is_amp_endpoint() inside tracking_api_helper.php

    public function insert_pixel( $impression_params ) {
        $body = json_decode( $impression_params, true );
        $pixel_url = $body["pixel-url"];
        if ( ! is_amp_endpoint() ) {
            echo '<img src="' . $pixel_url . '" style="display:none"></img>';
        }
    }

I see you don’t perform a proper function_exists('is_amp_endpoint') before using is_amp_endpoint() so this code may trigger a Fatal Error if AMP plugin is not active.
