I did have Royal mail integrated with Amazon so that when I sold something on Amazon, it would automatically populate on Royal mail for me to arrange postage etc. However, this changed and I no longer have the integration. I do still have a Business Royal Mail account. When I click to go to the Developer page as per the Royal Mail set up instructions (http://developer.amazonservices.co.uk/) it doesn’t really help or display anything.
Can anyone please help!?
