This walkthrough takes you from nothing to a working verification. Each step links to the full reference.
1

Onboard and create an API key

Sign in to the Client Portal, create an API key, and note the key ID and key secret. The secret is shown once — store it in your backend’s secret manager. Scope the key to the verification methods your app uses (e.g. eid_manual, eid_card_read_finger).
2

Get the SDK from Nexus

Configure your package manager for the MBKYC Nexus repositories and add the dependency for your platform. See Get the SDK and the package matrix.
3

Implement a token signer

The SDK never holds your API secret. When it needs to authenticate, it hands you some bytes to sign; you forward them to your backend, which holds the secret and signs them. See Authentication.
4

Initialize and register the device

5

Validate an identity

Add a fingerprint to also run biometric matching — see Biometrics.
