINKME_WEBHOOK_SIGNING_SECRET!)) {
  res.status(401).send('Invalid signature');
  return;
}

const envelope = parseLinkMeWebhookEnvelope(JSON.parse(rawBody));
// envelope.event — e.g. 'link.click', 'link.claim', 'link.app_open'

Supported webhook events: link.click, link.token_created, link.claim, link.app_open, link.deferred_claim_attempt. Configure webhooks in Developer Settings > Webhooks in the portal.

API reference

| Method | Description | | --- | --- | | createLink(input) | Create a short link. Returns { id, app_id, domain_id, slug, slugUrl } | | getLink(id) | Fetch a link by slug or ID | | listLinks(appId) | List all links for an app | | updateLink(id, updates) | Partial update (snake_case fields, 0 \| 1 flags) | | deleteLink(id) | Permanently delete a link |

createLink options

displayInPortal controls portal visibility:

• false (default in this SDK) — hides the link from the Portal links list (still works as a universal link)
• true — shows it in the Portal

Zod schemas

The SDK exports Zod schemas and inferred types for runtime validation:

• LinkSchema / ExtendedLinkSchema
• CreateLinkInputSchema / CreateLinkResponseSchema
• UpdateLinkInputSchema
• LinkMeWebhookEnvelopeSchema
