Update customer information
Update customer information like phone number, email, etc.
Additional Parameters
shareToken (optional)
Type: string
Description: A SumSub share token that allows importing existing KYC verification data for crypto rails customer management.
When you update a customer with a shareToken from SumSub, their KYC data will be automatically fetched and imported for crypto rails operations. This PATCH method is specifically designed for the crypto rails workflow where:
- Customers are created first: Create customer with minimal data
{} - ShareTokens are added via PATCH: Each time a new token is generated at SumSub
- Short TTL management: Tokens expire quickly, requiring repeated PATCH updates
- Crypto rails requirement: KYC verification is mandatory for crypto transfers
This approach significantly improves the user experience by:
- Eliminating redundant verification: Customers don't need to re-verify their identity
- Faster crypto rails processing: KYC status is immediately available for transfer creation
- Higher conversion rates: Reduced friction leads to better completion rates
- Token refresh capability: Handle token expiration seamlessly with new PATCH calls
Example Request with ShareToken
Crypto Rails Integration Pattern
Typical Workflow:
- Create Customer:
POST /v1/customerswith minimal data - Generate SumSub Token: Obtain shareToken from SumSub with short TTL
- PATCH Customer:
PATCH /v1/customers/{id}with shareToken in body - Token Refresh: Repeat PATCH with new shareToken when current one expires
Integration Notes
- Generate the
shareTokenfrom your SumSub integration before making each PATCH request - The shareToken must be valid and associated with completed KYC verification data
- Important: Due to short TTL, you'll need to make multiple PATCH calls as tokens expire
- This pattern is specifically designed for crypto rails where KYC verification is required for transfers
- Each PATCH call can include other customer data updates alongside the shareToken
