FAQ

When I need to be ready with my integration?

Smart-ID RP API v1/v2 will remain working as is. Still we encourage you to start your developments to implement new end-user friendly and more secure usage flows.

Do new flows work with all Smart-ID app versions?

No. For end-user to be able to use new flows app must be updated to at least version 29. User may see the following error messages when using old Smart-ID app with new flows:

Same-device flows - fallback page

Cross-device flow - Invalid QR code
