title: Neon CRM API v2
description: >-
Neon CRM API v2 is a RESTful, JSON-based rebuild of Neon One's legacy API
v1, first launched in 2019. It exposes constituent accounts, households,
donations, pledges, recurring donations, campaigns, memberships, events,
custom fields and custom objects, orders and the online store, volunteers,
and webhook subscriptions. All requests use HTTP Basic Authentication with
the organization's Org ID as the username and an API key as the password.
Neon CRM API v1 and its legacy webhook structure are scheduled to be
retired on July 11, 2026; this document covers API v2 only. This is a
representative subset of the full v2 surface, grounded in Neon's public
developer documentation and version release notes (v2.0 - v2.11), not an
exhaustive mirror of every documented endpoint.
