# Customer

The **Customer API** stores and manages shopper personal, billing, and shipping details in a single place. Each customer record is identified by a UUID that can be passed to other Verifone services — including Checkout, eCom, and 3D Secure — wherever customer data is required.

{% hint style="info" %}
A customer record is not always required to process a payment. However, providing one unlocks fraud scoring, APM support (PayPal, Klarna, and others), 3DS authentication, and richer reporting in [Verifone Central](https://docs.verifone.com/verifone-central-getting-started/verifone-central/commerce/reporting/orders-transactions-reports).
{% endhint %}

## Quick Start

{% stepper %}
{% step %}

### Create a customer record

Send a `POST /v2/customer` request with the shopper's billing details and your `entity_id`.
{% endstep %}

{% step %}

### Store the customer UUID

The response returns an `id` field containing the customer UUID. Persist this value — you will pass it to Checkout, eCom, or 3DS when processing payments for this shopper.
{% endstep %}

{% step %}

### Use the UUID in downstream services

Pass the customer UUID to the Checkout or eCom API request body wherever customer data is accepted. For 3DS flows, ensure billing address fields are populated on the record.
{% endstep %}
{% endstepper %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.verifone.com/api-reference/open-api-references/customer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
