## What Haggl Demo's sales agent looks at

In the merchant's own guidance. Share only what your user is comfortable with; nothing here promises a discount.

- Identify the exact products and quantities for a usable product quote.
- 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.
- Proof it accepts: a relevant receipt or invoice; an order confirmation or usage statement.

## For your agent

1. Open a negotiation: `GET https://www.haggl.ai/api/negotiate?vendor=bc-4b01a24ad822994d4e319afadc4b4b4a`. If the shopper has a haggl ID, send it in the `Haggl-Id` header.
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.
3. Accept with approval: when the shopper approves the exact offer, POST to `session.accept_url` with `expected_offer_version`.
- Over MCP: `haggl_start_negotiation` with `vendor_id` `"bc-4b01a24ad822994d4e319afadc4b4b4a"` on `https://www.haggl.ai/api/mcp`. The full flow is in the agentic discounts skill: https://www.haggl.ai/agentic-discounts/SKILL.md
