The Runtime API is designed for bots and integrations to handle messages, events, actions, and webhook requests at runtime. Each request made to this API is authenticated as either a bot or an integration. It can also be accessed externally by providing a bot or integration ID, though doing so effectively authenticates the request as a bot or integration. All the endpoints of the Runtime API are located behind the chat base path (api.botpress.cloud/v1/chat/).
The Runtime API has many nuances that aren’t relevant to bot developers—because of this, we recommend only making your requests using the official Botpress TypeScript Client, which simplifies some of the API’s trickier aspects.If you decide to interact with the Runtime API using another HTTP client, you may experience unintended behaviour or encounter issues.

​
Using the Official TypeScript Client

The official TypeScript client is available as an NPM package. You can install it using any of the following command: 

npm install @botpress/client
Once installed, you can import the client and use it in your TypeScript code: 
import { Client } from '@botpress/client'

const main = async () => {
  const token = process.env.TOKEN
  const botId = process.env.BOT_ID

  const client = new Client({
    token,
    botId,
  })

  const { messages } = await client.listMessages({})
  console.log(messages)
}

void main()
