Discounts are used in conjunction with fees and taxes when determining the pricing details for a quote. Any discounts you associate with your quote will be applied first, followed by associated fees, and then any associated taxes will apply.
After you create a discount, you can use its ID to associate it with a quote. To retrieve a list of discounts you’ve created, you can make a GET request to /crm/v3/objects/discount.To view all available endpoints and their required fields, check out the reference documentation.
