Thx @karing PR, with first version https://github.com/colemanw/webform_civicrm/pull/886

rubofvil → created an issue.

Thx Francesc, but in this case Paypal is redirecting and sending the params with _GET and can use `CRM_Utils_System::redirect`

But we need to use a post in a form (with method _POST) like in doc "Formulario de envío de petición" (https://pagosonline.redsys.es/conexion-redireccion.html)

Pd. I tried to manage sending vars via _POST with Curl and a redirect with headers but i din't find a solution with this

In the file
vendor/twig/twig/src/Template.php

The function `ob_start` is avoding the redirect of the Redsys. The Twig is called to load the node (if the the webform is embeded into a node) after `exit` is called.

This patch fix the issue, but isn't a good solution. It's to understand the issue

A porpouse is make a development that in some cases the Twig not render a node or panel,....
