Add Bank Account to Buyer

1. First, create a new bank account for your buyer:

POST to https://sandbox-api.cpxenterprise.com/buyer/v1/buyer/{buyer.id}/bank

{
 "accountType":"checking",
 "accountNumber":"XXXXXXXXX",
 "routingNumber":"XXXXXXXXX"
}

"8a3f3819b71e4e0db939d8950369f25dedad5a95c26b6015b1d93ec048bf902f"

This response string represents your new "bankAccount.Id." You can retrieve your bank accounts within your buyer object by performing a GET to https://sandbox-api.cpxenterprise.com/buyer/v1/buyer/[BuyerId]

2. Now, update your Buyer's ACH settings with the bank account's "id" (API) or token (UI) value as your "bankAccount.Id":

PUT to https://sandbox-api.cpxenterprise.com/buyer/v1/buyer/{buyer.id}

{
  "ach": {
  	"bankAccountId": "{bankAccount.Id}", // "id" returned from previous post, or, another bank account you have established in your Buyer profile
  	"billing": "GOOD_FUNDS", // GOOD_FUNDS is required for ACH
  	"debitMethod": "Debit for Each Transaction", // or "Debit by Batch"	
		"delayDays": 6 // May also be left out of the payload to default to the Institution Default value. 0-7 are other valid values.
  },
  "achEnabled": true,
  "associatedInstitutionId": "{InstId}",
  "associatedInstitutionName": "{InstName}",
  "bid": "{BID}",
  "id": "{Buyer.Id}",
  "name": "{BuyerName}",
  "achRequested": true
}

{}

You may now check that your ACH was updated with the correct account by executing the following request:
GET to https://sandbox-api.cpxenterprise.com/buyer/v1/buyer/{buyer.Id}/bank/default/ACH

{
    "billing": "GOOD_FUNDS",
    "debitMethod": "Debit for Each Transaction",
    "delayDays": 6,
    "bankAccount": {
        "accountNumber": "****1215",
        "accountType": "checking",
        "id": "{bankAccountId}",
        "routingNumber": "****0052"
    }
}
