What Parcelhouse's sales agent looks at

In the merchant's own guidance. Share only what you're comfortable with; nothing here promises a discount.

  • Identify the service, plan or product being considered.
  • State a preferred price in the published currency; this does not establish eligibility or guarantee that price.
  • Explain the practical requirements that make an offer useful.
  • Relevant previous purchases may help explain preferences or repeat demand; no particular discount is promised.
  • Describe expected use with quantities and time period when known.
  • Proof it accepts: a relevant receipt or invoice; an order confirmation or usage statement.

For your agent

  1. If you can only open web pages: open https://www.haggl.ai/agentic-discounts/parcelhouse-demo/offer for the sales agent's opening offer, made without any details about the shopper. The page links to the accept step; open it only if the shopper wants the offer.
  2. 1. Open a negotiation. GET https://www.haggl.ai/api/negotiate?vendor=parcelhouse-demo. If the shopper has a haggl ID, send it in the Haggl-Id header.
  3. 2. Ask. POST to the returned session.negotiate_url with ask (what the shopper wants) and data (what they agreed to share). Email receipts go in data.proofs[].raw_mime_b64: haggl.ai checks each email's signature and keeps a fingerprint of it, not the email.
  4. 3. Accept with approval. When the shopper approves the exact offer, POST to session.accept_url with expected_offer_version.
  5. Over MCP: haggl_start_negotiation with vendor_id "parcelhouse-demo" on https://www.haggl.ai/api/mcp. The full flow is in the agentic discounts skill.
