Extract Google API Bearer Token

Help Studio
1

Hi All,

I have been trying for some time now to use UiPath to generate a Google API Bearer token. This is done automatically by the smart coding done on the Gsuite activity and I have seen a previous post where another user wanted to receive the output token from the Application Scope authentication so that it can be passed on but due to security concerns, the answer was no.

I find myself in a similar scenario where I would like to use BigQuery to send data to. I have managed to build an automation that can convert a data table into the JSON body needed to insert the data into BigQuery. I have also been able to test this using the Google OAuth2 Playground to generate a Bearer Token and provide this in the header of the API call. However, these are throw away tokens and I need to use a service account instead.

Where I am stuck, and with no programming experience, is constructing the JWT for the service account I want to use, more specifically the Signing of the encoded header and claims set using the p12 key and SHA256withRSA. If I could crack this part (using UiPath or InvokeCode within UiPath) then I would not need you to output the token.

This is what I have been working with: Utiliser OAuth 2.0 pour l'authentification serveur à serveur  |  Google Identity  |  Google Developers

Any help or a point in the right direction would be greatly appreciated

Hi,
Where you ever able to generate a bearer token for use in API calls in UiPath? I’m trying to get google location reviews and I can make it work in Postman but in UiPath I have not yet been able to get the token. I’m trying to use a scope of https://www.googleapis.com/auth/business.manage for the calls.

Share with us some screenshots from Postman in order to see a successful call for an access_token.

Also, you can generate the HTTP code snippet from Postman.

Then, the same HTTP post request should be adapted for the HTTP Request activity in UiPath Studio.

Postman is not the same as UiPath. The API calls have a redirect uri that if I point to postman it does the hand shake and ultimately returns the bearer token. UiPath can’t do that hand shake and when I look at the reply from google in Fiddler It actually is attempting to point me to a Google logon page.
Postman requests is like this:
https://accounts.google.com/o/oauth2/v2/auth?response_type=code&client_id=client_id&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fbusiness.manage&redirect_uri=https%3A%2F%2Fwww.getpostman.com%2Foauth2%2Fcallback
In UiPath I only get the HTML for the Google sign in page…
Google does Not make it easy to call their APIs using http :frowning:

In this case, you can be creative, and create a PowerShell/Python/Bat script that will do all the needed calls in order to retrieve the access_token.
In UiPath you will invoke that process/code that you have created in order to retrieve the access_token and pass it into a variable.

Then, in the end, you can use the HTTP Request activity as normal.

Let us know if this helped.
