Build on FUSE
Everything you set up in the FUSE brand portal (programs, products, pricing, coupons, checkout and your storefront) you can also reach from your own code, or from an AI assistant. Pick the one that fits how you work.
FUSE API
A JSON API for your brand, authenticated with an API key. Use it to connect your own website, app or back office to FUSE.
- Programs, products, pricing and coupons
- Checkout links for your own site
- Webhooks when things change
- A full interactive reference
AI Connector
Connect Claude or ChatGPT to your FUSE brand and set up or run it by chatting. No code, no API key: you sign in with your brand portal login.
- Build programs and check they're ready to go live
- Change prices, coupons and your storefront
- Ask how the business is doing
- Asks you before anything public or costly
Which one do I need?
If you are writing software (a custom storefront, a sync with another system, a script), use the API. If you want to manage your brand in plain English from an AI app, use the AI connector. They work on the same brand account and you can use both.
Getting access
Have a FUSE brand account
Both run against your brand. If you don't have one yet, see plans and pricing.
API: create a key
In the brand portal, open Settings → Organization → API Keys and create a key. It's shown once, so copy it straight away.
AI: add the connector
In Claude or ChatGPT, add a custom connector pointing at https://mcp.fusehealth.com/mcp and sign in with FUSE.
