Please note, this information is specific to the GoCardless for Salesforce integration.
The standard payment pages used are the ones provided by the GoCardless redirect flow:
These may be pre-populated by specifying the relevant details on either the payment or authorisation object before processing.
A custom description field can also be shown on the payment page by filling in the “description” field on the payment or authorisation object.
Note that the “country” field will only be visible on the payment page if the GoCardless account has been enabled for multiple Direct Debit schemes.
Customised payment pages are not yet available. The ability to use your own pages will be provided in a future release.
