Hello @Anilket26 

Try to add the below code in install file .

$shop = "shop url";
$api_key = "your api key";
$scopes = "read_orders,write_products,read_products,read_product_listings,write_script_tags,read_themes,write_themes";
$redirect_uri = "generate token file path"; 
$install_url = "https://" . $shop . "/admin/oauth/authorize?client_id=" . $api_key . "&scope=" . $scopes . "&redirect_uri=" . urlencode($redirect_uri);

// Redirect
header("Location: " . $install_url);
die();
