Act! CRM

Act! is a CRM and marketing automation platform built for small and mid-sized businesses, providing contact and activity management, opportunity tracking, email marketing, and pipeline reporting in cloud (Act! Advantage) or on-premises (Act! Premium Desktop) editions. The Act! Web API is a JSON-based REST API that exposes contacts, companies, groups, opportunities, activities, tasks, notes, history, documents and tenant-defined custom entities across 410 operations, with OData v4 query options ($filter, $orderby, $top, $skip, $select, $expand) on collection reads, multipart batching at POST /api/$batch, a webhook registration API, and a published Swagger 2.0 specification. Authentication is a JWT bearer token minted at GET /authorize from HTTP Basic credentials plus an Act-Database-Name header. The API is deployed per database — either on Act! Premium Cloud or on the customer's own IIS server — so the base URL is per-tenant.

Act! CRM publishes 1 API on the APIs.io network: Act! Web API. Tagged areas include CRM, Marketing Automation, Contact Management, Sales, and Opportunity Management.

The Act! CRM catalog on APIs.io includes 1 event-driven AsyncAPI specification.

  note: Documentation, the Swagger document and the anonymous GET /api/system route are all public and require no account.
    Actually calling the API requires an Act! subscription that includes API access — the API's own error codes 4031 (Subscription
    required) and 4032 (API access permission required) make the entitlement explicit. Act! documents the free Act! Premium
    trial as the route to API access.

  description: 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.
