Act! Web API
JSON-based REST API for the Act! CRM database exposing contacts, companies, groups, opportunities, tasks, activity series, calendar, notes, history, documents, attachments, users, teams, preferences, analytics and tenant-defined custom entities — 410 operations across 31 resource areas. Collection reads accept OData v4 query options; requests can be batched at POST /api/$batch; webhooks are registered through the API itself. The database schema is discoverable at runtime through the MetadataInfo operations because Act! databases are user-extensible. Authentication is a JWT bearer token obtained from GET /authorize with HTTP Basic credentials and an Act-Database-Name header.
