Question:
I am trying to set a Get started button on Messenger, but I got error 200. What is this?
Answer:
This error message is from Facebook when you are not granted permissions on the page. Please make sure that you have sufficient permissions on the page you are trying to add a get-started button. If you are the Page admin, try to do Page re-import. Please follow these steps:
Go to Import Social Media → Add pages → Make sure that you checked all permissions
