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. Rust

// 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 json_token.load_file("qa_data/tokens/okta.json").is_err() {
    println!("Failed to load myob.json");
    return;
}

let oauth2 = chilkat::OAuth2::new();

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

// Replace these with actual values.
oauth2.set_client_id("OKTA_CLIENT_ID");
oauth2.set_client_secret("OKTA_CLIENT_SECRET");

// Get the "refresh_token"
oauth2.set_refresh_token(&json_token.string_of("refresh_token").unwrap_or_default());

// Send the HTTP POST to refresh the access token..
oauth2.set_verbose_logging(true);
if oauth2.refresh_access_token().is_err() {
    println!("{}", oauth2.last_error_text());
    return;
}

// Load the access token response into the json object 
let _ = json_token.load(&oauth2.access_token_response());

// 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.
