Links

Short links are the backbone of Postli’s tracking. Every link you create gets a unique short URL on the pstl.sh domain. When someone clicks it, Postli records the click, enriches it with geo and device data, and sets a first-party cookie for revenue attribution.

Links list

The /links page shows all your short links in a searchable, paginated table. Each row displays the title, short URL, click count, status (Active / Inactive), and creation date.

Actions from the list:

Create a link

Click Create link to open the link builder. The form has four sections:

Link details

UTM parameters

Add utm_source, utm_medium, utm_campaign, utm_term, and utm_content to the link. These are appended to the destination URL at redirect time so your analytics platform (Google Analytics, Triple Whale, etc.) sees them.

UTM Templates — if you reuse the same UTM set across multiple links, save it as a template. Templates appear in a dropdown for quick application.

Targeting & access

Advanced

Social preview (right sidebar)

Set custom og:title, og:description, and og:image so the short URL shows a rich preview when shared on social platforms. Use Pick from media to choose from your media library or Shopify files.

QR code preview

Click Generate preview to see a QR code for the destination URL. The QR is generated server-side and can be downloaded as a PNG from the link detail page.

Link detail

Clicking a link title opens its detail page, which shows:

Actions: Edit (opens a modal with all editable fields), Copy short URL, Delete.

Short-link domain. All short URLs are served from pstl.sh. Redirects are rate-limited and cached in Redis for sub-50ms response times. Click events are processed asynchronously — the redirect fires immediately while geo/device enrichment happens in the background.
