How to customize portal URLs for Stripe and GoCardless

Customizing portal URLs for Stripe and GoCardless integrations allows businesses to control the flow of payment methods and redirects by utilizing the portal_url field associated with each accounting_contact object. These URLs enable customers to manage payment methods and perform related operations through a dedicated user interface. Customization is achieved by appending specific query parameters, such as success_url for redirect destinations and type for designating the action type, to the API calls. For instance, a URL can be tailored to allow customers to add a payment method and be redirected upon completion, with the flexibility to modify the URL behavior through optional parameters. Understanding these capabilities assumes a basic familiarity with the Unified API and an active integration with either Stripe or GoCardless.
