Creating Invoices
To create invoices, add either the Adjustable Price or Fixed Price block to a page or post:
- Navigate to the page or post where you want to add the payment block.
- Click on the + button or type / to add a new block.
- Search for Adjustable Price or Fixed Price in the block library.
- Click on the block to add it to your page or post.
Once the block is added, you can either email a link to that page to a customer or include a link in an invoice sent from your accounting software of choice, such as QuickBooks, Xero, Zoho, FreshBooks, or Harvest.
The customer will need to have or create an Amazon account to make the payment. Once the payment is made, it will be processed by Amazon and the funds will be transferred to your linked bank account.
For more information on how to set up and manage your Amazon Pay account, please refer to the Amazon Pay Help Center.
Receiving Payments
To receive payments, connect the plugin to your Amazon Pay account using one of the methods the under WP Admin > Pay Invoices With Amazon > Settings:
- Connect Automatically: This is the easiest and most secure. Click the Connect Amazon Pay Account button to log in with your Amazon account and have credentials configured automatically.
- Send Public Key: Copy-and-paste a plugin-generated Public Key into Amazon Integration Central, then copy-and-paste the returned Public Key ID.
- Receive Private Key: Generate a Private Key in Amazon Integration Central, then drag-and-drop the downloaded file onto the Settings field and copy-and-paste the Public Key ID.
Once payments are processed, individual payments will be authorized by Amazon within 24 hours. After that period, click the linked «Reference ID» for the payment to go to Seller Central. Clicking «Collect Payment» in Seller Central will transfer the authorized funds.
Further information can be found at Finding your Amazon Pay keys and IDs and in the GitHub repository.
Using as a Shortcode
While the blocks provide a visual preview if using the WordPress block editor, a shortcode is also available for use in the block editor, classic editor, or various layout plugins. The below examples can be copy-and-pasted for testing or custom configuration:
Payment form where customer sets the amount:
[piwa]
Payment button where the amount is $100.50:
[piwa 100.50]
Payment button where the amount is $100.50 and the title is Business Consulting:
[piwa 100.50 "Business Consulting"]
Payment button where the customer sets the amount and inputting an invoice reference number is required:
[piwa input-invoice]
Long-form to display a payment button set to $100.50 for Business Consulting:
[piwa amount="100.50" title="Business Consulting"]
Developer Notes
piwa() can be called with an array of arguments in plugins, mu-plugins, templates, or a theme’s functions.php.
The below example adds payment buttons of various types at the end of Post content if various Categories are assigned.
The existance of Plugin Name: makes it possible to place it in wp-content/plugins/ or a folder within wp-content/plugins to activate or deactivate within WP Admin > Plugins . If placing within a theme’s functions.php or another file that already opens with <?php , the first line <?php should be removed to avoid errors.
<?php
/**
* Plugin Name: Pay Based on Category
* Description: Display a message with payment buttons on Posts depending on assigned Category. If all the categories are assigned, all the buttons and messages will be added.
