Only individuals may create a Facebook Profile. However, an individual can use their Profile to create a Facebook Page for a business.
A Facebook user must initiate communication using Facebook Messenger via the business's Facebook Page. A message from the business to the Facebook user will be refused if a user has not initiated contact with the business's Facebook Page within 24 hours.
Facebook Messenger uses its own form of IDs for the Facebook User and the Facebook Page :
- Facebook User (profile) - Page-Scoped ID (PSID)
- Facebook Page (business) - Page ID
The Facebook User will have a Page-scoped ID (PSID) and this is unique for each Facebook Profile. The business can only obtain the PSID of a user when the user sends a message to the business. In Facebook Messenger, the default is for the customer to initiate a conversation with a business.
In order to get started with Facebook Messenger you will need to link your business's Facebook Page to Nexmo.
