• As your token is not valid, error 401 is a perfect error-hint. Why would you expect something different? – gratinierer Commented Feb 16 at 20:29
• I am not getting proper response json as it is show here or not, similarly i am getting the error line showing there – Ashok Commented Feb 19 at 4:05

The error message indicates that your API request is failing due to an expired or revoked token (401 Unauthorized). This typically happens when the authentication token used for the request is no longer valid.

You need to implement token refreshing in your Laravel application

use GuzzleHttp\Client;
use GuzzleHttp\Exception\ClientException;

function fetchAccountData()
{
    $client = new Client();
    $token = getToken(); // Function to get the stored token
try {
    $response = $client->post('https://bankul/acctenq/v2/prefetchAccount', [
        'headers' => [
            'Authorization' => "Bearer $token",
            'Accept' => 'application/json',
        ],
        'json' => [
            // Your request body here
        ],
    ]);

    return json_decode($response->getBody(), true);
} catch (ClientException $e) {
    // Check if error is due to token expiration
    if ($e->getCode() === 401) {
        refreshAccessToken(); // Call function to refresh token
        return fetchAccountData(); // Retry the request
    }

    throw $e; // If it's a different error, throw it
}

}

Implement Token Refresh Function

function refreshAccessToken()
{
    $client = new Client();

    $response = $client->post('https://bankul/oauth/token', [
        'form_params' => [
            'grant_type' => 'refresh_token',
            'client_id' => env('BANK_CLIENT_ID'),
            'client_secret' => env('BANK_CLIENT_SECRET'),
            'refresh_token' => getRefreshToken(),
        ],
    ]);

    $data = json_decode($response->getBody(), true);

    storeToken($data['access_token'], $data['refresh_token']); // Store new tokens
}

Store and Retrieve Tokens

function storeToken($accessToken, $refreshToken)
{
    session(['bank_access_token' => $accessToken, 'bank_refresh_token' => $refreshToken]);
}

function getToken()
{
    return session('bank_access_token');
}

function getRefreshToken()
{
    return session('bank_refresh_token');
}

If the API does not provide a refresh token, you may need to request a new access token from scratch. Ensure you handle API rate limits when retrying requests. Use Laravel’s built-in caching or database to store tokens instead of session storage for better persistence. This approach ensures your Laravel app automatically refreshes the token and retries the request without manual intervention.
