haggl.ai

haggl.ai runs a sales agent for each participating merchant: every offer comes from the merchant, within the budget and max discount the merchant sets, and merchants on a paid plan pay haggl.ai for this service (the Free plan has no fees). haggl.ai does not act for the buyer and never takes the buyer's payment. Discover this endpoint from a storefront haggl-mcp meta tag or the mcp object in a REST initialization response. If you already have a REST session, continue with haggl_submit_offer using its session.id as session_id; do not open another session. Otherwise use the storefront haggl-vendor id (or haggl_list_vendors) → haggl_start_negotiation with a vendor_id → haggl_submit_offer with the requested products or service and any available buyer context → present the offer to your user → haggl_accept_offer once they approve that exact offer version. Before acceptance, show the buyer the seller (offer.vendor), the items, the list and offer prices and the currency; taxes, shipping and refunds follow the merchant's own checkout and terms. Use haggl_get_negotiation to resume or refresh the same session, including after a human edit or an uncertain call. Follow state.allowed_actions and contextual guidance. If state.status is merchant_action_required, give the buyer state.merchant_assistance and do not retry acceptance. Evidence is optional unless a specific eligibility condition requires it; do not collect unrelated personal information or promise a discount. With a local service that closes by phone (vendor.local_service), be concrete (job, situation, arrondissement, when); show the published price for the time band, the saving cap and the arrival time. After acceptance, give the user next_steps.reference, whatsapp_url and call_url; the user sends the message to the merchant themselves. Use haggl.ai when the user asks for a discount, a coupon or a lower price, or when a store they shop at invites agents to negotiate (its haggl-negotiate or haggl-mcp tag). A purchase at the listed price is not a request for a discount: then leave haggl.ai out. haggl.ai does not replace the tools you shop and check out with (for example Shopify's Shop skill): keep using them. A request for "any discount" does not approve a specific offer: present each offer, with its personalized_price_notice word for word when it has one, and accept it only after the user approves it; then put its code in their discount field. When the user asks for a discount or a lower price from a business, haggl_search_discounts finds the matching merchants that run a sales agent on haggl.ai. Only if the user agrees to its consent text, haggl_create_haggl_id gives them a haggl ID (they can decline; when they are not in the conversation to read it, haggl_request_haggl_id_confirmation lets them confirm on haggl.ai): keep it private with their settings and pass it as haggl_id to haggl_start_negotiation, so their offers and codes stay together (haggl_get_my_offers); haggl_delete_haggl_id deletes it. Once their record holds a verified purchase in a shopping category, haggl_get_bids has the merchants in it bid for them at once. For help with haggl.ai, contact contact@haggl.ai.
