ON!Track Unite

Unite Benefits

ON!Track Unite increases customers’ productivity by breaking down data silos and enables integration partnerships. The ON!Track Unite API allows a seamless data flow between the jobsite, the warehouse, the office, and all the other applications that customers use. It is an ever-expanding offering of modern and easy-to-use products and services for API-based software integration. It is built with the productivity and automation needs of ON!Track customers in mind, as well as the pain points of the developers in customer and partner organizations.

Being an add-on to ON!Track that expands its core functionalities with software integration capabilities, the goal of ON!Track Unite is to help ON!Track users to boost their productivity and reduce the complexity of working with increasingly many applications. This goal can be achieved by building expansions on top of existing ON!Track functionalities and/or automating the business processes involving ON!Track and other applications.

Integration scenarios

ON!Track Unite is designed to support two main scenarios based on the purpose of the integration and the software to be integrated with ON!Track. In both cases, the integrations are based upon the API published on this hub.


Customers build integrations in-house by leveraging the ON!Track Unite API (or source a 3rd party vendor to do so). The integration is tailored to the specific customers’ needs and the applications they use. Build-your-own integrations are meant to be used internally by the customer organizations that develop them and are typically not sold to other parties.


Software companies leverage the available ON!Track Unite API to build an integration between ON!Track and the application they develop (or distribute) to create a seamless experience for the shared users. Such integrations are typically standardized, and limited in terms of customization possibilities.

The customer base of these companies typically overlaps to some extent with that of ON!Track, and offering the two applications pre-integrated have many benefits for the customers and the two companies. In this case, the integration is offered as a “plug-and-play” solution and it is meant to be made available or sold to multiple customers. The available integrations are listed in the Built-for-you marketplace section.

Hilti ON!Track

Since 1941, at Hilti we have been creating products, services, and software to help our customers build faster, safer, greener, and with more daring. With that legacy in mind, we have created the construction asset management solution ON!Track that delivers transparency on tools and equipment (regardless of manufacturer).

Hilti ON!Track is a leading global solution specifically designed for construction companies and professionals for managing and tracking equipment, consumables, and other assets. While helping to reduce operational and overhead costs, using Hilti ON!Track brings more clarity and efficiency to any construction business. 

ON!Track is a complete tool tracking and asset management solution made up by a three-part system: it combines a cloud-based software (desktop and mobile app) with the use of rugged hardware (tags, gateways, etc.) and of dedicated service, support, and implementation team. 

OT3 Triangle

Available globally, this professional solution helps manage all construction assets and equipment, regardless of the manufacturer. The software makes it easy to track and search for assets to minimize losses, to maintain inventory lists quickly and easily, and to get automated alerts as reminders for repairs, servicing, and inspections. It also has a powerful module to manage consumables and commodities with functionalities ranging from stock level monitoring to replenishment proposals.

OnTrack Overview

ON!Track is a cloud-based application that is available not only in a desktop version but also as a mobile app both for Android and iOS devices.

Integration use cases

We are continuously expanding our offering by adding new API endpoints and improving existing ones. The description you find below is for the two most common integration use cases currently offered, the syncing of master data and the exporting of transfer data. The following picture gives a representation of the high-level integration data flows currently supported.


Less manual effort to update applications

Thanks to the read and write of the master data from/to external systems, the data of assets, location, and workers can be automatically and effortlessly synced among different apps. Master data for assets, locations, and employees are synced between ON!Track and another application, this applies to both the initial item creation and the following edits. With this use case you no longer need to copy/paste large amounts of static data, and everything is always updated.

More accurate job costing through ERP integration

With the possibility to read the asset transfer data, the timestamps of when assets change their current location as well as the details of the locations are exported via API. They can then be used in other software (typically construction ERP systems) to calculate the time an asset is on a given jobsite and, for example, correctly allocate asset costs, create accurate invoices, or simply track time at a given location.

Discover more use cases Available API endpoints support many more workflows that you can freely implement in the integration. Refer to the API documentation to discover more on what's possible with the currently available endpoints.

What’s new

In the most recent releases, we added these APIs and functionalities:

  • Asset geolocation: it is now possible to get the “last-seen-at” location of assets, in the form of GPS coordinates or confirmed location by a gateway, so you can automate the allocation of assets in given jobsites or warehouses
  • Asset service: users can now retrieve via API all the open services assigned to an asset
  • Asset costing: all asset’s API endpoints now feature the asset cost type and value
  • Quantity items catalog and allocations sync: Sync with ON!Track the catalog of the quantity items (consumables and commodities) that your company uses and allocate them in different places in ON!Track via API
  • Quantity items stock management: there is a set of API endpoints to change the stock levels of quantity items, mark them as consumed, as well as read the stock level history. This will be particularly helpful for accounting and invoicing and to improve warehouse management
  • Transfer filters: it is now possible to filter the list of transfers and get a subset of the whole transfer list based on the transfer dates

What’s coming

We are constantly working on expanding the offering of ON!Track Unite API endpoints. The ones that we are working on and will be released soon are:

  • Asset IoT data with Nuron: Nuron is an all-new cordless platform that radically simplifies work on construction sites, enhances tool park management, drives performance to much higher levels and improves operator health protection. Nuron is based on a single battery system that covers all relevant applications from light- to heavy-duty. Utilization, idle time, and other IoT asset data are collected via the battery and automatically uploaded to the Hilti cloud. From there, data and the relative insights are shown in ON!Track and will also be openly available with dedicated APIs!
  • Transfer import: we will offer the possibility to perform transfers in ON!Track when triggered from an external system; therefore, the asset’s current location will be updated accordingly
  • Asset service/maintenance: we will introduce a series of new endpoints for syncing the asset’s service or maintenance dates and details
  • Documentation and attachments: export and import via API of attachments, pictures, and documentation
  • General improvements: various enhancements to the currently available API to improve their usability and scope

Please get in touch with us if you have some feedback or suggestions on this roadmap and in case of need of additional endpoints.
