# Overview

> Manage mailing addresses and check settings used for sending physical checks.

Paywint supports sending physical mailed checks as one of its payment methods.\
Before a check can be issued, each user must have:

* A valid **check mailing address**, and
* Optional **check configuration settings** such as custom logo or signature.

This section provides the APIs needed to manage check-related details for your users.

***

## What This API Covers

The Check Management API allows you to:

* Create and maintain a user's **check mailing address**
* Update address details at any time
* Configure check appearance (logo, signature)
* Reset branding back to Paywint defaults
* Support mailed-check payments created through the Payments API

These APIs do **not** send a check directly.\
Checks are delivered through the [Mail Check](/api-reference/payments/mail-check) endpoint inside the [Payments](/api-reference/payments/overview) section.

## When Check Management Is Used

You should manage check settings when:

* A user wants payments delivered as physical checks
* The mailing address changes
* A business wants custom branding (logo or signature) on mailed checks
* You want to reset a user's check branding back to the Paywint default

These settings ensure every mailed check contains accurate address information and optional branded elements.

## Easily manage checks

<Steps>
  <Step title="1. Add the user's check mailing address">
    Call <code>[Add Check Address](/api-reference/checks/add-address)</code> to store the recipient address used for mailing checks.
  </Step>

  <Step title="2. (Optional) Configure check branding">
    Use <code>[Update Check Config](/api-reference/checks/update-config)</code> to include a logo or signature.\
    This step is optional—Paywint uses a default design if none is provided.
  </Step>

  <Step title="3. Update address or branding as needed">
    At any time, you may update the user’s details using the corresponding endpoints.
  </Step>

  <Step title="4. Create a mailed check payment">
    When sending a payment using the Payments API with the **Mail Check** method,\
    Paywint uses the stored address and configuration to issue the check.
  </Step>
</Steps>

## Best Practices

* Always keep the user's check address up-to-date before issuing mailed checks
* Use publicly accessible HTTPS URLs for logos and signatures
* Allow users to preview their check branding inside your application
* If branding is optional for your use case, rely on Paywint’s default settings
