Frequently Asked Questions
Everything you need to know about ExaLink.
What is ExaLink?
ExaLink is Sendexa’s smart link platform (Beta) for short URLs on sndx.in, branded domains, QR codes, bio pages, smart routing, and full click analytics—built for SMS, WhatsApp, email, ads, and offline campaigns.
What domain do short links use?
By default, public short links resolve on https://sndx.in/{slug}. You can also attach a verified custom domain (e.g. go.yourbrand.com) and set it as the default host.
Can I use my own domain?
Yes. Add a hostname in the dashboard, complete DNS verification (TXT challenge at _exalink-challenge.<domain>), then create links on that domain.
What analytics do I get?
Per link you get total clicks, unique visitors, country breakdown, device mix (mobile, desktop, tablet, bot), referrers, and timeseries. Business overview, recent clicks, and conversion reports are available in the dashboard and API.
How does smart routing work?
Attach routing rules by device or country. The first matching rule wins; otherwise traffic falls back to the default destination—ideal for app-store links and regional landing pages.
What access controls are available?
Password-protect a link, set an expiresAt timestamp, and optionally cap traffic with maxClicks. Inactive or expired links stop redirecting immediately.
Do QR codes and bio pages share analytics?
QR codes encode your ExaLink short URL, so scans flow through the same redirect and analytics pipeline. Bio pages live at sndx.in/m/{handle} with their own view counts and linked destinations.
Are webhooks available?
Yes. Subscribe to exalink.click (successful redirect) and exalink.converted (attributed signup, purchase, lead, or custom event) with HMAC-signed payloads.
How do I create links via API?
POST to https://api.sendexa.co/v1/exalink/links with Basic auth (dashboard Base64 token). Pass destination, optional slug, domain, title, utm, password, maxClicks, and expiresAt.
