# Important notes

## Important notes
- **Initialize early.** The SDK needs time to collect device signals before it can produce a token. Initialize as early in your app lifecycle as you can.
- **Fresh tokens per call.** Generate a new `diSessionToken` for each API call — don't reuse them across requests.
- **Both endpoints.** Pass `diSessionToken` to **both** the Prefill and Onboarding requests for full SNA coverage.
- **Graceful fallback.** If SDK init or token generation fails, just proceed without the token. The user falls back to OTP verification — your flow still completes.
