Hi Ya, I was asking because Facebook announced that it will be merging or allowing Instagram Messenger services within FB Messenger, and it will be an update or relaunch. If I have understood their announcement right. Take a look at the link below.

So, I am hoping I can use the platform to message Instagram Messenger customers via your platform once the feature is available. I am not sure if you will have to do anything on your end. However, it will be useful for me to have Instagram Messenger because my customers are teenagers, who use things like Instagram, SnapChat etc.

We work in a bit different way. Your customers stay on your website, and they don't have to use any messenger. And you at the same time can use one of our 3 supported messengers to communicate with your clients. In your case it might be useful one of our add-ons: https://replain.cc/store/mymessengers it adds a link to your Instagram account to let your clients to contact with you there without replain in the middle.
