API call using HTTP Request activity and JWT that uses current Epoch time

Help Activities

Hey everyone, any help is appreciated.

I can successfully make a POST API call using Postman.com, i need to translate that into the HTTP request in UiPath studio.

One issue I’m struggling to get my head around is that I need to authenticate using a JSON web token, which is easy enough online, but part of the payload within that JWT is ‘iat’ (iat = issued at, it is the current time in UTC in epoch seconds. The token expires within 30 seconds of the current time).

Example:

{
  "iss": "my_serice_id",
  "iat": 1719504660
}

So I need to generate a new JWT and use it within 30 seconds of its generation each time i wish to use the API service.

My question is, how do i generate the JWT locally in UiPath studio before implementng it into the HTTP request?

Hope I’ve explained myself, any questions don’t hesitate

Hi,

Im generating the JWT as part of the ‘Authorisation’ tab in Postman:

I can generate epoch time in UiPath studio, the problem is getting that into a JWT within studio. Unless the HTTP Request activity wraps up headers as a JWT for me?

Got you…I believe you need to go with .net code

Thanks for that.

I have a further Q, can this .net framework/code be ran natively in UiPath studio or do i need Visual Studio installed?

Thanks

You don’t need Visual Studio.

Thanks for the reply.

So if I use an invoke code activity I can copy the vb/c# code into it and it will run within UiPath? do i need any additional framework or libraries?
