To enable recurring payments for Paypal, please make sure you PayPal account is supporting recurring payments. If you don't have an account manager at PayPal, we kindly suggest to open a ticket at PayPal and ask for the following:
- Enabling Reference Transaction support
- Enabling permissions to allow Adyen to make calls on behalf of a 3rd party (in this case HTC)
When your PayPal is configured accordingly, please use these payment fields for submitting recurring payments.
