First you need to call

https://developer.ebay.com/api-docs/sell/marketing/resources/promotion/methods/getPromotions

Which will give you a list of promotions along with promotionHref and that can be used as promotion id.

getPromotions always gives 500 error.  getting promotions only allow our products or all products ?

{
"errors": [
{
"errorId": 2003,
"domain": "ACCESS",
"category": "APPLICATION",
"message": "Internal error",
"longMessage": "There was a problem with an eBay internal system or process. Contact eBay developer support for assistance"
}
]
}

I created a multi buy discount on this page

https://www.ebay.com.au/sh/mktv2/promotionmanager/dashboard

and I can see it here

https://api.ebay.com/sell/marketing/v1/promotion?sort=START_DATE&marketplace_id=EBAY_AU

You can add only your products in the promotion.
