Introduction

Webhooks are used to communicate between two different or same systems. You can use webhooks when you want central to send/receive any data from/to other systems. On Central, you can operate webhooks in 3 different manner, which are as follows -

1. Internal Webhooks: Use any of the pre-made internal functions. Use this when you need to use any of the commonly used functions.

2. Webhook Widget: Call any external API using dynamic data and configurable structure. Use this when you want to integrate and use any external API

3. Flow End Webhook: Call the default external webhook for any flow. Use this when you need to push flow details on a particular webhook. TO BE DEPRECATED

Internal Webhook

Custom webhooks are internal webhooks which can be used to pass on the data in between the flow execution.

Using webhook widget, you can simply invoke any configured internal webhook in between the flow and call any specific method to push some data.

You do not need to bother about the request body or need to specify the variables that needs to be passed. You can simply follow the 2 steps to invoke any webhook in between the flow.

List of Internal Webhook

You can use any of the following internal functions. How to configure them is listed below.

1. Initiate Outbound Flow

Using this webhook, you can request to initiate any Outbound Flow of your account using it's API.

URL : http://192.168.1.42:3000/centraloutboundwebhook-v1/prod/‌

Method : createOutbound

R‌equest :

Response :

2. shortURL

‌Using this webhook, you can shorten a long URL to a short URL.

URL: https://s.phonon.in/UrlShortner/phonon/shortUrl

Method: POST

Headers:

Request:

{	
    "custToken": "abcd1234",	
    "longUrl": "https://google.co.in"
}

custToken is static at "abcd1234"

Response:

{  
    "shortUrl": "https://s.phonon.in/BEK4YYnx"

4. updatePauseStatusForCLI - Change Break Status of a Direct Dial Agent

‌Using this webhook, you can change the break status of a Direct Dial Agent. While the Direct Dial Agent is on break, s/he will not be considered for any calls allotment. For example, if your Dialer DID is 91806880080, you can create an Inbound Flow with the same DID with this webhook. DID Agents can call on the Inbound number to change their pause status anytime (or you can toggle it automatically).

‌Notes:‌

1. In the Dialer Flow, you can get the Agent CLI using $call.agent.dnis.number or for Inbound Flow =>$call.cli.number

Custom Webhook Widget

Introduction

This webhook widget is use to call any external API using dynamic data and configurable structure. You can use this when you want to integrate and use any external API in between or at the end of the flow execution.

Step 1: Add Webhook Widget

In the flow designer select the webhook widget and add to the designer screen and connect with the appropriate widget. Now double click on the widget to open the configurations -

Now the select the ‘custom’ option in the URL

Step 2: Configure Request

After you select the custom option, you need to configure the webhook/API request. To configure the request, you need to following configurations -

1. Method : You need to select the method based on the action you need to perform in the API request. The methods supported are GET, POST, PATCH, DELETE, PUT, OPTION, HEAD.

2. Authentication : The authentication method that is required to perform the action on the URL. You can select ‘none’ if there is no authentication required or you can select ‘basic’ and provide username and password for authentication.

3. Headers : Some APIs require you to send particular headers along with sending request, typically to provide additional metadata about the operation you are performing. So by clicking on ‘add headers’ and you can provide headers that are necessary by providing its key and value. You can add multiple headers and mark them as mandatory as well (if required).

4. Body Type : The type of the body in which the request will be send. It can be none, JSON or XML.

5. Body : Here you need to provide the request body, according to the body type selected

6. Query Parameters : Query parameters are appended at the end of the URL. They are extensions of the URL that are used to help define specific content or actions based on the data being passed. You can add multiple query parameters by clicking on ‘add query parameter’ and also mark them as mandatory by selecting the checkbox. You can provide the key and value of the query parameter in their respective text box.

Step 3 : Configure Response

Once the request is configured, you need to configure the response of that request in webhook widget. In order to configure response, follow below steps -

Response Type : Select the type of the response that you will be receiving from API call. The response type can be JSON or XML.

Object Mapping : You can directly save a particular value from the response data in a Flow Variable. To store a response value in a Flow Variable, click on the '➕' button.

In the ‘Save In’ column, enter the Flow Variable in which you want to save the response value.

In ‘Object Map’, enter the path of the response value you want to save. To get the path for:

1. 'JSON' Response Type : When the response type is JSON, in order to find the path of the object you can visit  http://jsonpathfinder.com.

   1. On this page, you can paste your JSON response and on the right side, click on the object whose path you need to find.

   2. You will be able to see the path at the top right corner.

   3. Copy that path and paste in the ‘object map’ area.

   4. Replace ‘X' with 'data’

   5. To know more, you can refer to the help section of the widget.

   6. You can mark any response object as ‘mandatory’, by selecting the checkbox.

2. ‘XML’ Response Type: When the response type is XML, you need to put the XML Path of the response value. Unfortunately, there is no simple online tool that you can use to get that value. You can read about XML Path here and test your path with sample data here. If you need more help, contact our Tech Support Team to help you with the path at support@phonon.io

Step 4 : Other Configurations

After the response parameters are configured, you can configure some additional configurations as follows -

1. Wait for response : Enable if you want to wait for the response of your request. You can play hold music meanwhile by enabling ‘enable hold music’. The maximum response wait time is ‘60 seconds’.

2. Persist Response : Enable if you want to retain the value of flow variables after the flow execution is completed.

3. Error code Flow Variables : Once the execution of webhook widget is over, you will be able to get some of the values in the specified flow variables which are as follows -

   1. On Success -

b. On Failure -

Once the execution of the webhook widget is completed, according to the response the flow will move forward. That is for success response, it will move in ‘line 0’ and for failure response, it will move in ‘line 1’.

Flow End Webhook

On flow complete webhooks are used when you want to push/send all the flow details to the default webhook once the flow gets completed.

In order to send the details on flow complete, you need to follow below steps -

Step 1 : Configure webhook

First step is to configure a webhook(to which the details will be send) and set it as ‘default webhook’. To configure a webhook, you can follow below steps -

1. Go to Advanced → Webhook page

2. Click on ‘add webhook’

3. Select the method as ‘Post’

4. Enter or paste your external webhook URL and click on ‘check button’.

5. Once you see a green tick beside check button, select the authentication method.

   1. None : If there is no authentication required

   2. Basic : If username and password is required

6. Select the body type as ‘None’.

7. Enable ‘Is default webhook' and click on save button.

Step 2 : Enable webhook in flow

Open the ‘Details section’ of the flow for which you want to send details to the webhook.

Enable ‘webhook for the flow’ and done. After ever execution of this flow, all the flow details will be send to the default webhook in the predefined format.

Predefined Format :

{	
    "callDetails": [
		{
			"calleeNumber": "Phone number of the callee",
			"connectTime": "Timestamp of call when started",
			"didNumber": "DID used in call",
			"duration": "Total Call duration in seconds",
			"endTime": "Timestamp of call when ended",
			"hangupCause": "Hangup cause code of the call",
			"incoming": True if the call was incoming false otherwise,
			"startTime": "Timestamp of call when started"
		}
	],
	"keys": [
		{
			"name": "$flow.key.variable1",
			"value": "value of variable"
		},
		{
			"name": "$flow.key.variable2",
			"value": "value of variable"
		} // This will be repeated for all the variables passed during the call
		
	],
	"phonon-uuid": "Phonon uuid of the call",
	"recordingUrls": [
		{
			"recordedFileName": "file name of the recording",
			"recordedFilePublicPath": "URL of the recording, where it is stored"
  }
  ]
  }

Outcome : Everytime the flow is executed, all the flow details (as mentioned in the format) will be send to the default webhook selected.

Note :

1. If you want to send some additional data at the end of the flow in some different format, then you can use a webhook widget after ‘on flow complete’ widget.

2. This functionality will be modified in the near future.
