We have seen how an Alert task can be set up in the Kore.ai XO Platform  here. In this article, we will see how alert task authorization can be set up using the OAuth v2.

How it Works 

1. The Kore.ai application redirects the user to a login dialog at the web application.
2. The user authenticates.
3. The web application redirects the user back to the Kore.ai application with an access token.
4. The Kore.ai application validates the access token.
5. The access token allows the Kore.ai application to access a protected resource at the provider, on behalf of the user.

General Setup

OAuth v2 is the new version of the open protocol to allow secure authorization in a simple and standard method from web, mobile, and desktop applications. To use oAuth v2, you must first register an account with the web application as you will need the log-in credentials for that application to configure the settings for the Authorization Mechanism.

To begin your configuration, follow the steps below:

1. Select the VA you want to work with.
2. Go to Build > Conversation Skills > Alert Tasks. 
3. Select the task you want to work with. 
4. Click the API Request tab within the Alert Task.
5. Expand the Authorization section and click Create New to configure a new authorization.

6. Next, the New Authorization Mechanism window opens, as shown in the illustration below.
   

To configure OAuth1 for your Alert Task, please configure each area presented below. 

Form Fields

To configure oAuth v2, define the fields described in the following table.

FIELD NAME	DESCRIPTION
Authorization Type	Set to oAuth v2.
Callback URL	The URL used by the web application or web service to redirect the end-user after end-user authorization is complete. This value, https://idp.kore.ai/workflows/callback/ is provided as a read-only value by the Kore.ai application when you define oAuth v2 settings.
Identity Provider Name	The name of the web application or web service, for example, Asana. This field is required.
Client ID	The ID of the Kore.ai client.
Client Secret Key	The value provided as the Kore.ai application authentication based on the Client ID to the web application.
Authorization URL	The URL used to obtain end-user authorization for the Kore.ai application to access the web application or web service using the access token. This field is required.
Token Request URL	The URL used by the Kore.ai application to obtain an unauthorized request token. A request token is a value used by the Kore.ai application to obtain authorization from the end-user to obtain an access token. After end-user authorization, an access token can be requested by the Kore.ai application. This field is required.
Scope	If the web service requires additional values for authorization, add one or more Key/Value pairs. For example, some Bot web services support using a scope key using read-only, write, or both as the value.
Refresh Token URL	Add the refresh token URL that you want to use for this authentication.
Auth Error Status Code	When there is an error in authentication, use this field to provide a status code for the particular error.
Description	Provide a description for your Alert Task authentication.

Tenancy

If required, in the Subdomain section, select Yes if the base URL for a web application or user interface uses a tenant name in the URL. For example, kore is the tenant organization for a web service using tenants as www.kore.someCompany.com.

In the following example configuration, the tenancy URL contains the {tenant} organization placeholder.

Additional Fields

1. Click + Add Additional Fields to open the Additional Fields window, and then enter one or more key/value pairs that represent additional authorization input fields if required as shown in the following illustration. 
   
   
2. Specify the following fields:
   1. Field Key – The name of the custom field to specify for authorization.
   2. Value – The value of the custom field to specify for the authorization.
   3. Click Add to save the Additional Field.
3. To add more Additional Fields, click Add in the Additional Fields section.

Authorization Fields

By default, authorization fields are configured as part of the header of the task request message. If your task request requires additional authorization fields or the expected authorization is not part of the header, for example, a verification code,

1. Click + Add Authorization Field and then define the fields as shown in the following illustration.
   
2. In the Field Type field, you can select one of the following depending on where in the task request message and the type of authorization fields that are required.
   1. Header – The VA expects the authorization fields as part of the header of the request.
   2. Payload – The VA expects the authorization fields as part of the content of the body of the request.
   3. Query String – The VA expects the authorization fields as a uery in the body of the request.
   4. Path Param – The VA expects the authorization fields as part of the URL path for the request.
3. In the Field Key field, enter the name of the field for the selected Field Type.
4. In the Field Value field, enter the value for the Field Key specified.
5. Click Add. The new authorization field is added in the Authorization Fields section.
6. To add additional authorization fields, click Add in the Authorization Fields section.

Click Save Auth to save the authorization settings and close the New Authorization Mechanism dialog.

Testing

After you save the authorization, you can test it using the Authorization page.

1. Click Test Authorization before continuing to develop the remaining steps of your task.
2. After you click Test Authorization, the test is executed using the authentication token URLs and the Client ID and Client Secret Key. If the tenancy was defined, the Test Authorization window is displayed as shown in the following illustration.
   
3. Click Test to begin the authorization test. When the validation of authentication is complete, the Test Authorization window is closed and the results of the validation, either success or failure, is displayed to the immediate right of the Test Authorization button. If the authorization fails, the Auth Test Failed message is displayed along with the Headers and Response tabs as shown in the following illustration.
