How to collect all messages in one messenger?

Question

Messengers

Actually, a question.
I have recently had a need to conduct a lot of dialogues on social networks.
There are many social networks, even several accounts in one social network.
I am looking for ways, tools, solutions, to conduct dialogues in one place.
Or at least receive notifications in one place so that you can go and chat.
Facebook, Vkontakte (several accounts), Odnoklassniki (several accounts), Instagram (several accounts), Skype, Telegram, Viber, WhatsApp.

Answer 1

Haven't seen anything like it. You are unlikely to meet Votsap, there is no official API, and the author covered the only unofficial one from mgp25 (like so). The rest does not interfere with writing in the same php and reducing for example in telegrams

Answer 2

Whatsapp has a custom API. On marketplace. True, it only knows how to send messages.
