any tool/script for whatsapp ?

thing is i have traffic source via whatsapp where people texting on my number . so i am getting almost 1000 new people texting on my number daily. i want to export that all contact or some way to save it on my mobile.

actually, i am going to use it with the WhatsApp story feature. like i can post any link with images and texts... as they people texting me on my WhatsApp, they have saved my number already. . now i want to save all the numbers of them in my mobile contacts so my posted stories can be seen by them. (in whatsapp if both added each other in contacts then only they can see the whatsapp status/story ) .

so is there any way to quickly save all the incoming numbers?

If you have a list of those numbers, you can add them to your phone with a simple adb push command of VCF file.
If you don't have the numbers, it can be done from within whatsapp, but it has to be automated by external programming packages as appium.

I think what you need a bot that will control that phone. The bot will add those people as friends, send broadcasts, update a story or will have full conversations with those people.

I've already done that, so, you're welcome to ask any questions.

Is there any software I can use?

Intrested on how to use it
