1. Set Return URL Option in Dashboard

You can set the Return URL option in the Dashboard. When the KYC process is completed and the submitter selects the “Ok” button or waits for 5 seconds, the page redirects to the Return URL address with the dynamic field parameters. Starting with the 2026-04 update, users can also return to the configured Return URL when they land on an error page, and in that case the errorCode parameter is included so that your service can identify the reason for the block.

2. Support to parameters in Dynamic Fields

​

​

​

​

​
kycStatus
string
KYC result. Following this parameter name is camelCase (case-sensitive). Based on the result, it returns approved, pending, or rejected.
​
errorCode
string
(2026-04 New) The error code passed when the user is taken to an error page. Examples: DE-20000 (Device Verification failure), DE-30000 (Fingerprint detection), DE-40000 (Device duplicate exceeded), TK-10001 (token expired). Not passed on normal completion. See Error Codes and Pages for the full code list.

​
2-2. Returning to Return URL from an error page

When a user is blocked by pre-verification (Device Info, VPN/Proxy, etc.) or token validation and is taken to an error page, they can return to your service via the Return URL button — as long as Error Code (errorCode) is checked in dynamic fields in the Dashboard. An example of the URL passed in this case is: 
https://yourapp.com/verification-complete?kycStatus=rejected&errorCode=DE-20000
Branching logic based on errorCodeYour service can use the errorCode value to provide users with appropriate follow-up guidance (e.g., recommending use of a mobile device, directing them to request a new token, etc.).

​
2-3. Encrypted option applied

Encryption is enabled when the “encrypted” parameter is included in the final return URL. AES-256-ECB is required to decrypt the value. Please consult this guide section for further information. By using this guide, you can effectively return URL with Query String in ID check to optimize your KYC process and enhance user experience.
