Connect TopstepX in 3 steps
- In TopstepX: Settings → API, and subscribe to ProjectX API access (a paid add-on billed by ProjectX).
- Copy the API key and your TopstepX username.
- Paste both into Afterfill → Connections → TopstepX. Afterfill checks the login and lists your accounts.
- ProjectX keys cannot be limited to read-only, so Afterfill only ever calls read endpoints.
- Disconnect any time; the stored key is deleted immediately.
