Use this API to create a new subscription. After a successful request, the response will include a payment link that you must redirect your customer to in order to complete the subscription setup.

Endpoint

  • URL: https://demo-api.frontpayment.no/api/v1/connect/subscription/submit
  • Method: POST ([docs.frontpayment.no][1])

Authentication
