Question

Is it possible use opt-in for WhatsApp for the same number on Facebook and Instagram?


pynchon

Hi!

We’re trying to keep as many doors open as possible for leads to sign up to our event and then receive a message on WhatsApp. But what I’ve noticed is that if you sign up on one platform and then on another, your account will only have opted-in for WhatsApp on the first platform. 

Usually, I wouldn’t mind this, but our audience is older and would sign up twice on different social media platforms.

Is there a way to perhaps fix this issue?

Hi, ​@pynchon!

Without more information it's hard to understand what exactly you are looking for.

But maybe you could use some automation tool (Make, Zapier, n8n...) and use Manychat's API to create a subscriber at the moment some lead subscribes via a landing page (if you're collecting phone numbers there).

 

If you need some help to set something like this up, feel free to contact me. 😉

Hi Fabio! Sorry for such a late reply. 

I was kinda thinking about people who respond to a post inviting them to subscribe to an event, and instead of leading them to a landing page, we collect their info (especially phone!) through the chat. If that person has given me their number on Instagram and then again on Facebook, will they have opted-in-for-wpp through both channels or just one? In my experience it appears that it only works on one channel. 

Thank you!

I see… 

Just the first one will receive the number as WhatsApp ID.


You can make a simple test:

Use Data Collection to get the phone number and enable saving it as WhatsApp ID:

 

Then test it with two different accounts sending the same phone number.

 

Just the first one will receive the “WhatsApp opt-in”.
