# How to create a Customer
### Customers
* Create a customer - POST **customer**
* Update or add details to a client - POST **update**
#### Create customer request example
**Example of the create customer request**:
Pass your account ID as a parameter - "**account**".
#### **Example of the create customer response**:
```json
{
"id": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
"email": "string",

"blocked": true
}
```
The following options are also available to you:
* Block customer - POST **block**\
Allows you to transfer the client to the "blocked" status.\
The client's addresses remain active for receipts.\
The merchant can receive funds to blocked addresses, but receives a notification via webhook that these are receipts from a blocked user. - **CUSTOMER\_PURSE\_FUNDS\_RECEIVED\_FOR\_PURSE** ("blocked": true)
**Funds received at the blocked client's addresses:**
* Are credited to the merchant's account.
* The merchant is notified by webhook with transaction details and the client's status ("blocked").
* The decision on further distribution of funds remains with the merchant and his agreement with the client.
* Unblock customer - POST **unblock**\
Allows the merchant to restore the client to an active state.\
Once unblocked, the client can continue to use their addresses without restrictions.
