Update customer using REST API

[JIrawl]

Currently, the REST API only allows me to create customer.
https://developer.atlassian.com/cloud/jira/service-desk/rest/#api-customer-post

However, i would like to know if there's a way I can update an existing customer using this API ? => change the name, etc.

Furthermore, I also want to create a new customer key/value for this user ? i can do that using the UI, but i need the feature in REST API.

In your scenario, (please try in development first) You can try removing existing customer using Remove Customers and again add customer with new key/value. I do not see rest call for update/put already existed customer in the service-desk rest docs.
