The Payments API enables you to move funds between a Lithic-assigned general purpose account (see Financial Accounts) and an external bank account (see External Bank Accounts). Funds are currently moved via ACH but additional payment rails will be added in the future.

ACH Origination Lifecycle

ACH debit originations undergo three phases in their lifecycle:

Confirmation from Lithic that the ACH request has been received. This is represented as an ACH_ORIGINATION_PENDING event
Acknowledgement from the ACH network that the origination has been received. This is represented as an ACH_ORIGINATION_PROCESSED event
Hold period of 4 business days has passed and the funds are now settled and available for use. This is represented as an ACH_ORIGINATION_RELEASED event

ACH credit originations undergo two phases in their lifecycle:

Confirmation from Lithic that the ACH request has been received. This is represented as an ACH_ORIGINATION_PENDING event
Acknowledgement from the ACH network that the origination has been received. For a credit origination, this indicates the funds are now settled and available for use. This is represented as an ACH_ORIGINATION_RELEASED event

descriptor	Customer-provided description for the payment. May appear in bank statements
events	A list of events that have modified this payment
pending_amount	Pending amount of the transaction in the currency’s smallest unit (e.g., cents for USD). Positive amount indicates the payment, once completed, will increase your balance while a negative amount indicates it will decrease your balance.

status	`DECLINED`, `EXPIRED`, `PENDING`, `SETTLED`, `VOIDED` ,`RETURNED`
token	Globally unique identifier for this payment
updated	Date and time of when this payment was last updated

direction	`DEBIT` indicates funds are moving from an external bank account to a Lithic-assigned virtual bank account number. `CREDIT` indicates funds are moving from a Lithic-assigned virtual bank account number to an external bank account
source	`LITHIC` which indicates a manual payment initiated by Lithic, `CUSTOMER` which indicates a payment initiated by customers
method	`ACH_NEXT_DAY`, `ACH_SAME_DAY`
