Gringotts (:warning: BETA STATE :warning:)

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.

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)

To create a project on start you can set the CREATE_PROJECT_DATA environment variable to a json string like this:

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,...." } }'
