### 1. Update the button-rendering code

In the button integration code, remove the `sandbox` parameter: 

<ul id="profileTabs" class="nav nav-tabs">
  <li class="nav-item"><a class="active nav-link noExtIcon" href="#usButtonTab" data-toggle="tab">US</a></li>
  <li class="nav-item"><a class="nav-link noExtIcon" href="#euButtonTab" data-toggle="tab">EU</a></li>
  <li class="nav-item"><a class="nav-link noExtIcon" href="#ukButtonTab" data-toggle="tab">UK</a></li>
  <li class="nav-item"><a class="nav-link noExtIcon" href="#jpButtonTab" data-toggle="tab">JP</a></li>
</ul>
<div class="tab-content">

### 2. Update API endpoints

Change API endpoints from sandbox to live:

<table width="100%" border="1">
    <tbody>
        <tr id='QSL9CAfhK08'>
            <td id='s:QSL9CAfhK08;QSL9CAME936' style="vertical-align: top; font-weight: bold; width: 10%;" class='bold'>Region
                <br /></td>
            <td id='s:QSL9CAfhK08;QSL9CA4Ukpw' style="vertical-align: top; font-weight: bold; width: 45%;" class='bold'>Sandbox base API endpoint
                <br /></td>
            <td id='s:QSL9CAfhK08;QSL9CA5RJCe' style="vertical-align: top; font-weight: bold; width: 45%;" class='bold'>Production base API endpoint

        </tr>

### 3. Review the pre-launch checklist

Ensure that stakeholders within your business have the proper user access permissions for <a href="http://sellercentral.amazon.com/" target="_blank" rel="noopener noreferrer">Seller Central</a>, and are aware of the launch date. Review the pre-launch checklist below to ensure a successful launch.

#### Account configuration

* Ensure that you have completed Amazon Pay merchant account registration, and you’re ready to process payments in Production.
* Ensure all domains have been added to Seller Central. See [Add domains to Seller Central](../amazon-pay-checkout/v1-get-set-up-for-integration.html#2-add-domains-to-seller-central) for more info.
* Add your logo in the Login with Amazon application to maintain a seamless checkout experience. Note that the logo will be automatically resized to 50 x 150 pixels.
* If you're using IPNs to handle asynchronous processes, add production IPN endpoints. See [using IPNs](../amazon-pay-checkout/v1-set-up-instant-payment-notifications.html) for more info.

#### Optimize the buyer experience

* Ensure that the Amazon Pay button appears above the fold on cart and checkout pages.
* Reduce checkout friction by placing the Amazon Pay button at the start of checkout, before buyers are asked to manually enter their details.
* Verify that the Amazon Pay checkout experience is optimized for both desktop and mobile experiences.
* Check that [buyer communication](../amazon-pay-checkout/v1-buyer-communication.html) provides accurate information.

#### Common integration issues

* Some Amazon Pay transactions are processed asynchronously. This means that Amazon Pay will return a pending response and the object will be in an Pending state until processing is complete. If applicable, make sure that you’re handling [asynchronous processing](../amazon-pay-checkout/v1-asynchronous-processing.html).
* Amazon Pay returns a string string for buyer name. Make sure you’re parsing the buyer name correctly. Note that some buyers may only provide a single name, e.g. “Jane”.
