The premium plan can request a self hosted database. This means the chat records, leads and chatbot user information will be stored in a separate database from ChatCompose.
To enable this feature please provide a MongoDB connection string for a user with write permissions. The records captured by the chatbot will be stored in your own database.
The connection string is usually provided in this format
mongodb://[username:password@]host1[:port1][,...hostN[:portN]][/[database][?options]]
