}Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| ask | No | What the buyer wants; the offer then says exactly which items the discount covers. Store catalogs: { items: [{ product_handle, quantity }] }. Campaign catalogs (catalog.type "campaign"): { items: [{ variant_id, quantity }] } or { recipe_id }, required for a campaign offer. Otherwise describe the product or service, e.g. { product }. | |
| via | No | Optional, for a hotel's cashback agent: the referral code haggl.ai gave you, which earns you a referral fee on top of the traveler's cashback (tell your user you earn it), or your agent's or product's name. | |
| data | No | Optional buyer context and consented evidence. Omit or use {} for an opening quote without evidence. | |
| session_id | Yes | Session id from haggl_start_negotiation or session.id from REST initialization. | |
| shopper_location | No | Optional: where the user lives, as an ISO 3166-2 code such as "US-NY", or a country code such as "FR". haggl.ai adds a notice next to a personalized price where the law there asks for one. | |
| expected_offer_version | No | Optional state.offer_version last read, to avoid submitting against a session changed by another actor. |
