I'm trying to create a plugin for Shopify that adds another alternate payment option.
Unfortunately, I have only found ways to add a manual payment option (which is not what I want).
Could anyone point me in the direction of adding a proper payment gateway option to a users list of alternative payment methods (ie. an option that can be selected from the dropdown).
Here is the solution for everyone (Seeing that this post is so old and no one has replied to it).
The full article can be found at the link below.
Scroll down to the Ecommerce Plugins section and follow the instructions.
If for some reason you can see the page then here are the instructions:
Zapper for eCommerce allows easy payments with the Shopify Plugin; by allowing your customers to scan an interactive dynamic QR code at checkout, and receive a real time payment update.
The Zapper Shopify plugin can be installed by following this link: https://www.shopify.com/login?redirect=authorize_gateway%2F1030428
Once installed, the gateway will need to be enabled via the store admin:
3. Enter your Zapper Shopify Id and POS Token
4. Make sure to leave "Use test mode" UNCHECKED
5. Save your updates
When the customer decides to select a payment method during the checkout process, your customers will be able to select "Zapper" as a payment method.
The Shopify Zapper ID is a combination of your (Zapper) MerchantId and the (Zapper) SiteId, e.g. 1234-5678. You would have received these identifiers when you became a Merchant with Zapper.
If you need to obtain these identification values (forgotten/ lost them) you can get them from:
The ability to retrieve this information are being build into the Zapper Merchant Portal.
