# Collect Customer Information

Enable your checkout page to collect additional customer information, such as Name, Phone numbers, or Address directly within the payment flow. Activated via the request body when creating a checkout session. 

***

### Overview

By default, the checkout page collects only the payment details required to complete a transaction. Merchants can extend this by enabling `collect_customer` in the creation request. When enabled, the configured fields appear as a form step inside the checkout flow before payment is processed.

### How to Enable Customer Data Collection

Pass the `collect_customer` object inside your Request Body to Checkout Page

```json
...
"collect_customer": {
    "name": true,
    "email" : true,
    "phone" : true,
    "address" : true
  }
...
```
