Facebook adds a one-time notification API that will provide businesses with a method for offering its customers simple follow-up information.
The new Messenger One-Time Notification API is designed for situations where customers may want to be notified about simple updates like price drops of merchandise or changes in the availability of products.
The way it works. “Businesses can send a message to the user asking if they want to be notified on a topic. If the user asks to be notified, the business receives a token and can use this token to send out the notification with the information the user requested at a later time,” says Facebook.
In its endeavour to ensure a quality experience, Facebook is limiting the number of One-Time interactions that businesses can issue to users. Additionally, the API documentation notes that tokens can only be used once and expire within 1 year of creation.
