How to implement simultaneous sending of data from the form on the site to Bitrix24, to Getresponse and to the mail?

Question

Web development

There is a simple self-written site, from which the data from the forms is transmitted using ajax to a simple mail.php, which sends the data to the mail with something like this script . There are also forms that pass data directly to getresponse, in fact, there is a simple html form with the " https://app.getresponse.com/add_subscriber.html " handler and a hidden field with a list token in the action.

But there was a task to make it so that now everything also gets to Bitrkis24, while also falling to the mail of several employees, and if this is a subscription form, then in getresponse.
It was not possible to do it through the integration, because Bitrkis24 puts all the leads into one list in getresponse, and the chains of letters are tied exactly to which list the lead falls into.

Is it possible to somehow add the script that already sends applications to the mail so that it also transmits all this to Bitrkis24 and getresponse? Or how else can it be done?
