Keap
Keap (formerly Infusionsoft, now part of Thryv) is a CRM, sales and marketing automation platform for small businesses that combines contact management, email and text marketing, e-commerce, affiliate management and pipeline automation. Keap publishes two live OpenAPI 3.1 contracts covering 540 operations — REST v2 (399 operations, the Default version) and REST v1 (141 operations, still the only home of REST Hooks webhooks and Appointments) — plus a deprecated XML-RPC surface. Authentication is OAuth 2.0 authorization code with rotating refresh tokens, or Personal Access Tokens and Service Account Keys, all with a single `full` scope. Keap also operates an undocumented but live remote MCP server at https://api.keap.com/mcp secured with OAuth 2.1, PKCE and dynamic client registration, and ships first-party SDKs for six languages generated in lock-step from its own spec.
Keap publishes 51 APIs on the APIs.io network, including Affiliate API, Automation API, Campaigns API, and 48 more. Tagged areas include CRM, Sales, Marketing Automation, Small Business, and E-Commerce.
The Keap catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
Keap’s developer surface includes authentication, documentation, signup flow, pricing, engineering blog, sandbox, API reference, and 50 more developer resources.
