Hello,

Can you give some more context? Yes you can, but you need to be going through the UiPath Orchestrator, there are API’s to deal with it and you need to have purchased an unattended licence etc.

I assume you are good at C#, you have to call

API endpoint:

https://cloud.uipath.com/your_org/orchestrator_/odata/Jobs/UiPath.Server.Configuration.OData.StartJobs

Payload like this:

Can we pass few input arguments in StartJob Orchestrator api?

Thanks @kuppu_samy. Understood the concept took the input parameters as in argument in the process and published it to orchestrator then used this json as payload in body of startjob and its as success. able to start a job with arguments { “startInfo”: { “ReleaseKey”: “429cf1cc-283c-424f-a935-43f72c2ca719”, “RobotIds”: [121], “JobsCount”: 0, “Strategy”: “Specific”, “InputArguments”: “{"age":33,"trueOrFalse":false,"stringNew":"testing"}” } }

Hello @e0f13150f0c3f376ac845921e

If you are familiar in working with APIs, then you can take a look at the Orchestrator API documentation (Swagger) by accessing the URL:

https://cloud.uipath.com/{your_org_name}/DefaultTenant/orchestrator_/swagger

Can you suggest a skeleton where to put coordinates?
For example chat gpt create this sample code but it doesn’t work:

Can you give me a skeleton of call?

[Jon_Smith]

Yeah no worries bud your English is all good so far.

The Community version is only for learning etc.
If you want to do this for an actual process, you need to purchase a licence.

When I asked for more context, I wanted to know what are your wider reasons for wanting to do it via C# etc, it might not be the best way, there is a reason its not set up for this to work straight out of the box. Can you explain your use case?

You could take a look at the post below.
