Web development payment gateway

Hi,

I have a job implementing 2 new Payment gateway. It's called Reepay.

The platform is similar to Just Eat or Foodpanda.

https://github.com/reepay/reepay-checkout-php
https://docs.reepay.com/reference
https://docs.reepay.com/reference#api-examples

https://docs.reepay.com/docs/new-web-shop

The stack is a mix of Laravel & Vue, there is already one other payment gateways programmed. This needs to be added as another possibility based on a setting in the database.

We need this:
1. https://docs.reepay.com/reference#createchargesession
2. Call the Reepay Checkout as a Window
3. Instant settlement (settle=true), this must be configurable
4. The parameter key needs to be included to avoid multiple settlements on errors.
5. Payment methods: visa, visa_elec, mc, mobilepay, swish, vipps, diners, maestro, applepay, googlepay
6. We need to pass on an additional custom variable called shopId (our local merchant id).
7. Follow the principles of our already implemented gateway, but some things might be a bit different with this gateway. Questions are always OK.


The other one we need implemented is https://paylike.io/.

Thanks
