I am using Smooch to integrate Whatsapp and Facebook with my API.
Is there a way to block some users on Smooch side so that my API doesn't get any messages from them anymore or should I do it on my backend side?
In the docs there is mentioned a blocked flag for Client Schema
so it might suggest it could be doable on the Smooch side.
The blocked flag on a client indicates that the user has blocked communication from the business (attempts to send a message to a blocked client will result in a delivery error).
There is currently no way for the business to block communication from a user on Smooch's side, so you'd have to implement that logic yourself
