botpress-broadcast

botpress-broadcast

Provides an interface and APIs to schedule and send messages to your bot audience.

**Support connectors: ** botpress-messenger

Get started

botpress install broadcast

The broadcast module should now be available in your bot UI, and the APIs exposed.

Features

Send according to Users timezone

You can decide wether the scheduled time is abolute to the bot's time or to individual users. If no timezone information available for the user, GMT is chosen.

Send as Javascript snippet

Instead of sending text, you can decide the behavior of the sending function and do basically anything. The function will be called for every message (so for every user).

Variables exposed:

• bp botpress instance
• userId the userId to send the message to
• platform the platform on which the user is on

The built-in Facebook Messenger snippets are example of Javascript execution (see UI).

Filtering

You can apply filters to the broadcasts. Filters are small javascript functions that will be evaluated before sending the broadcast to a user. The condition is called for every users the broadcast is scheduled to.

Variables exposed to the filter function:

• bp botpress instance
• userId the userId to send the message to
• platform the platform on which the user is on

The function needs to return a boolean or a Promise of a boolean.

Note: Starting your function with return is optional.

Examples

Send a message only to users on Facebook

["platform === 'facebook'"]

Send a message only to subscribed users

Note: Assuming your bot has a subscriptions table that holds userId and platform

// in your bot's index.js

bp.isUserSubscribed = (userId, platform) => {
  return bp.db.get()
  .then(knex => 
    knex('subscriptions')
    .where({ userId, platform })
    .select('count(*) as count')
    then().get(0).then(({count}) => count > 0)
  )
}

["bp.isUserSubscribed(userId)"]
