Create Credit Auto-Pay Standing Instruction

Use this API to create a new standing instruction for automatic credit account bill payments.

The standing instruction will be set up to automatically deduct the minimum due amount or the full statement balance from either an internal account or external account using ACH on the due date. This ensures timely payments and helps avoid late fees and interest charges.

Supported Account Types:

• Internal Account: Use fromAccountId when isAccountExternal is false
• External ACH Account: Use fromAccountNumber and fromAccountRoutingNumber when isAccountExternal is true

** Behaviour **: A successful response from this API means the auto-pay standing instruction is created successfully for the client's credit account.
