Webhooks

Real-Time Webhooks

Trigger downstream actions. Receive instant HTTP POST notifications when visitors click links, triggers fire, or custom conversion pixels validate.

Event Types

Lynki fires JSON payloads to your configured HTTP endpoint when events trigger inside your workspace.

link.click • Fired instantly on redirect

Triggered whenever a visitor hits a Lynki short link (includes country, browser, referrer, and unique click diagnostics).

conversion.track • Fired on landing page event validation

Triggered when a visitor completes a conversion action (such as registration, opt-in, or cart checkouts).

Verifying Signatures

Protect your endpoint from spoofing. Lynki attaches a signature header key `X-Lynki-Signature` to verify that payloads originate from our edge servers.

The signature is an HMAC-SHA256 signature calculated from the raw payload body using your workspace's unique webhook secret signing key.
