We found that our rate limits did not work correctly for few months and allowed more requests than documented. The issue is fixed now and we now return error 429 if our client exceedes allowed request rate

Our API web server used the same technology since 2015 and now it is the time to upgrade it. We've switched to a much faster and newer framework. Also, we added JSON schema validators to our endpoints

Right now size parameter is a size of a single QR code point, so size=300 leads to generation of QR codes 13200x13200px. We'll provide a parameter for total image size soon

Previously, we had a short.cm domain name, few years ago we migrated to short.io domain name. While we plan to support *.short.cm endpoints idefinitely, we recommend changing hostnames to subdomains of short.io

Previously, we supported timezones by providing tzOffset parameter (offset in minutes). This parameter is deprecated now. Please provide tz parameter with timezone name.

We are working on improvements of our speed and fault-tolerance. In order to achieve that we need to make few changes in API. You can safely ignore this message if you use our new link identifiers only (they look like lnk_abc_abc123).

🚧

Breaking change

We are deprecating and removing the "id" parameter in the link creation endpoint. API Clients need to use the "idString" parameter instead. We have already removed the id parameter for new users and those who did not use API before. Starting from Sep 1st, we will remove this parameter for everyone. Using numeric id will work in all existing endpoints for an indefinite time.

You now can add filters to top browsers, versions, countries, and cities.

Bulk clicks endpoint now supports time interval arguments, you can get clicks for any date period (previously it was only total)
