license Token
EidKit license token. Reserved for future licensing enforcement — currently unused.
When EidKit introduces runtime licensing, this field will accept either:
A JWT token (offline license — no network required, expiry enforced locally)
An API key (online license — validated against the EidKit licensing endpoint)
Setting this field now is forward-compatible — your integration will not need to change when licensing is activated. If null, the SDK operates in development mode with no enforcement — suitable for building and testing your integration before going to production.
