# VerifyYou

## Docs

- [Test Key](https://docs.verifyyou.com/api-reference/api-keys/test-key.md)
- [Confirm a verification token](https://docs.verifyyou.com/api-reference/confirmations/confirm-a-verification-token.md): Exchange the `vyt` token the user returned with for the authoritative verification result. **Secret key only** — call this from your backend before granting access.
- [Lock a confirmation](https://docs.verifyyou.com/api-reference/confirmations/lock-a-confirmation.md): Mark a confirmation as used so the same `vyt` token can't be confirmed again — single-use enforcement. **Secret key only.** After locking, `GET /v3/confirmations/{token}` returns `verified: false`.
- [Initialize a verification session](https://docs.verifyyou.com/api-reference/verification-flow/initialize-a-verification-session.md): Initialize a session before the user verifies and get back a hosted verification link with a queued-up session. Redirect the user to the returned `url`; they come back to your `return_path` with `?vyt=<token>&vyc=<0|1>`, which you confirm server-side at `GET /v3/confirmations/{token}`.
