Receive Payments

Now that your node is set up and can interact with Ethereum (whether directly or through the Layer-2 networks), you can start using Hub20 to automatically accept transfers as payment.

To be able to work as a payment gateway, Hub20 provides the following functionality:

• It lets users create stores as the main point of interaction between the hub and the people that want to make payments
• It provides an API for those creating integrations to create payment request on behalf of the stores. This is the Checkout flow.
• For every payment request that is created, the hub will respond with the routes that are available to complete the payment. Every route is a complete description of a payment method and what is required of the payer as a way to fulfill the payment request. For blockchain requests, a route will have information about the token and the amount that was request, the address that the payment should be made to as well as period (represented by a block interval) where that the route is valid. For Raiden payments, a route will include the token, its amount, and a payment identifier, an unique numeric code that can be set by the payer on their own Raiden wallet.
• It will check on the background for any events on the networks (blockchain or Raiden) and relay any new information to the payer. If a transfer is made on the blockchain that matches any of the provided routes, the payer will receive a notification that the payment has been detected. After a confirmation period (10 blocks for blockchain transfers, instant in the case of Raiden), the user is again notified that the payment is confirmed.

To interact with the all of checkout functionality from your site where you want to accept payments, we have developed checkout20, a vue.js based set of components that can be run on your site. You will need to create a store and take note of its id and public key.
