Trigger bot using Orchestrator API via Postman

I’m trying to trigger unattended process via postman api. UiPath Assistant is installed on virtual machine. When I hit send in postman I’m getting this error → Robots without credentials cannot run processes that require an interactive session.

Can anyone have idea, what’s wrong with this?

First check that you can start the same process with same settings from Orchetrator manually.



I guess you did not provide credentials in orchestrator


Which one? Windows or any other

Hello @pravin_bindage

Are you able to execute task from orchestrator with that robot?


No it stuck at pending stage. I think i’m not assigned unattended license

Hi pravin,
Robot credentials means we have to pass the robot value.

it is two Types

  1. Robot value- You can use same value with one or more bots.
  2. Value per bot - you have to set each value per each bot .



Windows credentials in which you have connected robot

Hi Pravin,
Here we set up the Redirect URL using Postman, I need to use this in actual UiPath project, how do I set up the redirect URL.
I can not use simple ‘Application Scope’ as I need to query ‘Alerts’, I need to set up User Scope and use it in UiPath Project.

Sorry @Kanad_Mehta I’m also looking for same. I don’t have any idea about it.

If using in UiPath you can directly use orchestrtrator http request activity…


Hi Anil,
I need to query another Orchestrator from the one bot is running on.


Thats a weird request.May I know what is the use case?
