Want to build something custom on top of Hexfit — using an AI tool like Claude, ChatGPT, Lovable, or Bolt to help you do it? There are three different ways to extend Hexfit, depending on what you're trying to build. This article helps you (and your AI assistant) figure out which one fits, then points you to the right guide.
⚠️ These are advanced, developer-oriented features. Some paths need no code at all; others assume a basic technical background.
Which path fits what you're building?
"I want a custom screen or mini-app inside the Hexfit mobile app"
→ Use Custom Tiles. A tile is a small web app that opens inside the Hexfit mobile app for your clients, pre-loaded with their info (name, email, API key) via URL variables.

"I want to connect Hexfit to other tools, without writing code"
→ Use Automations, Hexfit's embedded automation builder (powered by Activepieces). Connect your Hexfit account from Administration → Automations, then build flows using Hexfit's pre-built triggers and actions alongside hundreds of other apps.
(See below for more detail — this is new, so it doesn't have its own article yet.)
"I want to write my own script, tool, or integration against Hexfit's data directly"
→ Use the open API. Generate a key from Administration → Intégrations → Zapier (capped at 500 calls/month), and call Hexfit's endpoints directly.
More on Automations
Administration → Automations lets you connect your Hexfit account and build no-code workflows using Hexfit's own pieces (triggers and actions) — this connection is separate from the API key used for the raw API.
[Placeholder — insert the finalized list of available triggers and actions once ready, e.g.:]
Triggers: (e.g., "New client added", "Session booked")
Actions: (e.g., "Create client", "Update client profile")
Prompting an AI tool to help you build

I want to build something custom on top of Hexfit, a platform used by health
and fitness professionals (kinesiologists, coaches, physiotherapists) to
manage their clients.
Hexfit offers three ways to extend it:
1. Custom tiles — a small web app opened inside the Hexfit mobile app,
pre-loaded with the logged-in user's info via URL variables (apikey,
email, etc.). Guide: https://help.myhexfit.com/en/articles/13921809-custom-tiles-external-developer-guide
2. Automations — a no-code automation builder embedded in Hexfit
(Administration → Automations), using Hexfit's own pre-built triggers
and actions alongside other apps. No API key needed. The user need to use the software to configure it. The technology is base on Activepieces.
3. Open API — direct API access for custom scripts/tools, key generated
from Administration → Intégrations → Api key (500 calls/month cap).
