WARNING! If your school district/organization is using our XML API, you’ll need to switch to our JSON API as soon as possible. We will be sunsetting the XML API in March of 2026. You can go to Getting K-12 Data Using the JSON API for details about our JSON API offering. If you have any questions about migrating from XML to JSON, you can email k12apisupport@calamp.com.


CalAmp K-12 Mobile App


  • Updated the backend processing to ensure that data for the last peripheral report and last route sync is being stored in the CalAmp K-12 database.


Here Comes the Bus


  • On the HCTB Visibility tab of the HCTB Settings screen, added a new toggle, Display Bus Only Inside Home Stop Radius on the HCTB Map, which, when enabled, will limit parents’ ability to see their students’ bus on the map to only their home bus stop radius.

    When users toggle this on, a Visibility Radius field will appear, in which they can enter the radius length that the bus will be viewable (in feet or meters – with a range of 320 to 16,400 feet or 98 to 4,999 meters).

    Note: This feature will work only with HCTB app version 3.6.5 and higher.
  • Fixed a bug that wasn’t storing the usernames and the date and time when users made changes to the HCTB Visibility tab.


JSON API


  • In CalAmp K-12, on the Groups screen, added validation that will prevent JSON API users from being assigned to the All Vehicles group.
