Helix creates transactions of several different types. Each has a specific meaning and implications to funds availability, settlement time, etc. Types are denoted by a set of two tuples. A tuple can denote a source (or destination), an action, or a behavior. Actions are always in relation to the Customer Account. So a DEP tuple represents the action of depositing into a Customer Account.

For example, a RSVDEP is a deposit into a Customer Account from a Program Reserve Account.

Timeline Guide

Each type of transaction can have its own settlement timeline. However, these are the general groupings:

ACH Transactions - If Helix is the ODFI (Originating Depository Financial Institution) for the transaction, it will settle in 2 business days for all ACH transactions unless same-day settlement is specified in the request to /transfer/create. There is an additional fee per transaction but it will settle the same day if it is received by the bank-defined cutoff time.
Internal Transfers - Always settle instantly, whether moving funds from a Customer Account or one of the various Program Accounts.
Debit Card Authorizations - Typically a settlement date a day or two in the future is specified in the ISO message by the network provider. If none is provided, an industry-standard default of 72 hours is assumed.
Debit Card Transactions - Typically settles instantly, unless a settlement date is specified in the ISO message by the network provider.
Debit Card Reversals - Always settles instantly.
