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).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.
- Android (Gradle)
- Web (npm)
- .NET (NuGet)
- Swift (macOS)
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.
Validate an identity
