CSV timestamps use a 256 Hz tick base; see the timestamp conversion note in the same category. **API access.** The REST API returns all channels and metrics with an authenticated token. Academic users can request API access for a university project through support with the account email and project description. The Demo SDK is available on request; licensed SDK and API use for products and platforms is quoted by the sales team. **What to include in your request.** Account email, whether you need retrospective exports or continuous access, and the target format. This shortens the exchange to a single reply. - [Hexoskin OneSync Software](https://support.hexoskin.com/hexoskin-onesync-software?hsLang=en#main-content) - [Hexoskin OneSync Advanced Features](https://support.hexoskin.com/hexoskin-onesync-software?hsLang=en#hexoskin-onesync-advanced-features) - [Hexoskin OneSync Basics](https://support.hexoskin.com/hexoskin-onesync-software?hsLang=en#hexoskin-onesync-basics) - [Hexoskin Data Analysis](https://support.hexoskin.com/hexoskin-data-analysis?hsLang=en) - [Hexoskin Support Topics](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#main-content) - [Hexoskin Mobile App](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-mobile-app) - [Hexoskin Articles](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-articles) - [Hexoskin Set-up and Configuration](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-set-up-and-configuration) - [Hexoskin Recorder](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-recorder) - [Hexoskin Troubleshooting](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-troubleshooting) - [Hexoskin FAQ](https://support.hexoskin.com/hexoskin-faq?hsLang=en#main-content) - [Frequently Asked Question for the Hexoskin community](https://support.hexoskin.com/hexoskin-faq?hsLang=en#frequently-asked-question-for-the-hexoskin-community) - [Order](https://support.hexoskin.com/hexoskin-faq?hsLang=en#order) - [Hexoskin OneView dashboard](https://support.hexoskin.com/hexoskin-oneview-dashboard?hsLang=en) - [Hexoskin OneSync](https://support.hexoskin.com/hexoskin-onesync?hsLang=en) - [Hexoskin Smart Garments](https://support.hexoskin.com/hexoskin-smart-garments?hsLang=en#main-content) - [Hexoskin Device](https://support.hexoskin.com/hexoskin-smart-garments?hsLang=en#hexoskin-device) - [Hexoskin App](https://support.hexoskin.com/hexoskin-app?hsLang=en) - [Hexoskin Dashboard](https://support.hexoskin.com/hexoskin-dashboard?hsLang=en) - [Help for Developers](https://support.hexoskin.com/help-for-developers?hsLang=en) - [Ordering Your Hexoskin](https://support.hexoskin.com/ordering-your-hexoskin?hsLang=en) - [Hexoskin Support](https://support.hexoskin.com/hexoskin-support?hsLang=en) [![Hexoskin - Logo - No Tagline - Rectangle - White - Transparent-Nov-28-2023-04-38-48-1716-PM](https://support.hexoskin.com/hs-fs/hubfs/Hexoskin%20-%20Logo%20-%20No%20Tagline%20-%20Rectangle%20-%20White%20-%20Transparent-Nov-28-2023-04-38-48-1716-PM.png?width=200&height=50&name=Hexoskin%20-%20Logo%20-%20No%20Tagline%20-%20Rectangle%20-%20White%20-%20Transparent-Nov-28-2023-04-38-48-1716-PM.png "Hexoskin - Logo - No Tagline - Rectangle - White - Transparent-Nov-28-2023-04-38-48-1716-PM")](https://hexoskin.com) 5800, Saint-Denis, Suite 601, Montréal (Québec), Canada Copyright © 2026, Hexoskin
