This release sharpens documentation and streamlines integrations across our API and B2B features. Highlights include support for additional checkout URLs (buybutton, mcp), clearer field definitions and examples (e.g., order_id as a string, updated_at behavior), and refined guidance for tax provider workflows and product custom fields. On the B2B side, we’ve updated authentication to include the Store Hash in the payload for affected endpoints and shipped targeted fixes to the Catalyst/B2B guides to speed up setup.
