I have created a new campaign in Facebook Ads, where I selected 

Partner app

Use an existing message sequence from a partner messaging app. You can select the sequence or enter JSON code.

Message flow

FE Flow (Manychat)

in short, i selected partner app and then manychat and selected my automation.. however, i’ve spent already $45 and i didn’t get any chats,  my ads are ultra high CTR… it seems like manychat isnt triggered

how can i troubleshoot this?

i am wondering should i use JSON instead? if yes, where do i get the JSON for my automation?
