You need to link gotomaxx PDFMAILER to your Amazon Payments account to use the PDF Payment integration by Amazon Payments. Click the “PDF Payment” menu item in the PDFMAILER menu. A list with all supported payment providers will be displayed. Click “Amazon Payments”.
A payment function will now be integrated into the document if you have previously linked PDFMAILER to your Amazon Payments online transfer account; otherwise, the set-up wizard will open. Follow the instructions in the set-up wizard.
Step 1 (Creating a new Amazon Payments application)
You have to register a new application in your Amazon Payments account to use Amazon PDF Payment. Simply log in as usual at https://sellercentral.amazon.de. Select “Login with Amazon” from the drop-down field at the top.
On the following page, select “Register new application”. Assign a name (e.g. PDF Payment) and description and set a link to your privacy policy to register the new application. Confirm with “Save”.
Click “Web settings” and then “Edit”. Add the following two URLs under “Permitted return URLs”:
https://portal.gotomaxx.com/pay/aws/return.php
https://payments-de.amazon.com/gp/widgets/hosted/hostedLWAParameter
Switch back to “Amazon Payments” via the top menu.
Go to “Integrations -> MWS Access Key” and select your newly created PDF Payment application. Note down the integration details displayed there. You will need these in the next step to configure Amazon PDF Payment.
Step 2 (Entering Amazon Payments project details in PDFMAILER)
Enter the account details shown online in the second step of the set-up wizard.
Step 3 (Name and purpose of payment)
In this step, you will be prompted to enter your name/company name. It will be displayed on your payment slip and in your customer’s Amazon Payments shopping cart. You can also select a purpose of payment that will be determined automatically. This information will make it easier to attribute payments. You can define up to two payment purposes. We recommend entering at least the invoice number because that is Amazon Payments requirement. The feedback URL specifies to where the customer will be redirected after successful payment (e.g. your website).
Step 4 (Validity and discount)
Activate the QR code function for paper vouchers as standard. Please read the QR codesection for more information. Specify the period of validity of the payment function within a document via “Valid until”. For example: you can set the period of validity in days (e.g. 30 days) if you wish to create a quote with an expiry date.
In the final stage, you can define various discount rules if you would like to offer your customers a discount (via 
“Add another discount rule”). The payment slip in the PDF only ever shows the total amount without discount. The discount is automatically applied to the total amount (depending on the time) when the customer clicks the payment button, ..
Step 5 (Billing)
In the final step, you can specify how gotomaxx PDF Payment should handle billing .
Once you have connected PDFMAILER to your Amazon Payments account, you can insert your first payment slip as described here. You will furthermore automatically receive a security token from our system via email. You will need this token to set up PDFMAILER with Amazon Payments again (or on another computer) with the same email address.
You can restart the wizard at any time via the PDFMAILER “Settings” menu item and select “PDF Payment” to change the configuration.
