API: PUT Offer

Altering an existing offer's details


For auditing purposes, most attributes of an offer cannot be updated once submitted to Banyan. However, the expiration date can be extended to a date in the future or ended early. When using this PUT URL to bring the expiration date forward, the date must be greater than current day + 1.


api.banyan.com/rest/v1/offer/{{byn_offer_id}} where byn_offer_id is the offer you wish to update.


As stated above, the only thing to update is the the expiration date.

expiration_tsWhen the offer endsRFC3339YesShould be sent in UTC. If you want the offer to extend for a long period of time, choose a date far out in the future.


    "expiration_ts": "2022-12-20T00:00:00Z"


As you can see, the response is the full offer detail again, and contains the updated expiration date if a successful call was made.
