Generates a direct debit request link that can be sent to, or shared with a customer, digitally. The customer will be sent a link to complete the signing of the direct debit request.
If your customer doesn't have a valid email and mobile number, your request will fail and an appropriate error will be returned. You will need to update your customers details using the customer endpoint to include an email and mobile number.
