Integration with Trinsic

Indonesia NIK verification is integrated into Trinsic's identity acceptance network allowing businesses to verify users against the government system of record in Indonesia.

Permission required: Yes, this method requires registration before you can activate it for your users. Please contact Trinsic to begin this process.

User Flow

Indonesia NIK requires the user to input some data about themselves into a form. A match against the system of record is then completed against the data. To see a demo of this flow, watch this video.

Customers can bypass the form-fill step by passing in known identity data about the user when launching the integration.
