To learn about the Amazon FPS end-of-life plan and for information about migrating to Login and Pay with Amazon, read our FAQ." We were aware of it, we asked them about a testing account be we didn't had one so continuing the new amazon integration was impossible. > Do you have a plugin for "Checkout by Amazon"? That is the Amazon service I have. No, But if you can have the developer documentation about that service and if you can temporary share with us your account so that we can do some testing, we'll be able to develop another Amazon during the next months.

Since Hikashop doesn't have this payment method we are experience lower than expected sales upon launch of our new site. Where is Hikashop at with getting this payment method integrated?

So are we saying that the Amazon Payments plugin in Hikashop Business 2.6.0 does not work?

My client suggested using Amazon payments and I looked through the payment methods and saw your plugin so I reported back to him that this was supported, we then spent nearly a day between us setting up an account and trying to make this work only to find we'd wasted our time. I've now got to go back to my client to say sorry this can't be done. A simple way of avoiding this situation would be to update the description of the plugin so that it says the fast pay service is no longer available. I don't have direct contact with amazon but have sent their support a message asking if they can resolve this for you, failing that I'll set up an account of my own that I will share with you if you can give some assurance of timescale to progress this.

That is not true and there needs to be more internal communication at HikaShop. I gave one Philippe Lavocat access to our account months ago and he was working on the app until he said he needed to switch over to working on the new HikaShop update. Now the time has passed and Amazon is no longer using the "Checkout by Amazon" system and switching over to "Login and Pay with Amazon". Therefore all of this work and time has been wasted. I highly suggest HikaShop get on board with the new Amazon payment system since it is so beneficial to companys, at least here in the USA. As I said at the beginning of this topic, our sales increased immensely on our old site when integrated with Amazon. If we can't get a plugin for "Login and Pay with Amazon" we are better off leaving HikaShop and finding a company that can integrate with Amazon. Thank you for your attention to this matter.

Also, as a heads up, ideally we are looking for a "Login and Pay" solution, so customers can use their amazon account to login to Hikashop and then pay.

From what I can see on our project manager software the project was set on hold by Philippe 4 months ago with the reason "waiting update for the developer account from Brady". So it seems there was a problem with the account or something preventing us to move forward.

Because the main trouble to progress is that we must have a website with an SSL certificat. Without it, it will be impossible to develop this plugin... I hope to have some news tomorrow to solve all of this.

An alternative would be to use a self signed certificate which would be ok for testing.. [ www.selfsignedcertificate.com/](http://www.selfsignedcertificate.com/) A lot of hosting environments also let you generate your own certificates or come with default certificates for testing. I have SSL certificates for my live sites but I can't use those for development (because they are live).
