Gringotts (:warning: BETA STATE :warning:)

npm version docker image Version (latest by date)

Gringotts is a service which can be used as gateway between your payment provider and for example your SAAS application. It allows you to easily handle customers, subscriptions and invoice generation for your users.

Gringotts

Some (current) opinions

  • Subscriptions are always monthly
  • Subscription-periods start at the first day the customer started the subscription (exp. 2021-01-15 to 2021-02-14, 2021-02-15 to 2021-03-14, ...)
  • Invoices are generated at the end of the subscription-period (exp. 2021-01-15 to 2021-02-14 => invoice is generated on 2021-02-14)

Usage

Container image

The container image can be found at ghcr.io/geprog/gringotts.

CREATE_PROJECT_DATA='{ "name": "TestProject", "mollieApiKey": "123", "paymentProvider": "mollie", "webhookUrl": "http://localhost:4000/payments/webhook", "currency": "EUR", "vatRate": 19.0, "invoiceData": { "email": "test@example.com", "name": "Company ABC", "addressLine1": "Diagon Alley 1337", "addressLine2": "string", "zipCode": "12345", "city": "London", "country": "Germany", "logo": "data:image/svg+xml;base64,...." } }'
