Use Subscription for Payment Plan / Installments

Is it possible to use Subscription for Payment Plan / Installments. Meaning, i want to have 3 payments of X amount of money. I will provide a start date, end date and amount.

If you’re not wanting it to be recurring, then it would be better to just create an invoice. You can tell the API how many payments it will be broken into and how much is expected per payment: https://developer.squareup.com/docs/invoices-api/overview.
