You can have your bot send a message to all your users’ active conversations at regular intervals. This is useful if you want to send reminders, notifications, or other time-sensitive messages to your users.
You will need:

​
Step 1: Setup your Personal Access Token

Since you need to use the Botpress API to send a reminder to all users, you need to set up a Personal Access Token for authentication.

​
Create the token

  1. In the bottom-left corner of the Dashboard, select your profile picture.
  2. Select Personal access tokens, then Generate new token.
  3. Enter a note to remember the token’s purpose—like “Reminders”.
  4. Select Generate Token.
  5. Copy the generated token and store it somewhere—once you leave this page, you won’t be able read it again.

​
Store the token in a variable

Next, create a configuration variable called PERSONAL_ACCESS_TOKEN and store your token in it. This will let you access the token in code.

​
Step 2: Add a Fixed Schedule Trigger

Add a Fixed Schedule Trigger to your bot’s Workflow. This will make sure your reminder sends on a set interval.

You can configure the Trigger to execute at whatever interval you’d like.

​
Step 3: Add an Execute Code Card

Connect an Execute Code Card to your Trigger:

​
Step 4: Apply the custom code

Paste the following code into the Card’s configuration: 
const botId = '<your-bot-id>' // Replace with your actual bot ID (found in the Studio URL)
const botpressApiUrl = 'https://api.botpress.cloud/v1/chat/conversations'
const botpressApiKey = env.PERSONAL_ACCESS_TOKEN

const response = await axios.get(botpressApiUrl, {
  headers: {
    Authorization: `Bearer ${botpressApiKey}`,
    'x-bot-id': botId
  }
})

// Optional: Log the list of conversations
console.log(response.data)

response.data.conversations.forEach((conversation) => {
  const conversationId = conversation.id
  client.createMessage({
    conversationId,
    userId: botId,
    tags: {},
    type: 'text',
    payload: {
      text: "Don't forget to drink water!", // Your reminder message
    },
  })
})
Be sure to replace the placeholder value for botId with your actual bot ID. To find your bot ID:
  1. Open your bot in the Studio.
  2. Get the bot ID from the URL’s path. For example: https://studio.botpress.cloud/THIS_IS_YOUR_BOT_ID/
Once you’ve published the latest version of your bot, it will send reminders to all active conversations at the specified interval.
