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. Perl

use chilkat();

$success = 0;

# 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).

$jsonToken = chilkat::CkJsonObject->new();
$success = $jsonToken->LoadFile("qa_data/tokens/okta.json");
if ($success != 1) {
    print "Failed to load myob.json" . "\r\n";
    exit;
}

$oauth2 = chilkat::CkOAuth2->new();

$oauth2->put_TokenEndpoint("https://{yourOktaDomain}/oauth2/default/v1/token");

# Replace these with actual values.
$oauth2->put_ClientId("OKTA_CLIENT_ID");
$oauth2->put_ClientSecret("OKTA_CLIENT_SECRET");

# Get the "refresh_token"
$oauth2->put_RefreshToken($jsonToken->stringOf("refresh_token"));

# Send the HTTP POST to refresh the access token..
$oauth2->put_VerboseLogging(1);
$success = $oauth2->RefreshAccessToken();
if ($success != 1) {
    print $oauth2->lastErrorText() . "\r\n";
    exit;
}

# 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.
$sbJson = chilkat::CkStringBuilder->new();
$jsonToken->put_EmitCompact(0);
$jsonToken->EmitSb($sbJson);
$sbJson->WriteFile("qa_data/tokens/okta.json","utf-8",0);

print "OAuth2 authorization granted!" . "\r\n";
print "New Access Token = " . $oauth2->accessToken() . "\r\n";
