What is the URL Shortener API?

  2. 2Optionally specify a custom alias, expiration date, or click limit.
  3. 3Resolve via GET /resolve/{code} for analytics and redirect handling.
  4. 4Bulk-shorten up to 100 URLs in one request with /bulk.
  5. 5Per-link click stats: total hits, unique visitors, referrer, country, device.

  "https://url-shortener-by-helix-api.p.rapidapi.com/shorten",

What developers build with this API

Real use cases from production deployments.

1

Marketing Attribution at Scale

Tag every campaign URL with a unique short code. See which channel, ad, influencer, or piece of content actually drives clicks — no UTM headaches, no Google Analytics setup. Data is in your hands.

2

SMS and Twitter Where Length Matters

SMS has a 160-char limit. Twitter/X counts every char. A 200-char URL with tracking parameters becomes a 22-char short link — leaving room for actual copy.

3

Email Newsletters with Real Click Data

Replace raw links with short ones in your Mailchimp/Brevo emails. Get per-link click stats without relying on your ESP's blunt 'clicks' metric — see exactly which CTA worked.

4

Affiliate Link Cloaking

Long Amazon/CJ/Impact affiliate URLs look spammy. Cloak them with branded short codes for a clean look in Instagram bios, YouTube descriptions, and email signatures.

5

QR Code Pairing

Pair every QR you generate with our QR Code API to a shortened tracking URL. You'll know exactly how many people scanned which physical asset.

Frequently asked questions

Real answers to questions developers ask before integrating.

Are links permanent?
Yes, unless you set an explicit expiration date or click limit. Free tier links never expire automatically.
Can I use a custom domain?
Custom domains are supported on Pro+ plans. Point a CNAME to our edge and your short links use yourdomain.com/abc instead of helix.link/abc.
What about NSFW or malicious URLs?
We run every shortened URL through Google Safe Browsing on creation. Malicious URLs are rejected with a 422 response.
How accurate is click tracking?
We log on the edge (Railway) before redirect, so we count every click — including bots if you don't filter. Use the `unique=true` query param on /stats to exclude repeats.
Can I get the original URL back from a short code?
Yes — GET /resolve/{code} returns the full original URL plus stats. Useful for preview pages and tooltips.
How do I handle 404s on deleted links?
Configure a fallback URL in your account settings — expired/deleted links redirect there instead of returning 404.
