Session references on quotes

August 28th, 2026

sessionReference groups the quotes for one order, cart or checkout. Send the same value on every quote in a session and you can match them back to your own records.

What's new

  • Optional but recommended on all three quote endpoints: POST /quotes, POST /quotes/carbon and POST /quotes/nature. The response echoes back whatever you send.
  • Any value unique to the session works, up to 255 characters. Do not include personal data.
