Originations

Overview

An ACH is an entry sent from one bank (ODFI) to another receiving bank (RDFI). The entry can be a push or pull. The information required for a payment varies depending on the SEC code and is governed by the NACHA Operating Rules and Guidelines. The information required for a payment varies depending on whether it is domestic or international.

Domestic Payments

Domestic payments require the least information to originate. For example, to send $100 from a Cross River account to an account at another bank, would be as simple as:

POST /ach/v1/payments
{
  "accountNumber": "1234567890",
  "receiver": {
    "routingNumber": "021000021",
    "accountNumber": "456789000",
    "accountType": "Checking",
    "name": "Bob Smith",
    "identification": "XYZ123",
  },
  "secCode": "PPD",
  "description": "Payment",
  "transactionType": "Push",
  "amount": 10000,
  "serviceType": "Standard",
}

Domestic IATs

Domestic IATs require the same information found in a domestic payment, and in addition another set of fields specific to IAT payments. This set of fields is found in the iatDetails object.

POST /ach/v1/payments
{
  "accountNumber": "1234567890",
  "receiver": {
    "routingNumber": "021000021",
    "accountNumber": "456789000",
    "accountType": "Checking",
    "name": "Bob Smith",
    "identification": "XYZ123",
  },
  "secCode": "IAT",
  "description": "Payment",
  "transactionType": "Push",
  "amount": 10000,
  "serviceType": "Standard",
  "iatDetails": {
    "receiver": {
      "address": "123 Maple St",
      "city": "New York",
      "state": "NY",
      "postalCode": "10025",
      "countryCode": "US"
    },
    "receivingBank": {
      "name": "First Bank of Business",
      "identification": "021214862",
      "idQualifier": "01",
      "countryCode": "US"
    },  
    "transactionTypeCode": "MIS"
  }
}
