Merge.dev

Unified API platform that lets you build once and access hundreds of customer-facing integrations across HR, payroll, accounting, ticketing, CRM, ATS, file storage, knowledge base, and chat. Third-party data is normalized into common models so you can sync between your product and downstream systems through a single API instead of maintaining individual connectors.

Merge is used by enterprises such as Ramp, Bill.com, Perplexity, and Mistral AI, and stands out by taking on connector maintenance so engineering teams avoid per-integration work. The platform includes Merge Agent Handler for AI agents needing secure access to pre-built tools across customer systems.

Key capabilities:

• Single Unified API for HRIS, accounting, ticketing, CRM, ATS, file storage, knowledge base, and chat
• Merge Link for embedded user-facing integration setup with Magic Link support
• SDKs for Python, Node, Ruby, Go, and Java
• Webhooks, passthrough requests, and remote data for custom fields
• SOC 2 Type II, ISO 27001, HIPAA, and GDPR compliance

Teams use Merge to fuel RAG and enterprise search by syncing customer data, implement auto-provisioning from HR employee data, reconcile vendor payments with accounting platforms, and power AI agents and automations. The API supports pagination, idempotency, async operations, and MCP for agent tooling.
