Update user

PUT https://api.balampay.com/sandbox/v1/users/{userId}

Update an existing user's information. All fields are optional — only the fields you include will be updated.

Automatic Re-verification: If a sensitive field changes (e.g., name, birth_date, address, SSN, document info), automatic KYC/KYB re-verification is triggered in the background. The response includes requires_reverification to indicate this.

Response includes:

• updated_fields — List of fields that were actually changed
• requires_reverification — Whether KYC/KYB re-verification was triggered
• eligible_products — Updated product eligibility after the change
• missing_fields — KYC/KYB fields still required (if any)
• warnings — Non-fatal issues (e.g., document upload failures)

Authentication: Both x-api-key header and Authorization: Bearer <token> header are required.
