NinjaOne (NinjaRMM) MSP API
NinjaOne (formerly NinjaRMM) REST API for endpoint management and MSP platform. Enables AI agents to access device inventory and health data, manage patch status and deployments, trigger remote monitoring alerts, manage organizations and policies, retrieve software inventory, access backup status, handle ticketing and automations, and integrate endpoint data with PSA and documentation systems.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Endpoint management platform. SOC2, ISO27001, GDPR. OAuth2 with scopes. US/EU data residency. Best security posture among MSP platforms.
⚡ Reliability
Best When
An MSP using NinjaOne wants AI agents to automate endpoint health monitoring, patch compliance reporting, device policy management, and integration with ticketing and documentation tools.
Avoid When
AUTHORIZED USE ONLY: Remote device access and script execution requires strict authorization. NinjaOne provides broad endpoint control — treat API credentials as highly privileged.
Use Cases
- • Retrieving endpoint health and patch compliance data from IT operations agents
- • Managing device policies and automation triggers from endpoint management agents
- • Monitoring backup job status from data protection agents
- • Integrating device inventory with PSA ticketing from MSP workflow agents
Not For
- • In-house IT without MSP-style multi-client endpoint management
- • Network infrastructure management without endpoint focus
- • Enterprise ITSM without managed service RMM capabilities
Interface
Authentication
NinjaOne uses OAuth 2.0 client credentials for API access. Scopes control access to devices, organizations, policies, and reporting. Well-documented OAuth flow. API available to all NinjaOne customers.
Pricing
Austin, Texas company, founded 2013. Rebranded as NinjaOne in 2021. One of fastest-growing MSP platforms. Strong API documentation compared to legacy MSP tools. 17,000+ MSP customers.

Known Gotchas
- ⚠ AUTHORIZED USE ONLY: Broad endpoint control — treat OAuth credentials as highly privileged
- ⚠ No public MCP server — REST API with OAuth2 (scoped)
- ⚠ 1200 requests/minute rate limit — generous for bulk device queries
- ⚠ US/EU data residency options — verify for international MSP operations
- ⚠ One of best-documented MSP APIs — good starting point for MSP integrations
- ⚠ Device actions (script execution, restart) are irreversible — implement human-in-loop for risky operations
