Refresh oauth token for outbound rest call

[Jon Ulrich]

I have an outbound rest API integration with google g suite. The authentication uses an "Authorization Code" OAuth Profile. I am looking for help on how to pragmatically refresh the OAuth token before running the outbound REST call.

did you have to do anything to update the Refresh Token when they expired @Amruta12  ?

Hi Jon,

We did something similar with G Suite. We generated a refresh token from Google OAuth 2.0 Playground, stored it as a system property (refreshToken variable below), and then used this code to obtain a new Access token when needed. 'G Suite Admin SDK' being the name of the OAuth Provider in the Application Registries.

// GlideOAuthClientRequest
var clientRequest = new sn_auth.GlideOAuthClientRequest();
clientRequest.setGrantType('refresh_token');
clientRequest.setRefreshToken(refreshToken);

// GlideOAuthClient
var client = new sn_auth.GlideOAuthClient();

// GlideOAuthClientResponse
var tokenResponse = client.requestTokenByRequest('G Suite Admin SDK', clientRequest);

// GlideOAuthToken
var token = tokenResponse.getToken();
var expiresIn = token.getExpiresIn();
var accessToken = token.getAccessToken();

Robert, this indeed seems the correct way to go, thank you.

Can you provide some guidance on how you obtained the refresh token?

[Jon Ulrich]

Never mind. I think i got it from the playground after authenticating to the playground with my service account
