Charge per message application


I want to make an application where a user will need to pay per message they send to a user. Is there a way to control who can send who a message on a message per message basis?

@kopias No we do not have such thing on our system. However, you can take advantage of using either user’s metaData field to store some information (such as message available count) and check this count before a user attempts to send a message
