Using the UiPath integration for Botpress

Disclaimer: This module is currently in beta. Breaking changes might appear in the future. Use in production with care.

About

The UiPath module for Botpress allows you to send messages from your UiPath workflows back to your Botpress instance.

Installation

You must enable the uipath module in order to get started. See here to learn how to enable Botpress modules.

Starting UiPath jobs from Botpress

You can start UiPath jobs from Botpress by leveraging the Botpress SDK and the axios library.

Starting a UiPath job is done in 3 steps:

1. Generate an access token to call UiPath
2. Generate a Botpress Token that UiPath will send back to Botpress. This Token is necessary in order to authenticate calls to send messages back into Botpress.
3. Start a UiPath Job

Here is an example of starting a UiPath job using a Botpress Action:

async function action(bp: typeof sdk, event: sdk.IO.IncomingEvent, args: any, { user, temp, session } = event.state) {
  /** Your code starts below */

  const axios = require('axios')

  /**
   * Generates a UiPath Access Token
   *
   * @param clientId The UiPath Client ID
   * @param refreshToken The UiPath Refresh Token. See https://postman.uipath.rocks/?version=latest to learn how to generate a Refresh Token
   * @return The UiPath Access Token
   */
  const getAccessToken = async (clientId, refreshToken) => {
    const { data } = await axios.post(
      'https://account.uipath.com/oauth/token',
      JSON.stringify({
        grant_type: 'refresh_token',
        client_id: clientId,
        refresh_token: refreshToken
      }),
      {
        headers: {
          'Content-Type': 'application/json'
        }
      }
    )
    return data.access_token
  }

  /**
   * Generates a Botpress Token for the Botpress UiPath module
   *
   * @return A Botpress Token
   */
  const getBotpressToken = async () => {
    const axiosConfig = await bp.http.getAxiosConfigForBot(event.botId, { localUrl: true })
    axiosConfig.params = {
      expiresIn: '1h' // expiresIn is optional. Increase it for longer running jobs. See here for examples https://github.com/zeit/ms#examples
    }
    const { data } = await axios.get('/mod/uipath/auth/token', axiosConfig)
    return data.token
  }

  /**
   * Finds the Release Key for a given UiPath Process
   *
   * @param accountLogicalName The UiPath Account Logical Name
   * @param serviceLogicalName The UiPath Service Logical Name
   * @param accessToken The UiPath Access Token. Use the getBotpressToken() to generate a UiPath Access Token.
   * @param processKey The UiPath Process Key. For example, "MyProcess".
   * @param processKey The UiPath Process Version. For example, "1.10.13".
   * @return The Release Key for the given UiPath Process
   */
  const getReleaseKey = async (accountLogicalName, serviceLogicalName, accessToken, processKey, processVersion) => {
    const { data } = await axios.get(
      `https://platform.uipath.com/${accountLogicalName}/${serviceLogicalName}/odata/Releases`,
      {
        headers: {
          Authorization: `Bearer ${accessToken}`,
          'X-UIPATH-TenantName': serviceLogicalName
        }
      }
    )

    const release = data.value.find(
      release => release.ProcessKey === processKey && release.ProcessVersion === processVersion
    )
    return release.Key
  }

Sending chat messages from UiPath to Botpress

Using the Botpress component for UiPath, you can send back messages from your UiPath workflows to Botpress. This enables you to design UiPath workflows that report back to chat users on the progress of a UiPath Job.

Installation

From the UiPath Go marketplace, download the Botpress component. Install this component to your UiPath Studio.

Usage

The Botpress UiPath component contains the Callback UiPath Activity. The Callback Activity allows your UiPath workflows to send messages back to your Botpress instance.

Configuring the Callback Activity

The following properties can be configured for the Callback Activity:

• (REQUIRED) ExternalURL: The external URL for your Botpress instance. Examples: "https://botpress.yourdomain.com", "http://192.168.1.8:3000"
• (REQUIRED) Message: An object representing the message you are sending back to your Botpress instance. Example: New With {Key .type = "text", Key .text = "Hello, this is a response from UiPath!"}
• (REQUIRED) BotId: The ID for your Botpress Bot which will handle the message. Examples: "mybot", "hrbot"
• (REQUIRED) BotpressToken: The Botpress Token required in order to send back a message to your Botpress instance
• (REQUIRED) Channel: The channel on which your bot will send back the message. Examples: "web", "messenger"
• (REQUIRED) Target: The user ID to which the message will be sent. Example: "Sth3X70cccOkbm-ziPwc"
