neon_create_account
Create an account
Create a constituent account: an INDIVIDUAL (a person) or a COMPANY (with company_name, plus an optional primary contact). Neon's Account Match may merge it into an existing account with the same name and email, so check neon_list_accounts by email first. Returns the new id. Neon: POST /accounts.

neon_create_activity
Log an activity
Create an activity — log an interaction with a constituent (call, meeting, note) or schedule a task. Needs a subject, a start date, a time zone id (neon_list_properties name=systemTimezones), a status id (name=activityStatuses) and a priority; link it to accounts and assign it to system users. Returns the new id. Neon: POST /activities.

neon_list_search_fields
List search or output fields

neon_search
Search records
Report-style search over accounts, donations (includes pledges and pledge payments), activities or events. Give filter criteria (field + operator + value), the output columns to return (standard field NAMES as strings, or custom-field IDS as integers — both from neon_list_search_fields), and 0-based pagination. Results come back as searchResults rows keyed by output field name, plus pagination totals. Neon allows only ONE concurrent search per endpoint. Neon: POST /{resource}/search.
