User creation

This method provides functionality of:

• creating user

• updating data of a previously created user when specifying the same clientId. The sent parameter values overwrite the previous data.

When depositing, a webhook, is sent to the user's personal address, to the depositWebhookUrl specified in the request. When withdrawing (the common method of "Make withdrawal" / make-withdrawal) from a personal address, a status of this withdrawal will be in response.
