NinjaOne APIConnect NinjaOne without building on its API
NinjaOne has a REST API. Self-serve for customers only; only NinjaOne system administrators can create API client apps (Administration > Apps > API). If you're reading the docs because you need NinjaOne to talk to the rest of your stack, Caddi does that without you writing or maintaining integration code: you show it the job once, and it runs it across NinjaOne and your other tools.

Building on the NinjaOne API vs. having Caddi run it
| The job | Build it on the API | With Caddi |
|---|---|---|
| Getting access | Register an app, get NinjaOne credentials, and manage tokens and refreshes. | Connect your NinjaOne account once. Caddi holds the connection. |
| Writing the integration | A developer maps fields, handles pagination, retries and rate limits, and writes the sync. | You show Caddi the NinjaOne task the way you'd train a new hire. It writes verified code for it. |
| Steps the API doesn't cover | Screens with no endpoint stay manual, or need a separate RPA tool. | Caddi uses a secure, audited browser session where there's no API, in the same automation. |
| The other systems in the loop | Each extra tool is another API, another set of credentials, another integration to own. | One automation runs across all the tools the job touches. |
| Keeping it running | Someone owns the code when the API version, fields or your process change. | Every automation is reviewed before it runs in production, and every run is logged. |
Building on the API is the right call when you have engineers and the integration is your product. When the goal is getting NinjaOne work off someone's desk, the build is the slow part.
What teams usually want the NinjaOne API for
Alert to ticket
Caddi watches NinjaOne alerts, classifies them, and opens the matching ticket in your PSA with the right priority and owner.
Device & patch reporting
Caddi assembles patch and device-health reports from NinjaOne, files them, and notifies the account manager.
NinjaOne API questions
Does NinjaOne have an API?
Yes. NinjaOne has a REST API, authenticated with OAuth 2.0 (authorization code or client credentials). The official documentation is at https://app.ninjarmm.com/apidocs-beta/.
How do I get access to the NinjaOne API?
Self-serve for customers only; only NinjaOne system administrators can create API client apps (Administration > Apps > API).
Can I connect NinjaOne to my other tools without writing code against its API?
Yes. With Caddi you show the NinjaOne task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across NinjaOne and the other tools the job touches. Where a step has no API, Caddi uses a secure, audited browser session in the same automation.
Do I need a developer to automate NinjaOne with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for NinjaOne is reviewed before it runs in production, and every run is logged.
