Send pending payment

Trigger a pending payment notification to be sent to the given email address. This pending payment will behave in the same way a payment sent manually through the SnapRefund web app behaves. ie) The recipient will receive a notification email for the payment containing a deep link to the Pending Payment. Once inside, the recipient will select their payout method of choice from a list of all of the available payment options for the given sender. If the sender has at least one branding profile, brandingProfileId is required and must be linked to the selected senderBankId. If the sender has no branding profiles, omit brandingProfileId and the payment branding will be null.
