Hi,
I am building a whatsapp based chatbot in chatfuel, and currently trying to connect it with chatgpt via zapier. I am stuck in the last step of updating the attribute back into chatfuel. I am trying to use the “Update Subscriber” action, but it required using the messenger ID, which is nonexistent (since the chat is whatsapp based). I tried using the whatsapp_user_id, chatfuel_id, and a few other ids that I was able to find via the “find subscriber” action, but all failed. What parameter should I use?
