Merge

Merge is an integration platform that enables product and engineering teams to embed and manage customer-facing integrations through a single, unified API. Its primary purpose is to simplify how B2B SaaS companies, enterprises, and AI-driven products connect to hundreds of third-party systems across HRIS, ATS, CRM, accounting, ticketing, and other categories. By abstracting away the complexity of individual APIs, authentication flows, and data models, Merge allows teams to ship and maintain integrations significantly faster and with less engineering overhead.

Merge provides a unified data model for each integration category, standardized webhooks, and robust data sync capabilities, so developers can read and write normalized data without handling each provider’s unique schema. It offers pre-built connectors to a large catalog of SaaS applications, production-ready OAuth flows, and granular logs for monitoring and troubleshooting. Admin and agent tools include dashboards for integration health, error inspection, and support workflows, enabling non-engineering teams to help manage customer integrations. Merge also supports advanced features such as field mapping, passthrough requests when raw provider data is needed, and robust sandbox environments for testing.
