1. Invoicing

An invoice encapsulates the entire payments process. Once the customer has selected Plue as a payment option the next step is for your system to generate a Plue invoice for their payment.

Create the invoice

The first step to initiate the payment process is to create an invoice. This would usually be done once the user has selected Plue as the payment option for the order they wish to pay for.

The core pieces of information required to create an invoice are:
  1. The total amount to be paid in your base currency
  2. Return url: When the user has completed their off-site payment this is the url they should be redirected back to.
  3. An optional “reference” field which ideally should match an identifier for your order within your e-commerce system
  4. Status: The status of the invoice which should be set to “initiated”

Redirect customer

Once the invoice has been created the user needs to be redirected to the off-site payments page to handle choosing further payment options and making the payment. This is done after receiving the redirect_url field and sending the user directly to this link on successful invoice creation.

When a user has completed payment they will automatically be directed back to the url defined in the return_url field.

Cancelling invoice

In the case where an invoice is no longer valid the status can be PATCH’d using the following endpoint:

PATCH the endpoint with the new cancelled status and this will stop the user from viewing/interacting with the invoice.
