Onboarding Flow​

Nium offers only Manual KYB flows for customers in Hong Kong. Submission of business documents may be required depending on the business type. Check HK Required Documents.

Step 1: Upload required documents​

Use the Files API request to upload required business documents.

The response returns a fileId.

You must reference this fileId when submitting the onboarding request.

For the full list of required documents, see HK Required Documents.

Step 2: Applicant declaration​

The authorized representative must confirm the following statement:

I certify that I am the authorized representative of the customer; all information provided and documents submitted are complete and correct. I confirm that I have provided all the UBOs present. I have read and accepted the Nium Terms and Conditions.

Capture this confirmation using a clickwrap and submit the following fields in your onboarding request:

Step 4: Complete Identity Verification (KYC)​

The applicant opens the Nium’s Pre-built KYC form.

Access is protected by a One-Time Password (OTP) sent to the registered email address of the applicant.

HK onboarding supports both electronic and manual identity verification for applicant or stakeholders.

Electronic KYC​

Complete verification using live selfie with documents like passport or national id. If unsuccessful, document upload is required.

Manual KYC​

If Electronic verification fails customer can choose to complete the verification manually.

Document requirements: Passport or National ID

See HK Required Documents for more information on POI/ POA documents for identity verification

Step 5: Compliance review​

After KYC is completed for the applicant

Nium’s compliance team reviews submitted information offline.

If additional details are required:

  • An RFI (Request for Information) is raised
  • The customer responds through the RFI Hosted Form

Nium returns the final outcome via webhook.

For next steps based on application status, see Customer Onboarding Lifecycle.

Multi-layer ownership​

If another corporate entity owns more than 25% (directly or indirectly):

  • Declare all corporate stakeholders in the ownership chain.
  • Submit ownership structure documentation.

See HK Required Documents for more information.

Position mapping​

A Yes value indicates that the position can be submitted for that businessType.
A blank cell means the position is not applicable.

You can also retrieve valid positions dynamically using Fetch Corporate Constants with category = position.
