Webhook 与 Watson Assistant 的集成？

Question

I want to know whether IBM Watson Assistant has the feature of calling webhook.

It means when an intent of workspace is matched Watson Assistant need to send a post request to an external server including the intent in the request body.

Example for a webhook:

https://123.456.789.12:7788/myWebhook/testMethod

IBM Watson Assistant need to send a Post request to this service and that service will return a text string. Watson Assistant should get that text and show it to the user.

That is my usecase. Will it work with Watson Assistant?

i found the below documentation from IBM site. https://console.bluemix.net/docs/services/conversation/dialog-actions.html

It says to update the json response. ie add another key value pair to json object as "action". in the action json array there is "name" parameter. I added above url to name parameter and checked by calling the intent whether a request comes to my web service but it didn't.

following is my json response. i assumed once the intent is matched a post request should go to my web service. but i checked my web service by printing the request body on the console. but no any request came to it. could you please tell me where did i miss?

{
  "context": {
    "skip_user_input": true
  },
  "output": {
     "text": {
        "values": [
             "your current outstanding balance is $my_balance ."
        ],
     "selection_policy": "sequential"
    }
  },
  "actions": [
     {
       "name": "https://123.456.789.12:7788/myWebhook/testMethod",
       "type": "client",
       "parameters": {
           "body": "$body"
       },
      "result_variable": "context.my_balance"
     }
  ]
 }

Answer 1

You found the correct method, ie dialog actions, to implement webhooks.

Watson Assistant supports server- or client-side actions:

• For the server-side action you would set up an action with IBM Cloud Functions. That action would call the webhook.
• For client side, you would pass the information similar to what you show in the question to the app (client). Your app would need to react and to call the webhook.

From what I read about your case I recommend checking out the server-side action. This tutorial about a database-driven bot implements a couple of those actions . Instead of calling the database, you would call out the webhook.

截至 2019 年 8 月，Watson Assistant 中现已集成了 Webhook 功能。

Answer 3

Go to "Options" in the Assistant dialog and enable webhook. Paste the url you got after creating an action from cloud functions. Don't forget to add ".json" to the url you paste in the assistant webhook page. See more information here: https://cloud.ibm.com/docs/assistant?topic=assistant-dialog-webhooks
