QuotWay API and webhooks

Read time: 4 minutes. Who it's for: Developers, agencies and operations teams connecting QuotWay to an ERP, CRM, headless storefront, data warehouse or automation tool.

⚠️ The QuotWay API and webhooks require the Enterprise plan ($199/month). A store on an active 14-day trial has full access, so you can build and test before you subscribe. See Plans, trial, and billing.

What is the QuotWay API?

The QuotWay API is a REST API that lets your own systems read and create B2B quotes in a QuotWay store. Webhooks are its push half: QuotWay sends a signed HTTPS request to your endpoint every time something happens to a quote. Together they let a quote flow into the rest of your stack without anyone copying numbers between screens.

• Base URL: https://api.quotway.com
• Current version: v1 in the URL · 2026-10-01 in the QuotWay-Version response header
• Format: JSON in and out. Money is a decimal string ("1250.00") next to an ISO currency code; timestamps are ISO-8601 in UTC.
• Authentication: a per-store API key sent as Authorization: Bearer qw_live_…
• Errors: RFC 9457 problem details with a stable code on every error.
• Machine-readable spec: OpenAPI 3.1 at https://api.quotway.com/openapi.json - import it into Postman, Insomnia or a code generator.

What the API deliberately does not do

Pricing stays with your team. The API can create a quote request and send a proposal that a person has already priced and saved in QuotWay, but it cannot set or change prices, accept or decline on the buyer's behalf, edit lines, or convert a quote to a draft order. Every commercial decision still happens in QuotWay, under your approval policies and price floor.

Buyer personal data is opt-in. A quote returned by the API carries the buyer's name, email, phone, addresses and free-text answers only when the key has the read_customer_data scope, and webhook payloads never carry them. See the quote object.
