Frontend Customisation

Q: I’d like to add a Amazon Pay or Login with Amazon button elsewhere on my site

If you are wanting to add one of these buttons to a new location on your site you need to update the XML for the page you want to add it to.

For instance if you wish to add a Login with Amazon button to the category page you would update the following file.

In your theme directory, you would create: app/design/frontend/<your_namspace>/<your_theme>/Magento_Catalog/layout/catalog_category_view.xml

<page xmlns:xsi="" layout="1column" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
        <referenceBlock name="category.products">
            <block class="Amazon\Login\Block\Login" name="amazon_login" after="category.products.list" template="Amazon_Login::login.phtml"/>

Here you are referencing the block category.products and then simply inserting the Login with Amazon button template into this block to be positioned after the block category.products.list

Amazon Pay

If you wish to add a Amazon Pay button elsewhere in your store, you can follow the same process above, using a different template, like so.

<block class="Amazon\Payment\Block\PaymentLink" name="" after="-" template="Amazon_Payment::payment-link.phtml" />

You can position and target which block the button appears in as with the Login with Amazon button. If you need more information on how to position and add new blocks into Magento 2 please see the Magento 2 documentation
