This method uses POST to assign a creative to a deal ID. You can assign the same creative to multiple deal IDs through this endpoint.
Note: You do not need to assign new creative IDs when you are extending a campaign. For example, if you extend an end date or add another flight schedule on the same campaign, you do not need new creative IDs. Creative IDs can be reused across programmatic deals.
