Okta: Refresh Access Token with the Auth Code Flow

See more Okta OAuth/OIDC Examples

Demonstrates how to refresh a token that was obtained using the authorization code flow. Go

    success := false

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // See Get Okta Access Token using Authorization Code Flow with PKCE 
    // for sample code showing how to obtain an Okta access token using the authorization code flow for native apps (with PKCE).

    if success != true {
        fmt.Println("Failed to load myob.json")
        jsonToken.DisposeJsonObject()
        return
    }

    oauth2 := chilkat.NewOAuth2()

    oauth2.SetTokenEndpoint("https://{yourOktaDomain}/oauth2/default/v1/token")

    // Replace these with actual values.
    oauth2.SetClientId("OKTA_CLIENT_ID")
    oauth2.SetClientSecret("OKTA_CLIENT_SECRET")

    // Get the "refresh_token"
    oauth2.SetRefreshToken(jsonToken.StringOf("refresh_token"))

    // Send the HTTP POST to refresh the access token..

        jsonToken.DisposeJsonObject()
        oauth2.DisposeOAuth2()
        return
    }

    // Load the access token response into the json object 
    jsonToken.Load(oauth2.AccessTokenResponse())

    // Save the new JSON access token response to a file.
    // The access + refresh tokens contained in this JSON will be needed for the next refresh.
