Updating Cardholder Details

Step 1: Authenticate the Cardholder

Updating a cardholder's details presents a risk of fraud. GPS suggests that you build in two-factor cardholder authentication into your customer app to verify the cardholder's identity prior to allowing them to update their email or mobile phone details.

Step 2: API request to /cardholder

After successfully authenticating your cardholder, you can call the GPS cards endpoint and include the updated details.

Note

There is no separate cardholder endpoint; you will need to update the details for each card held by the cardholder.

A 200 HTTP header response indicates a successful update to the cardholder.
