UiPath Orchestrator APIs – Quick Guide

What is API?

API is the acronym for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other.

An example of an API?

When you install and use a mobile app, the mobile app connects to the Internet and sends data to a server. The server then retrieves that data, interprets it, performs the necessary actions and sends it back to your phone. The application then interprets that data and presents you with the information you wanted in a readable way. This is what an API is – all of this happens via API.

To understand it better, Let’s take the real-time case:

When you visit the hotel to book a room, the receptionist will check the availability and present you with the required details like the cost of the room, room type, the number of days the room available to book, etc… as requested. Here receptionist will act as the intermediary as API, this is what an API will do.

What is the use of Orchestrator API?

APIs here are used to interact with the Orchestrator from any third-party application, even from the UiPath Studio/Robot.

Basic functionality which can be achieved through APIs are

• Start/Stop the Job
• Check the status of the Robots
• Create/Modify the Assets
• Create a queue and push the items into the Queue
• Check the Status of the Jobs
• Get the Environment, Process, Robots, Queue, Jobs details and So on…

What will you learn by the end of this Article?

You will able to

1. Authenticate the API
2. Get all the Robots data from Orchestrator
3. Get the state of the Robot
4. Get the all the Process from Orchestrator
5. Get the all the Jobs from Orchestrator
6. Get the all the Releases from Orchestrator
7. Start the Job from Orchestrator
8. Stop the Job from Orchestrator
9. Get all the Assets from Orchestrator
10. Update the Asset
11. Create the Queue
12. Add item to the Queue

Where we need the Orchestrator APIs?

To communicate with the orchestrator and to use its functionality from the third-party application, we need the Orchestrator API’s which helps in creating communication bridge both the Applications.

Note: We have used postman to demonstrate the article

Authenticate:

Request (Post Call)

Response (200 OK)

“result” parameter value will be used for the authorization (Bearer Type) in all the API calls of Orchestrator.

NOTE: By default, the bearer token expires after 60 minutes. You can change the expiry time, by modifying the value of the Auth.Cookie.Expire parameter, in the Web.config file.
