Instant Payments


Instant Payments refer to the payments that can be transferred and posted 24/7 to or from a customer’s account. The credits originated by a sender clear in "near real time" through a centralized network.

Currently, Newline's Instant Payments offering utilizes The Clearing House (TCH) network, commonly referred to as the Real Time Payment (RTP) network.

Account Funding

Sufficient available funds must be present in your source Synthetic Account when you submit an Instant Payments credit transfer. Newline will debit the funds from your account during the credit origination process. If sufficient available funds are not present, the credit transfer will be rejected.

NoteIf you are using a non-instant payment to fund your disbursement account, such as a Wire or ACH, please remember that these will not process after cutoff times, on weekends or on bank holidays. Please ensure you have appropriate funding in your account to cover these time periods when credit of funds via these methods is not possible.

Reject Codes and Descriptions

An Instant Payment may be rejected by the both Newline and RTP network for a number of reasons. In the event of a rejection, the Instant Payment will fail. Newline will return ERR codes (see API Errors for the codes and descriptions). If you need further assistance resolving an error, please reach out to your Newline Specialist or Relationship team for more information.
