Quotes

The Quotes API exposes graph8’s quote-to-cash lifecycle: draft, edit, send (with signing + payment link), duplicate, convert signed-back-to-draft. Backed by a Stripe v4 quotes integration; payment is captured automatically when the recipient pays.

30-second start

List your quotes:

curl 'https://be.graph8.com/api/v1/quotes?status=sent&limit=10' \
  -H "Authorization: Bearer $G8_API_KEY"

import { g8 } from '@graph8/sdk';
g8.init({ apiKey: process.env.G8_API_KEY! });

const { data } = await g8.quotes.list({ status: 'sent', limit: 10 });
console.log(data); // → QuoteSummary[]

g8 list-quotes --status sent --limit 10

Ask your agent: “Show open quotes that are sent but not signed” → tool: g8_list_quotes.

Quote lifecycle

draft → sent → signed → (collected via Stripe payment link)
                    ↘ declined / expired / void

edit-as-draft reverses signed/sent → draft for revisions. Each revision creates a new signing URL.

Create

POST /api/v1/quotes
Content-Type: application/json

{
  "contact_id": 5028106,
  "company_id": 8821,
  "line_items": [
    { "product_id": "prod_platform", "quantity": 1, "unit_price": 499, "recurring": true },
    { "name": "Onboarding", "quantity": 1, "unit_price": 2500 }
  ],
  "currency": "USD",
  "expires_at": "2026-07-15T00:00:00Z",
  "notes": "Includes 90-day money-back guarantee."
}

Line items can reference a catalog product_id (from /quotable-products) or be ad-hoc.

Update draft

PUT /api/v1/quotes/{quote_id}
Content-Type: application/json

{ "notes": "Updated to 12-month commit", "expires_at": "2026-08-30T00:00:00Z" }

Only quotes in status=draft can be updated. Use POST /{id}/edit-as-draft to convert a sent/signed quote back to draft first.

Send

POST /api/v1/quotes/{quote_id}/send
Content-Type: application/json

{
  "recipient_email": "[email protected]",
  "send_signing_link": true
}

Sends a real email with the PDF attached and a signing link. If the quote includes recurring line items, a Stripe payment link is also generated and embedded.

Duplicate / edit-as-draft / delete

POST   /api/v1/quotes/{id}/duplicate          # copies line items into a new draft
POST   /api/v1/quotes/{id}/edit-as-draft      # status: signed/sent → draft
DELETE /api/v1/quotes/{id}                    # draft only

Settings + products

GET /api/v1/quotable-products
# { data: [{ id, name, description, unit_price, currency, recurring }, ...] }

GET /api/v1/quote-settings
# { data: { default_currency, default_tax_rate, payment_providers, logo_url, signature_required } }

Settings come from the org’s Stripe + branding config. Update via the in-app Quote Settings UI (not via API).

Contact / company graph

GET /api/v1/contacts/{contact_id}/quotes
GET /api/v1/companies/{company_id}/quotes

Returns the full quote history for the contact / company.

Webhooks

Subscribe to quote lifecycle events via the Webhooks surface:

quote.sent — email delivered to recipient
quote.signed — recipient signed (and paid if a payment link was attached)
quote.declined / quote.expired / quote.void

Use these to trigger downstream automations (CRM stage move, Slack notification, sequence enrollment).
