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.
